Edwards proven technology: Select the right gauge for your application needs.

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 new series of gauges that has a 25% reduced package size, with no reduction in performance.

With a range of upgrades and feature enhancements including an LED light ring visual pressure indicator and set point relay enabling you to trigger a wide range of knock-on actions.

The advanced generation of gauge:

 

 

Active pirani gauge

The Active Pirani Gauge (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. 

  • 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 (AIM) gauge

Active inverted magnetron gauge (AIM)

The Active Inverted Magnetron (AIM200) Gauges provide accurate measurement over the vacuum range of  1 x 10-2 to 1 x 10-9 mbar. This gauge is rugged and reliable in a wide range of applications, ranging from scientific instruments to industrial processes.

The AIM200 Gauge is an inverted magnetron gauge head and gauge controller combined into a single compact unit, and features a very low external magnetic field, coupled with an improved striking mechanism makes it ideal for use with sensitive analytical instruments or in applications where the gauge needs to be mounted in close proximity to sensitive equipment.

  • 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 (WRG200) offers the capability of single port pressure measurement in the range atmosphere to 10-9 mbar, covering not only initial chamber pump down, but also process pressures all in one.

The WRG200 Gauge is rugged and reliable in a wide range of applications ranging from scientific instruments to semiconductor and industrial processes as it utilises the latest in filament pirani and cold cathode technology. The WRG is an all-in-one gauge giving you the advantage of switching from the rough vacuum sensor to the high vacuum sensor automatically and has a low magnetic stray field to ensure no interference with the surrounding environment.

  • 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

The original generation of gauge:

Active linear convection vacuum gauge (APGX-H)

Active linear convection vacuum gauge

The Active Linear Convection Vacuum Gauge (APGX-H) has a wide measuring range from 1333 to 3 x 10-4 mbar. The use of convection technology ensures accuracy and sensitivity are maintained to the top of the pressure range compared to conventional Pirani gauges, which lose accuracy above 100 mbar. The gauge is compact and may be mounted in any orientation, simplifying installation where space is limited.

Active ion gauge

The Active Ion Gauge (AIGX) is a compact active ion gauge with dual yttria coated iridium filaments, a wide measuring range from 6.6 x 10-2 to 6.6 x 10-10 mbar, and a 1 Volt/decade linear output. The AIGX incorporates all benefits of the industry standard active gauging concept, with integral electronics and replaceable tube. The gauge has a degas facility and includes features to protect and extend the life of the filaments. The AIGX benefits from extremely low emissions of charged particles, which makes it an excellent choice for processes where background noise is undesirable.

The Active Hot Cathode Wide Range Gauge (WRH) offers the ability to measure from atmosphere to 10-10 mbar with a single gauge, with accuracy and repeatability. The WRH gauge utilizes 2 measurement methods (bayard-alpert & pirani) in a single package, giving you everything you need to measure and control your system. With analogue and RS485 output available via the D-SUB connector, 2 onboard relays and easy calibration, control and monitoring is simple.

Utilising the included software, you can easily track and log your system’s performance and also make adjustments to the gauges behaviour, such as setting the set points or changing the output scaling. This gauge is the perfect companion for many applications, from R&D institutes to high-end mass spectrometry through to general industry.

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 APG200 Pirani gauges, available in standard and corrosion resistant variants, for measuring from atmosphere to 1 x 10­4 mbar to our WRG 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.

Active gauge range

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
