New Gauge Controller
Radiation resistant and Bakeable Gauge system
Edwards is proud to introduce our new range of passive gauge heads and controllers, selected specifically to complement the current Edwards range of active gauges and controllers. These passive gauges offer a solution for measuring pressure in a wide range of applications, from UHV systems to process industries or wherever the use of an active gauge is not possible e.g. Cyclotrons.

Selecting the right Gauge for your application
Selecting Your controller
Edwards PGC201 controller covers the pressure range between 10⁻⁹ and 1000 mbar by combining two measurement principles from the PRG and CPG gauges. The PGC202 combines PRG gauges and IG40 BA or IG40 EX gauges for measurements of vacuum pressures in the range between 10⁻¹² and 1000 mbar. Both these controllers provide monitoring and control functions for the connected gauges.
