Overview

The Digital Wide Range Gauge (nWRG) 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 a Edwards controller or directly integrated into the vacuum system controls.

Features and Benefits

·       Digital interface removes need for Controller as can connect directly to PC or PLC

·       Magnetron uses an advanced patented technique for highly reliable striking, even at high vacuum or in relatively contaminated conditions

·       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
