Digital Gauges and Controllers

Built upon our stable platform of active analogue gauges, we offer digital variants able to communicate via RS232 or RS485 with your system.

We provide digital versions of our APG200, AIM, and WRG ranges, known respectively as: nAPG200, nAIM, and nWRG.

Measuring from atmosphere to 1e-9mbar, and with corrosion resistant/industrial versions, you can select the right gauge for your application.

Edwards APG200 pirani gauge

Edwards new 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.

Edwards production facility in the UK has been making and
designing vacuum gauging for decades. With this experience
we have been able to develop a gauge that has a 25% reduced
package size, with no reduction in performance.
With a range of upgrades and feature enhancements, the
APG200 is suitable for all vacuum markets, from Analytical
instruments who can take advantage of the reduced size and
flexible outputs, to Semiconductor for whom the new interfaces
and light rings enable better maintenance of systems, to Research
and development for whom the local pressure indication helps to
monitor experiments away from the main interfaces.

Edwards digital gauges range

Edwards digital gauges range

Digital active gauges are similar to analogue active: they are self-contained including driving electronics, but they take this one step further and eliminate the need for a separate controller due to having serial comms onboard.


The Digital gauges simply need a supply voltage in the range of 15 to 48V and then can be directly interrogated via a PC or PLC using either RS232 or RS485 communications.
