Edwards WRG Cold Cathode Pirani

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, pushbutton 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.

Features & Benefits

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