electrical cable manufacturers junction boxes electrode engine oil temperature sensor erosion-resistant resistant thermocouple

Basic Info

Model No.: erosion-resistant thermocouple

Product Description

  1. Specifications 


    The k type Thermocouple is composed of the two different conductors, and the two ends of them can form the loop. The thermo current will be formed when the temperature differs from each other between the two connections. Simultaneously, the display instrument will show the temperature as to the thermo current accordingly.

    The basic composing stucture will be the same across so many different thermocouples, including the thermode, insulation sleeve, junction box and so on.

    The shape of various thermocouples will differ from each other by the customer needs and application.
