Active Pirani Gauge

Active Pirani Gauge
  • Wide-range supply voltage allows operation from 15 to 48V d.c
     
  • Sensor tube can be baked to 150°C
     
  • Remote calibration possible
     
  • NW16,NW25 and DN16CF flange options for easy connection to vacuum systems
     
  • Adjustable open collector set-point output for straightforward process control and interlocking

Edwards nAPG series, active Pirani vacuum gauges is available in 2 models. The nAPG-M is the standard model and measures to 10-3 mbar. The nAPG-LC is a corrosion resistant version with measurement to 10-4 mbar.

Both 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 leadfree construction.
