Pressure Measurement & Control


Heavy-duty pressure switch

July 2018 Pressure Measurement & Control

From pumps through hydraulic systems to autoclaves, WIKA’s new model PSM-550 heavy-duty pressure switch has been designed for superior industrial applications.

The new instrument switches electrical loads up to AC 230 V/10 A with a non-repeatability of the switch point of 1%. The high accuracy ensures that the machine operates optimally and hence safeguards the quality of the manufactured products.

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 … 0 bar and -0,8 … 5 bar). It is thus also suitable for monitoring vacuum circuits, such as with cleaning processes. The robust instrument has an ingress protection of IP67. Furthermore, the PSM-550 comes in a version for medium temperatures up to 170°C, which has wetted parts from stainless steel.
