Low pressure transmitters with 4 to 20 milliamp current output for measuring low level gauge, differential & absolute pressures below 1 bar (15 psi, 400 inWG or 1000 mbar). Low pressure transmitters are used to measure air ventilation pressures in buildings and small pressure differences between two different locations such as clean rooms and laboratories where it is important to prevent air contamination.

Low pressure ranges are required to measure small pressure values, often between two locations where air is being moved from one place to another. Low range pressure measurement is required for monitoring and controlling ventilation and air extraction in office and factory buildings. In building management applications, air movement in large spaces creates very small changes in air pressure, so it is necessary to use highly sensitive measurement devices which are set to read in inches of water column, mbar, hPa or Pascals.
Pressure transmitters are measurement devices which combine amplified 4 to 20 milliamp current loop output signal conditioning electronic module with a transducer for measuring the pressure of a liquid, vapour or gas.
