How To Choose the Right Pressure Transmitter For Your Applications

Over the years, pressure transmitters, also called pressure transducers or pressure sensors, have proved to be convenient, accurate, and dependable devices for measuring fluid pressure in a wide range of applications, from HVAC/R compressors and variable speed pumps to industrial pipelines and more. There are several models of pressure transmitters on the market, those of which have advanced heat dissipation, reduced creep and hysteresis effects, among other features for use in harsh environments exposed to hostile and corrosive media.

Due to the multitude of models available, it can be tough to narrow down your options. One must consider potential applications and installation locations, as well as a number of other factors. While there is no right way to go about making a selection, there are a few parameters to consider. In this blog, we will be providing a guide to help you select the right pressure transmitter for your operations.

To meet your operational requirements, getting the right pressure transmitter is paramount. Some of the factors to keep in mind include long-term stability, insensitivity to vibration, flexibility and repeatability, custom calibration, energy efficiency, and many others. It is also important to consider the pressure range your pressure transmitter will be operating in; thus, you must consider the following questions:

  • What is the pressure range that the transducer will measure?
  • What is the maximum pressure the transducer will encounter?
  • What is the potential for over-pressure in the system?
  • What is the proof pressure?
  • What is the burst pressure?

Construction and Compatibility

As pressure transmitters are placed in extreme operational conditions, they must be constructed with durable materials that can withstand atmospheric uncertainties. As such, pressure transmitters with an all-weld construction and an IP rating are preferred. Because they come in contact with varying media, checking media and material compatibility is crucial. You must verify that your specific model can handle motor oil, brake fluid, refrigerants, hydraulic fluids, seawater, wastewater, tap water, oxygen, compressed air, and nitrogen for a long period of time. Moreover, the sensor components, such as the diaphragm, fittings, and welds are capable of handling media like ammonia, ionized water, salt water, hydrogen, acids and jet fuel. You must also check your pressure transmitter for shock and vibration protection, as well as ingress protection requirements for your applications.

Other Important Considerations:

  • Sensing technology and circuit design
  • Measurement limit of the sensor
  • Repeatability
  • System accuracy
  • Regulatory factors
  • Power consumption
  • Possibility of modification or customization
  • Handling and installation
