WRG-S - DN 40 CF - St St Wide Range Gauge, Wide Range Gauge, D14703000

Gauge Indirect Pressure Measurement

Indirect braod range vacuum gauges are the best choice when the pressure needs to be measured over a wide range and when good accuracy is needed across the whole range. Reliable vacuum gauges are essential to ensure your system’s accuracy and control. Our vacuum gauging solutions include the WRG Series Cold Cathode Combination Gauge, AIM Series Cold Cathode Gauge, and APG Series Pirani Gauge.

WRG Series

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

This gauge is particularly suited to monitoring the pressure on systems that are rapidly pumped down from atmosphere pressure to high vacuum levels.

For applications that require extended pressure monitoring in the 10-2 to 10-4 mbar range Edwards recommends using a separate Active Pirani (APG200).

Features and Benefits

• Single push-button atmosphere setting
• Ultra compact, featuring recessed electrical connector
• Easy service; both Pirani and magnetron elements are individually replaceable
• Low magnetic field version (SL) available for particularly sensitive applications e.g. mass spectrometry and microscopy
• Comprehensive failure mode diagnostics facility
• Compatible with Edwards TIC, TAG and ADC controllers
• D-type version including cable strain relief and enhanced ingress protection (IP44)
• Magnetron uses an advanced technique for highly reliable striking, even at high vacuum or in relatively contaminated conditions
• Automatic vacuum setting of Pirani gauge element
• Easily programmed set point covering entire measuring range
• Extended service intervals and gauge lifetime, through reduction of HT voltage after ignition and low discharge current
• Microprocessor signal processing gives seamless transition between Pirani and magnetron outputs as well as linear output (log pressure scale)
