K type Thermocouple with Connector TD plugs SR type Ceramic Plastic
Introduction
1.A thermocouple is a temperature-measuring device consisting of
two dissimilar conductors that contact each other at one or more
spots.
2.It produces a voltage when the temperature of one of the spots
differs from the reference temperature at other parts of the
circuit.
3.Thermocouples are a widely used type of temperature sensorfor
measurement and control,and can also convert a temperature gradient
into electricity. Commercial thermocouples are
inexpensive,interchangeable, are supplied with standard connectors,
and can measure a wide range of temperatures.
4.In contrast to most other methods of temperature measurement,
thermocouples are self powered and require no external form of
excitation.

Application
Thermocouples are widely used in science and industry;
Applications include temperature measurement for kilns, gas turbine
exhaust, diesel engines, and other industrial processes.
Thermocouples are also used in homes, offices and businesses as the
temperature sensors in thermostats, and also as flame sensors in
safety devices for gas-powered major appliances.
