Mechanical pressure switches – standard
If, with a mechanical pressure switch, the defined pressure is reached and the switch is actuated, the switch will send an electrical signal. For this, it needs no auxiliary power. The resulting reliability is one of the advantages of mechanical pressure switches.
Pressure switches are fitted with high-quality micro switches. They feature high long-term stability and precision. Even the switching of electrical loads up to 15 A/220 V is possible without problems with a mechanical pressure switch.
Electronic pressure switches
An electronic pressure switch is based on an electronic pressure sensor. Along with the electrical signal for switching the electrical circuit, many electronic pressure switches offer an additional analogue signal proportional to the pressure. Thus, not only is it identified whether the defined switch point has been reached, but the actual measured pressure is transmitted. Electronic pressure switches often feature a display from which the measured pressure can be read, while flexible settings and programming are also possible. Switch points, output signal, delay time, hysteresis and many other parameters can be individually adjusted to suit the application.
