SUP-WRNK thermocouples sensors is mineral insulated construction which results in thermocouples wires that are surrounded by a compacted mineral insulation (MgO) and contained in a sheath such as stainless steel or heat resisting steel. On the basis of this mineral insulated construction, a wide variety of otherwise difficult applications are possible. Features Sensor: B,E,J,K,N,R,S,TTemp.: -200℃ to +1850℃Output: 4-20mA / Thermocouple (TC)Supply:DC12-40V
