产品详情介绍

Mid-West 240 系列隔爆差压表带限位开关和变送器
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 + H₂with an IP 65 rating.
Mid-West Instrument’s new Hazardous Locations “Delta P” switches are provided with a field wireable terminal strip. The terminal strip eliminates the need to add a costly explosion-proof junction box near the switch. Multiple outputs are available ranging from low power reed switches to higher load switching relay outputs.
