Gauge Indirect Pressure Measurement
Indirect braod range vacuum gauges are the best choice when the pressure needs to be measured over a wide range and when good accuracy is needed across the whole range. Reliable vacuum gauges are essential to ensure your system’s accuracy and control. Our vacuum gauging solutions include the WRG Series Cold Cathode Combination Gauge, AIM Series Cold Cathode Gauge, and APG Series Pirani Gauge.
nWRG Series (digital)
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 RoHS compliant due to their lead-free construction.
Features and Benefits
- Wide-range supply voltage allows operation from 15 to 48V d.c.
- Gauge naming allows user to store gauge identification data
