Digital Gauges and Controllers

Built upon our stable platform of active analogue gauges, Digital gauges are similar, but they take this one step further and eliminate the need for a separate controller due to having serial comms onboard

As these gauges utilise the same technology as their Active counterparts, along with being in the same form: they are a perfect upgrade for those looking to increase data collection.

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

Measuring from atmosphere to 1 x 10-9 mbar, and with corrosion resistant/industrial versions, you can select the right gauge for your application.

Active pirani gauge

Edwards APG200 Left Angle Top Front View

Edwards APG200 pirani gauge

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 nAPG200 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.

Active inverted magnetron gauge

Gauge digital

Edwards Active inverted magnetron (nAIM) gauge

Active Inverted Magnetron (nAIM) Gauges provide accurate measurement over the vacuum range of 1 x 10-2 to 1 x 10-9 mbar. These gauges have proved to be rugged and reliable in a wide range of applications, ranging from scientific instruments to industrial processes. The AIM-X Gauge is an inverted magnetron gauge head and gauge controller combined into a single compact unit, and features a linear output for easy integration with a computer or PLC. The XL variants have a very low external magnetic field, these are ideally suited for use with sensitive analytical instruments or in applications where the gauge needs to be mounted in close proximity to a turbomolecular pump.

Cold cathode/pirani wide range gauge

Gauge Digital nWRG

Edwards Wide range gauge (nWRG)

The Wide Range Gauge (nWRG) family offers the capability of single port pressure measurement in the range atmosphere to 10-9 mbar, with a linear output. It’s a compact solution, halving the space and connectivity hardware requirement, which can be all important in many applications. The nWRG has many novel features, including a patented striker, push-button calibration and set point controls and comprehensive diagnostics. The nWRG is a cost-effective vacuum management solution when used either with an Edwards controller or directly integrated into the vacuum system controls.

  • Reduced overall costs
  • No external controller needed
  • Drivers available
  • Increased ease of integration
  • Wide range power
  • Able to operate from 15-48V power supply

Flexibility to tailor your system:

With every process having a specific requirement, you can see we offer multiple gauge types to make sure you have the right gauge for your need.

From our rugged nAPG200 Pirani gauges, available in standard and corrosion resistant variants, for measuring from atmosphere to 1 x 10­4 mbar to our nWRG Cold Cathode/Pirani combination gauges, to measure from atmosphere down to 1 x 10-9 mbar.

Controllers - local display and control of your system

  • For those wanting off the shelf solutions, we offer basic single/dual head gauge displays via our ADC product line.
  • For those wanting more connectivity and control we have the TIC product line. This is able to control up to 6 gauge heads and to trigger other actions in your system via the RS232 interface/set point output.
  • Variants are available that can control our small dry pump ranges and nEXT turbomolecular pump ranges, enabling you to create miniature systems.

Key features in a nutshell

 
  • Universal controllers: Each controller is able to control a mix of active gauge types
  • Calibration: All our gauges can be purchased with an additional calibration certificate 
  • Service: Simple service procedure for each gauge with no tooling needed for the majority of processes
