Active Wide Range Gauge

Edwards Active Wide Range

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 a Edwards controller or directly integrated into the vacuum system controls.
