Digital Gauges and Controllers

Digital gauges

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

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.

As these gauges utilise the same technology as their Active counterparts, with the same LED 360° light ring indicator and integrated set-point relay: they are a perfect upgrade for those looking to increase data collection.

We provide digital versions of our APG200, AIM200, and WRG200 ranges, known respectively as: nAPG200, nAIM200, and nWRG200.

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

Active Pirani Gauge (nAPG200) the perfect vacuum solution across a spectrum of applications and 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 LED 360° light ring indicator enable better maintenance of systems, to Research and development for whom the local pressure indication helps to monitor experiments away from the main interfaces.

  • 360° LED light ring pressure indicator
  • Compact size
  • Long filament
  • Integrated filter
  • Drop in compatible
  • Wide range power from 15-48V power supply
  • Digital/Analogue
  • Set-point relay

Active inverted magnetron gauge

Edwards Active inverted magnetron gauge (nAIM200)

Active inverted magnetron gauge (nAIM200)

Active Inverted Magnetron Gauge (nAIM200) 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 nAIM200 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. They have a very low external magnetic field and 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.

  • 360° LED light ring pressure indicator
  • Reduced footprint
  • Multipoint star striker
  • No external controller needed
  • Drivers available
  • Drop in compatible
  • Wide range power from 15-48V power supply
  • New magnets
  • Set-point relay
  • Variant compatible with C-clamp

Wide range gauge cold cathode/pirani

The Wide Range Gauge (nWRG200) 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 nWRG200 has many novel features, including a patented striker, push-button calibration and set-point controls and comprehensive diagnostics. The nWRG200 is a cost-effective vacuum management solution when used either with an Edwards controller or directly integrated into the vacuum system controls.

  • 360° LED light ring pressure indicator
  • Reduced footprint
  • Filament technology
  • No external controller needed
  • Drivers available
  • Drop in compatible
  • Wide range power from 15-48V power supply
  • New magnets
  • Set-point relay
  • Variant compatible with C-clamp

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 nWRG200 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
