Replacement WGM701 Sensor Assembly DN40CF

The WGM701 Wasp is a vacuum gauge module with an inverted magnetron cold cathode technology with a pirani sensor. Constructed with a compact metal design, the sensor assembly features a sensor activation aid for improved cold cathode sensor activation time.

The ultra-low magnetic stray field design makes it compatible with instruments sensitive to external magnetic fields, and its interchangeable dual chamber design reduces maintenance, offering a robust vacuum gauge.

The WGM701 provides essential signal conditioning and a built-in controller with log-linear analog output and sensor status output, automatically activating the Cold Cathode sensor once the pressure measured by the Pirani sensor has indicated a low enough pressure level of 9.10e-3 mBar
