This pressure switch has an adjustable switch differential

By Mary Page Bailey and Gerald Ondrey |

WIKA Alexander Wiegand

The model PSM-700 rugged pressure switch (photo) offers a switch differential adjustable over a wide range, very high repeatability. The PSM-700 has a UL-listed micro switch that switches at electrical powers up to 250 V a.c. and 10 A. With a switch point repeatability of ≤0.5%, it offers long-lasting high reliability, says the company. The high adjustability of the switch differential — up to 60% of the setting range — enables flexible on/off switching. The instrument can be delivered with setting ranges from 1–1.5 to 7–35 bars. A robust aluminum case and wetted parts made of corrosion-resistant 316L stainless steel also enable the new pressure switch to be used under harsh conditions. A dual-entry option is possible for the electrical connection (top and side), which means that the instrument can be mounted in the optimal orientation. — WIKA Alexander Wiegand SE & Co.
