JWF offer a wide range of pressure switches from WIKA including mechanical and electrical.
Pressure switches are used for monitoring and direct switching of electrical loads. Setting ranges available from 16 mbar to 600 bar, also all other equivalent vacuum or combined pressure and vacuum ranges. Repeatability of the switch point < 1 % of the setting range. Ex ia & Exd versions available.
The model PSD-4 pressure switch represents the extensive further development of the PSD-30 pressure switch. A high accuracy of 0.5 %, freely configurable output signals (PNP/NPN, 4 to 20 mA/0 to 10 V), the 5:1 scalability of the analogue output, in addition to outstanding self-diagnostics, make the PSD-4 an excellent solution.
