Overview
A mechanical switching option for vacuum systems requiring a defined pressure threshold. Select the switching direction and confirm the pressure reference and electrical load before ordering.
Selection and installation
Provide the desired switch-on and reset pressures, contact load and process connection. The difference between switching and resetting matters when controlling a pump or valve.
Questions about this instrument
Can it switch my pump motor directly?
Send the load and control-circuit details. Contact ratings and the need for an interposing relay or contactor must be checked for the selected switch.
Can I request calibration with my gauge?
Yes. Tell us the operating range, required test points and certificate requirement. We will confirm the calibration option for the selected instrument before quoting. Discuss vacuum gauge calibration.
Which related instruments should I consider?
Compare electronic vacuum switches and vacuum gauge controllers. Check the pressure reference, measurement range and output rather than selecting by connection alone.
Where could this instrument be useful in a vacuum system?
Explore measurement and control requirements for the INDUSVAC centralised vacuum system and LABOVAC laboratory vacuum system. Check existing sensors, controller inputs, switching duties and connection details before selecting an additional or replacement instrument.
Specify your requirement
Send the pressure range and reference (absolute or relative), process gas, connection, quantity and required delivery date. Include the existing model or a photograph for replacement enquiries.
