OMEGA’s M12 Thermocouple and Pt100 sensors have been designed for ease of installation and maintenance. Termination is achieved through a polarised M12 connector with a hand-tightened knurled nut completely eliminating wiring errors and, as no tools are required, downtime for a sensor change is drastically reduced.
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.
Having a vibration resistant construction, low probe mass and an ingress protection rating of IP67 the sensors are suited to a broad application range. Typical users include 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.
They are available off-the-shelf with either a stainless steel or Inconel sheath in both 3mm 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.
