The WIKA PSM-550 pressure switch can switch electrical loads up to 230 VAC, 10 A with a non-repeatability of the switch point of ≤1%.
The pressure switch can be delivered both with setting ranges for gauge pressure (0–300 mbar to 10–30 bar) and with vacuum setting ranges (-1 to 0 bar and -0.8 to +5 bar).
It is therefore also suitable for monitoring vacuum circuits, eg, in cleaning processes. The robust instrument has an ingress protection of IP67. There is also a PSM-550 version for medium temperatures up to 170°C, which has wetted parts constructed from stainless steel.
The PSM-550 pressure switch has been designed for use in heavy-duty applications from pumps and hydraulic systems through to autoclaves.
