The M-BLK variant features a 1\/4\" FNPT mounting port for straightforward integration into standard refrigerant lines. Rated for an operating range that typically spans from 20 inHg to 100 psi, this device uses a straightforward open-low switch action to energize or de-energize the circuit as pressure drops. Part of the P70 family of controls, the P70GA-27 is commonly used to safeguard compressors and evaporators in commercial and industrial systems, where maintaining adequate low-side pressure is critical to prevent motor stall or damage. A closely related P70GA-27C variant is described as Temperature\/Process Control, reflecting the family’s broader role in temperature and pressure protection across refrigeration and process cooling installations. Typical applications include evaporator protection in refrigeration systems and air-conditioning setups, where a reliable, durable control point helps prevent underpressure conditions from impacting performance.\u003c\/p\u003e\u003c\/div\u003e","brand":"Chromalox","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678027677998,"sku":null,"price":434.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_74296c80-b271-444c-9a8e-110390aeab84.jpg?v=1769570813","url":"https:\/\/plgautomation.com\/products\/johnson-controls-p70ga-27-industrial-temperature-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
