Rapid-response type expendable thermocouple 1. The rapid consumption of thermocouple
 Disposal /thermocouple thermocouple (also called expandable thermocouple or The rapid consumption of  thermocouple) is a sensor for temperature measurement. It can be connected to a fast potentiometer or a digital instrument to measure temperatures of melted iron, steed or other metals. Pt-Rh Expendable thermocouple (Type S,R,B) is usually connected with display meter,recording meter and computer,etc.to directly measure temperature of liquid meteal ranging from 0-1820 during various steel or iron process.
It has advantage of high accuracy,rapid reaction,reliability and stability. Structure of thermocouple     Note: 1Protective iron/Al cap 6 refractory cement head or refractory ceramic head   According the different thermocoupe wire,thermocouple has four type are S,R,Band WRe Type.
