Our sensors are world-renowned for providing accurate, low drift, high resolution data in the most extreme conditions. Typical calibrations can result in less than ±1.0 psi in error for a 10 kpsi transducer across the calibrated temperature range.

The sky is probably the limit when it comes to what applications pressure transducers can be used in. To give you an idea, you can purchase a barometric pressure transducer to measure atmospheric pressures, hydraulic pressure transducers to measure pressure in your line, compound pressure transducers to measure positive and negative pressures, submersible transducers for level or depth monitoring, and many more special purpose pressure transducers.

Pressure transducers are of the greatest utility for industrial and laboratory data acquisition and control applications. While the number of applications are almost as limitless as the types of pressure transducers, here are some of the most common applications our customers use pressure transducers for:

Strain gage transducers are available for pressure ranges as low as 3 inches of water to as high as 200,000 psig (1400 MPa). Inaccuracy ranges from 0.1% of span to 0.25% of full scale. Additional error sources can be a 0.25% of full scale drift over six months and a 0.25% full scale temperature effect per 1000F.

Using a gauge pressure transducer in an open system underneath the bottom of tank or on an output line to measure the weight of the water to the top of the tank.

Multiple pressure transducers can be attached to pipes either above or below ground to help detect a break or leak in a pipe. The precise location of the leak is indicated by the transducer that is showing the largest drop in pressure. A wireless pressure transducer also makes it possible to remotely monitor for leaks.

To detect a gas leak, you will need a reference pressure against which to measure the pressure that is going into the tank. If the pressure goes down, the output will go up, indicating the presence of a leak.

When non-combustible gas is stored in a tank, a pressure transducer can be used to measure the pressure and how that pressure might be affected by environmental factors like heat from the sun or cold temperatures. If measuring a combustible gas, you will need to use a transducer built with an explosive-proof housing or a hazardous pressure transducer that is certified safe to use with explosive gases.

There are numerous applications where it is necessary to know the pressure a pump produces. The size of the pump will determine the size of the pressure transducer required. For very small pumps, you will need to use a micro pressure transducer. For bigger pumps, a regular pressure transducer will work. However, in a larger pump there is some concern of water hammer, which can damage a pressure transducer. To avoid this issue, for larger pumps you can move the pressure transducer downstream to allow the force of the pump to even itself out before it reaches the transducer.

In some environments you will need to measure the pressure of a gas or fuel at extremely high temperatures. To protect the pressure transducer against these high temperatures, you will need to apply a siphon effect, where the transducer is moved away from the process and the fluid (liquid or gas) first runs through a section of metal pipe to dissipate the heat of the media being measured. The larger the tube used in the siphon, the shorter the distance can be between the process and the pressure transducer.

Differential pressure transducers are one of the most common ways to measure flow rates. The process requires a primary element, such as an orifice (plate) or venturi tube. This element creates a pressure drop by creating a restriction in the pipe. The pressure drop is measured by the differential pressure transducer.

Differential pressure transducers can be used to measure the different pressures on both sides of a large filter bag, known as a baghouse, which is used to clean particulates from the air brought out of a factory. As a bag collects particulates from the filtering process, the differential pressure increases across the bag because less air is able to get through the dirty filter bags. The clean air is sent to air conditioners and sent back to the factory, and the filter bags are replaced when needed.

Many pressure transducers are found in automotive, air craft, and other manufacturing test stands. Anywhere you need to measure water pressures, fuel pressures, or air pressures on cars, planes, and other manufactured products, you will find test stands.

Keeping the bottle filling apparatus with product is a key concern for plants and farms who deal with producing drinking materials for the public. Brewing and dairy applications use special sanitary pressure transducers to measure the pressure in bottling lines.

Pressure transducers for high-temperature steam are devices used in setups where normal pressure transducers fail to operate because of the extreme temperatures. Normal-pressure transducers are sensitive to temperature after a certain point due to the expansion of internal parts caused by the rise in temperature. Such changes can cause errors in the output. Normal-pressure transducers are commonly rated for temperatures between 51° to 93° C.

However, high-temperature pressure transducers are specifically designed to handle high temperatures of the steam. They usually use a piezoelectric core for the measurement of pressure, making them resistive to high temperatures. There are pressure sensors that can measure pressure at temperatures well above 1000°C. However, sensors for such extreme cases are used only for short-term measurements with intervals in between to cool off the sensor.

If you are looking for fine-quality pressure transmitter products and accessories, you are at the right place. The pressure transmitter is a pressure measurement device that accurately measures the pressure difference for multiple fluids and gaseous substances.

A pressure transmitter is a mechanical sensor that measures the expansive force of a liquid and gaseous material. The electronic components convert applied force into an electrical signal on the pressure sensor. It is made up of pressure-sensitive steel, silicon, iron, and many other materials. A pressure transmitter is suitable for monitoring the applied force in pressure-sensitive environments, including pharmaceutical industries, petrochemical industries, gas industries, laboratories, and many other areas. It measures the proportion of pressure in Pascal Pa or Pounds per Square Inch Psi. The accurate measurement of force appears to be a safe and seamless process to enhance the delivery and eventual industrial application.

It works on the principle of differential pressure. The differential pressure is a force applied per square unit area. A pressure transmitter connects electronically to a sensor. A pressure applied on the surface of a pressure transmitter produces changes in its capacitance. It changes the oscillatory frequency of the sensor. Hence, a pressure transmitter detects this change. As a result, a pressure transmitter translates this change into s standard output signal. It helps the users to maintain optimal working conditions that produce the best outcomes in an industrial unit.

The installation of a pressure transmitter is a straightforward process. However, there are multiple options for the safest and reliable installation of a pressure transmitter. First of all, analyze the requirements of the industrial unit for accurate installation of a pressure transmitter. For example, a pressure transmitter can be installed quickly at the bottom using a flange in a filled-sealed container if there is an open tank. Similarly, a pressure transmitter can be installed with a sealed pot if there is a steam flowmeter with an orifice plate. Hence, establishing a pressure transmitter depends on the application and requirements of industrial units.

A pressure transmitter is a helpful device to measure the pressure inside machinery. However, the following key points are essential to consider before buying a pressure transmitter:

Always find out the operating conditions for a pressure transmitter. It helps to increase the life span of a pressure transmitter for industrial applications. For example, choose a pressure transmitter made up of stainless steel for outdoor applications.

Always consider optimal pressure values for working a pressure transmitter. Choose maximum safe overpressure range, frequency, and average operating pressure value.

Always pay attention to the medium in which a pressure transmitter will work. Make sure that a pressure transmitter can withstand all external conditions without affecting its functioning.

A pressure transmitter is also suitable for connecting to other devices to measure depth, altitude, pressure flow, and water flow to ensure the smooth working of the system.

It is a high-precision device suitable for measuring pressure in multiple industrial units, including boiler, pharmaceutical, petrochemical, gas, laboratory, automotive, and many other industrial departments.

Usually, a bidirectional pressure transmitter is made from corrosion-resistance material to improve its longevity. It is sensitive to measure 0.1% changes in pressure differences. It can also withstand high-pressure ambient without losing its accuracy.  You can purchase a ready-to-use bidirectional pressure transmitter from BCST at very affordable rates.

Generally, the terms “pressure transducer” and “pressure transmitter” are used interchangeably. However, there is a significant difference between these two terms. A pressure transducer measures pressure or force and then converts it into an electrical signal. However, these signals are not linearized or compensated by temperature changes. On the other hand, a pressure transmitter measures pressure difference, converts it into an electrical signal, and amplifies the receiver’s signal. It can also transmit signals to remote receivers. Likewise, these signals are temperature compensated and linearized. Moreover, a pressure transmitter offers multiple calibration options.

There are different pressure transmitters, including absolute, differential, gauge, magnetic flow, and bidirectional. Always identify the industrial requirement before selecting the right type of pressure transmitter.

It is the most critical point to consider before buying a pressure transmitter. Always pay attention to the minimum and maximum pressure bearing range.

Always choose a pressure transmitter that shows accuracy ranging between 0.5% and 0.05%. A higher accuracy range can detect minute pressure changes in the environment.

Our experienced quality assurance team members perform multiple quality tests on pressure transmitter products to maintain our quality standards. We have the latest tools and test machines to perform a variety of tests on our products. We meet international manufacturing standards to ensure the durability and reliability of our products. All tests are performed under the supervision of expert team members. We perform the following tests:

We pass pressure transmitter products through a single shock test, continuous shock test, long-duration vibration, short-duration vibration, and broadband noise test to check their reliability.

This test involves storing pressure transmitter products at 110C for approximately 48 hours and -40C for about 24 hours. It determines the zero-point functionality of pressure transmitter products.

We perform chemical resistance tests in a salt-spray machine. For example, a 5% salt solution is sprayed over a pressure transmitter at 35C for 96 hours. Likewise, we perform an ozone resistance test in which a pressure transmitter is exposed to dry and liquid phase ozone at 50C for approximately 6 hours. These tests accurately measure the working efficiencies of pressure transmitter products.

We perform 6 temperature resistance tests, including dry heat, condensation, humidity, freezing, ice water, and rapid-temperature cycling tests. All these tests detect the capacity of a pressure transmitter to withstand extreme temperature conditions in both internal & external environments.

We perform this test to check the resistance of a pressure transmitter in case of dielectric breakdown or electrical short causing the sudden flow of electricity.

We perform this test to check whether or not our pressure transmitter products meet IP69K & IP67 ingress protection parameters. The pressure transmitters are either submerged under 150 bar pressurized water for at least 10 seconds or submerged in the depth of 1-meter water for approximately 30 minutes.

We perform this test to check the efficiency of a pressure transmitter to withstand a high-pressure environment. We pass products through short-time and long-time hydraulic pressure to determine their pressure resistance capacity.

BCST manufactures high-quality pressure transmitter products at very affordable rates. We maintain international quality standards to meet the reliability of the pressure transmitter. However, we offer repair services to all our pressure transmitter products & accessories in case of any damage. We request our customers not to rely on a third party for repairing a pressure transmitter. We have specialized tools and expertise to improve sensitive areas of a pressure transmitter. Our experienced professionals have hands-on experience analyzing all kinds of faults to serve our customers in the best possible ways. However, we take a minimum of 10 days to repair pressure transmitter products and accessories.

It is straightforward to clean a pressure transmitter. However, environmental conditions can cause contaminations in a pressure transmitter. That’s why it is essential to clean a pressure transmitter at regular intervals to improve its working efficiencies. It requires special care and attention. Get a clean cotton pad, dip it in alcohol, and degrease the surface.

Hence, a pressure transmitter directly measures fluid & gas flow speed, water level, and pressure rate.

Hydraulic data transmission requires sensitive pressure sensors capable of enduring high pressures. This is particularly true when used in measurement while drilling (MWD) applications.

MWD has become a standard application, especially for offshore directional drilling. Real-time data collection is essential for measuring the trajectory of the hole as it is drilled. For this purpose, various sensors are mounted on the drill head to provide information about the drilling environment in real time. Inclination, temperature, ultrasound and also radiation sensors are used. These various sensors are physically or digitally connected to a logic unit that converts the information into binary digits. The downhole data are transmitted to the surface via mud pulse telemetry. In addition to monitoring and controlling the drilling process, the data are used for further aspects, including:

Mud pulse telemetry is a binary coding transmission system used with liquids. This is achieved by a valve that varies the pressure of the drilling mud within the drill string and thus converts the recordings of the sensors mounted on the drill head into pressure pulses. The pulsations reach the surface via the drilling mud. The pressure pulses are measured on the surface by a pressure transmitter and converted into an electrical signal. This signal is transmitted to a computer and digitized.

STS provides offshore directional drilling companies with analog pressure transmitters optimized for mud pulse telemetry. The sensors have to meet high demands: They must be extremely sensitive in order to reliably register even the smallest pressure differences. At the same time, the sensors must withstand pressures of up to 1,000 bar. Very high pressures are required to power the drill head in very deep drill holes. The pressure transmitters used for mud pulse telemetry on the surface are also exposed to these forces.

In addition to the high sensitivity, very fast response times are required to ensure good data communication in real time. In order to exclude falsified measurement results, the measuring instrument should be low-noise. The mud pumps in particular can cause the most signal noise in drilling applications. The drive of the drill is another source of interference. For this reason, analogue sensors with a 4 – 20 mAoutput signal are the best solution for mud pulse telemetry.
