Active Pirani Vacuum Gauge
Edwards APG series are Active Pirani vacuum gauges which filament forms one arm of a Wheatstone bridge which is balanced at atmospheric pressure and becomes unbalanced as the pressure decreases.
They are available in two versions, electrical and digital, and each of them in two models, the -M is the standard model and measures to 5⁻⁴ mbar, the -LC is a corrosion resistant version with measurement to 1⁻⁴ mbar.
The newest APG200 series high performance compact Pirani Gauge is the perfect vacuum solution across a spectrum of applications due to its compact size, LED light ring and integrated set points.
All gauges feature compact size for easy installation, a serial output and a replaceable sensor tube. They are also CSA and C/US approved as well as fully RoHS compliant due to their lead-free construction.

With our new light ring, seeing what pressure your system is at, away from the central interface is now possible
Our latest APG200 gauge is famed for harsh duties (with filaments made of Tungsten/Rhenium, Platinum/Rhodium and Platinum/Iridium), ensuring that your Fab is running 24/7 even in these conditions is vital. Therefore strict monitoring of all parts can ensure maximum uptime.
The APG200 has a dedicated set point relays available, enabling you to trigger a wide range of knock on actions.
The integrated filter enables you to truly fit and forget as the filter rejects particles that would otherwise damage the measuring cell
Last thing you want to do is change software or carry out lengthy qualification. Therefore we have made sure that we provide variants to cover the most commonly used outputs so upgrading is even easier
A 25% reduction in volume compared to the APG100, without any loss in performance
Our 15-48V power input is the widest available on the market, enabling you to run these gauges on whatever power
Our digital gauges sit in the same footprint as our analogue gauges, making it easy for you to upgrade at a later date should more data-collection/control be needed
