You Need To Know About Pressure Transmitter

1# What Is A Pressure Transmitter?

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.

2# What Is The Working Principle Of A Pressure Transmitter?

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.

15# What Is The Difference Between A Pressure Transducer And a Pressure Transmitter?


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.


16# How To Choose The Best Type Of A Pressure Transmitter For Industrial Applications?

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.

Similarly, lukewarm water is equally efficient in removing non-greasy dirt particles. Give it sufficient time to dry. Do not directly submerge it into the tank. Cover the surface, and it is ready to use again. However, follow the instructions of the manufacturer to achieve the desired results.

24# How Can We Test A Pressure Transmitter?


Please follow these simple steps to test a pressure transmitter:

  1. First, connect pressure transmitter hose from calibrator to transmitter and then connect mA jacks.
  2. Accurately select the pressure selection knob, close the vent knob, and then supply pressure to the metering valve.
  3. Apply pressure and then release it for a specific interval. Always maintain a particular interval of the gap.
  4. Keep on reading the reference pressure and current output from the device.
