Pressure switches are used in a variety of industrial and technical processes. If a preset pressure is reached, then the pressure switch opens or closes a respective switch contact. Depending on the requirements, mechanical or electronic models can be used.
In WIKA's broad product range, you will find the right pressure switch for every application:
What are 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.
WIKA 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 from WIKA.
For the switching of very low voltages, such as those used in PLCs, WIKA offers argon gas-filled micro switches with gold-plated contacts. Electronic pressure switches are also very well suited for low-power switching.
Mechanical pressure switches - explosion-protected
For operation in hazardous areas, WIKA mechanical pressure switches are available in Ex-ia or Ex-d variants. The Ex-d approved switches are available in epoxy-resin coated cases made from copper-free aluminium.
What are 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.
The successful design and the excellent functionality of the WIKA switch family were already confirmed by winning the “iF product design award 2009” for the model PSD-30. As a comprehensive further development with additional functions, the model PSD-4 electronic pressure switch is also notable.
