FAQ
What is an electronic pressure switch?
Electronic pressure switches are based on electronic pressure sensors, which not only determine whether a setting switch point has been reached, but also transmit the actual measured pressure. it often feature a display from which pressure measurements can be read, as well as flexible settings and programming. Switching point, output signal, delay time, hysteresis and many other parameters can be individually adjusted to suit your application.
What’s the Max Load of the pressure controller?
Limited by contact capacity, AC220V 3A or DC24V 3A, If the capacity of the load is more than the restriction, a extra contactor is necessary.
How to Calibrate a Pressure Switch?
For pressure switches, Accurate calibration is a critical step in ensuring process quality and the safe operation of equipment. The setup is similar to pressure gauge calibration, except now a voltage or continuity across a set of switch contacts needs to be read either by a (Digital Multimeter) DMM or the calibrator.
