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.
allows operation from 15 to 48V d.c
ensures rapid striking even at high vacuum or in contaminating conditions
for straightforward process control and interlocking
based on a simple ASCII, low latency, query and command protocol that can operated in a point to point or multidrop system with minimum overhead
