Measurement and process compatibility
Measurement range is not an accuracy guarantee across the whole span. These gauge principles are gas dependent; retain the manufacturer’s gas correction and accuracy conditions. Protect the sensing element from unsuitable contamination and choose materials for the process. Bakeout to 150 °C requires removal of the electronics.
The nitrogen accuracy specification is less than 30% of reading from 10⁻⁹ to 10⁻³ mbar and less than 15% from 10⁻³ to 10 mbar. The combined sensors extend coverage to atmosphere without making those accuracy limits valid at every pressure.
Analogue, digital and controller selection
Analogue RJ45 versions and RS232/RS485 D-sub versions are distinct configurations. Connector shape, transfer function, supply and set-point option must all match the receiving controller. The listed standard analogue builds can be selected with compatible Edwards gauge controllers; confirm compatibility for the complete gauge/controller pair. Gauges, cables and controllers are separately specified.
State the pressure range, gas species, flange, output, cable length and calibration requirement. See vacuum gauge calibration for ongoing measurement support.
