Active Pirani Vacuum Gauge

Edwards Active Pirani Vacuum Gauge

APG100 series Active Pirani vacuum gauges are available in 2 models. The APG100-XM is the standard model and measures to 10⁻³ mbar, the APG100-XLC is a corrosion resistant version with measurement to 10⁻⁴ mbar.

Both gauges feature compact size for easy installation, a linear output and a replaceable sensor tube. These gauges are compatible with all Edwards TIC instrument controllers and other Active gauge controllers and displays.

Sensor tube can be baked to 150°C

Adjustable set-point for simple process control and interlocking

Remote calibration possible

NW16,NW25 and DN16CF flange options for easy connection to vacuum systems

Linear output

1 V per decade for easy interface with vacuum control systems.

Features and benefits

• Cable connections and gauge adjustment conveniently located, thereby minimising the space envelope required for access.
