Wide Range Gauge

Edwards Wide Range Gauge

Edwards nWRG series Wide Range gauges offer single port pressure measurement in the range atmosphere to 10-9 mbar. These are new digital versions of gauges that have proved to be rugged and reliable in a wide range of applications ranging from scientific instruments to industrial processes.

The nWRG gauges feature compact size for easy installation, a serial output and a replaceable sensor tube. It is anticipated that the digital gauges will be compatible with the next generation of Edwards instrument and active gauge controllers and displays. They are CSA and C/US approved as well as fully oHS compliant due to their lead-free construction.

Wide-range supply voltage

allows operation from 15 to 48V d.c

Automatic vacuum setting of Pirani gauge element

Unique striker design

ensures rapid striking even at high vacuum or in contaminating conditions

Adjustable open collector set-point output
