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
  • Automatic vacuum setting of Pirani gauge element
  • Unique striker design ensures rapid striking even at high vacuum or in contaminating conditions
  • Low external magnetic field version (L) for sensitive analytical instruments (patented)
  • Serial communications 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
  • Adjustable open collector set-point output for straightforward process control and interlocking
  • NW25 flange for easy connection to vacuum systems – other flange options on request
  • CSA and C/US approved, meets the safety requirements for electrical equipment for measurement
  • RS485 or RS232 versions
  • 9600 to 38400 baud, 8bits, 1 start bit, 1 stop bit, no parity
