Overview
Electronic vacuum switches for pressure thresholds in plant control. Piezo and Pirani versions serve different pressure regions and should be selected around the required switch point.
Selection and installation
Provide the setpoint, reset requirement, gas, supply and relay load. Piezo versions have model-specific upper limits; confirm the selected range and switching logic in the quotation.
Questions about this instrument
Does the gas affect the switch point?
It can affect a Pirani sensor because that principle depends on gas thermal conductivity. Supply the process-gas details when setting up the application.
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 vacuum gauge controllers and analogue vacuum transducers. 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.
