Pirani Gauge

Monitoring made easy with vacuum gauge controller

Properly monitoring of vacuum pressure and statistics is important for smooth functioning of your vacuum systems. Our HHV Pumps PGC series vacuum Pirani Gauge Controller (PGC) is just what you need.

It displays vacuum pressure as measured from a PGS21 sensor tube. The model PGC21 displays vacuum measurements from 100 mbar to 0.001 mbar and has a built in potential free contact set point relay output. The sensor tube has built in zero and atmospheric pressure adjustments, so that the sensor tube can be used as a transducer, and each sensor is factory calibrated at sensor level. With this, one-on-one replacement of sensor with the display unit is established, and there is no dependency on vacuum gauge level adjustment in case of sensor replacement.

 It is also available in two variants – single gauge head and double gauge head.

Features of Pirani Gauge

  • PGC21 displays vacuum range measurement from 100 mbar to 0.001 mbar
  • Displays pressure in three units – mbar, Torr and Pascal with button for inter­ changeability.

  • The replacement of the sensor can be done without dependency on gauge controller

  • Decimal reading allows you to quickly note the readings without having to convert between the Ten’s powers.

  • Output has RS485 connection which can be connected to the Distribution Control System (DCS).

Benefits of the HHV Pumps Pirani Gauge Controller

  • Easier vacuum pressure monitoring

  • Great for controlling High Vacuum systems

  • Useful for creating safety circuits in vacuum systems

  • The availability of two set points give the user more flexibility in terms of monitoring and control.
