Featuring a vibration resistant construction, low probe mass and an ingress protection rating of IP67, OMEGA’s M12 thermocouple and Pt100 sensors are available off-the-shelf with either a stainless steel or Inconel sheath in both 3 and 6mm diameter with standard lengths of 200, 500, 750, 1000 and 1500mm. The range is further enhanced by a variety of process fittings including BSP, NPT and metric mounting threads, as well as Tri-clamp flanges for hygienic and vacuum applications. Termination is through a polarised M12 connector with a hand-tightened knurled nut, without requiring any tools, completely eliminating wiring errors. Previously the only options available for cold end termination were traditional in-line plastic connectors or conventional terminal head arrangements where a more permanent, robust installation was required. Those were often supplied with vague IP ratings and a variety of electrical connections requiring additional thread adaptors and termination glands to complete the system. Overcoming all these difficulties, the sensors find typical use in industrial, hygienic, food and beverage, pharmaceutical and research laboratories where process conditions such as outdoor, wet, high humidity, wash-down situations and other challenging environments exist.
