Model 240

---

The Model 240 carries global certifications from CSA, UL, and ATEX. The diaphragm isolated Differential Pressure Switch is CSA Certified to both the Canadian and U.S. Standards and U.L. Listed to the U.S. Standards. In addition, it is certified to the ATEX directive Ex d, IIB + H2  with an IP 65 rating.

Mid-West Instrument’s new Hazardous Locations “Delta P” switches are provided with a field wireable terminal strip.
