Differential pressure transmitter and pressure transmitter

A differential pressure transmitter measures and monitors positive or negative pressure. It often concerns the low pressures that need to be measured in environments such as cleanrooms.

Pressure transmitters forward the data so it can be read for regulation and/or monitoring purposes. They are often used in industrial applications and for measuring high-pressure values.

 

What is a differential pressure transmitter?

When we talk about measuring differential pressure, we are referring to determining the difference in pressure levels between two locations. We do this by using a differential pressure transmitter. The output signal is either analogue (0..10V or 4..20mA) or digital, e.g. using Modbus protocol.

In certain sectors, measuring differential pressure is quite literally a matter of life and death. Cleanrooms need positive pressure to ensure production processes take place in particulate-free air. Differential pressure sensors measure and monitor positive or negative pressure and use the data to control the ventilation or building management system.

Pedak’s differential pressure transmitters are mainly used for measuring differential pressure and monitoring negative or positive pressure in cleanrooms such as hospital operating theatres. Positive pressure is created in cleanrooms or operating theatres so that contaminated air (containing potentially harmful bacteria, viruses, etc.) cannot enter them.

 

What is a pressure transmitter?

Pressure transmitters measure the relative and absolute pressure of gases and liquids. They are used to measure high pressures in industry.

 

Pressure transmitter applications

For measuring absolute and relative pressure, Pedak supplies a range of screw-in pressure transmitters. These come in a variety of ranges and process connections, from vacuums to industrial process pressures of up to 600-Bar.

 

Stringent requirements for pressure transmitters

In various industries, measuring pressure is vital, not only in terms of safety but also to ensure the smooth running of production processes. To ensure measurements are as accurate and reliable as possible, pressure transmitters always come calibrated within the set values.

 

Which pressure transmitter or differential pressure transmitter do you need?

Pedak has pressure transmitters and differential pressure transmitters suitable for a wide range of conditions. For instance, there are pressure transmitters with auto-zero calibration. These are perfect for high-precision measurements in rooms with low differential pressure. Pedak also has pressure transmitters and differential pressure transmitters that are designed to use in hazardous areas (ATEX zones).

Depending on the application, Pedak can supply differential pressure meters with the following features:

  • Accurate, stable and reproducible measurements
  • Auto-zero calibration
  • Bi-directional differential pressure sensor
  • With or without display
  • Solutions for measuring differential pressures ranging from -100 to +2000 Pa
  • Pressure measurement from -1 Bar to 600 Bar
