Passive Gauges and Controllers

Passive Gauges and Controllers

Gauge

Whilst active gauging now dominates the market, there are still niche applications in which passive gauging is supreme. These include any application where having electronics close to the experiment would result in failure of the device. Drive electronics are still needed to control the gauge, but these can be kept remotely in our dedicated controller that can be placed up to 50m away from the gauge to give a “local” display and pressure output to your system.

Edwards Passive gauges are gauge heads without onboard electronics: well suited to environments with high amounts of radiation or very high ambient temperatures.

The head that is attached to the system only contains the items needed for the physical measurement and all other electronics is contained in the controller. As such the controller and cable have to be specific to the desired gauge.

Rugged and accurate solutions for the harshest environments:

  • Perfect for High Energy Physics and R&D applications where radiation would damage a normal active gauges electronics. These gauges have a long and proven track record in such environments.
  • With these applications often requiring Ultra High Vacuum pressures, our passive gauges have the widest measuring range, able to achieve measurement down to 2e-12mbar with our IG40-EX range.

Dedicated controllers

Passive gauges electronics are kept in a separate controller, which is what enables them to cope in irradiated environments. Two controllers are available in the range: analogue and digital outputs, on board set points to offer you the choice on how to integrate into your wider system.

  • PGC201 – driving 2 pirani gauges (PRG20K) and one cold cathode gauge (CPG35K).
  • PGC202 – driving 2 pirani gauges (PRG20K)and one hot cathode gauge (IG40BA or IG40EX).
  • Rugged gauge head more resistant against ionising radiation
  • Bakeable UHV gauge heads can be baked to high temperatures
  • Widest measuring range ability to measure from atmosphere to 2e-12mbar
