Active Pirani Gauge

Edwards Active Pirani Gauge

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.

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

Features and benefits

• Gauge naming allows user to store gauge identification data


• 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

• RS485, 9600baud, 8bits, 1 start bit 1 stop bit For information on Digital Gauge DX protocol please contact Edwards.
