Related Product and Application Guides
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.
Intrinsically safe approved instrumentation can be installed in hazardous area zones and connected to other appropriate intrinsically safe equipment. Intrinsic safety is achieved by limiting the amount of electrical power that can enter the protected zone by incorporating zener diode or isolation transformer barriers, ensuring a specified surface temperature is not exceeded, and preventing electrical discharges which may otherwise ignite a potentially explosive atmosphere.
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.
