Sensor for Metal Detecting Sensor

Sensor for Metal Detecting Sensor
Product Detailed
Sensor for Metal Detecting Sensor with high accuracy ISO9001 Pt-Rh wireMax. Temp. range:1820CThermocouple sensor Sensor for Metal Detecting Sensor1. 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.
