Assembly K E J B R S type Thermocouple RTD Temperature sensor water
proof
1) Thermocouples are used in industry for measuring the temperature
of gases, liquids or solid surfaces etc.,
2) Its usually assembled with indicators, recorders or computers. A
thermocouple consists of two dissimilar metals joined together at one end. When the junction of the two
metals be cooled or heated and a voltage is produced that can be correlated back to the temperature.
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.
Specification:
Type J (iron–constantan) has a more restricted range than type K
(−40 to +750 °C), but higher sensitivity of about 55 µV/°C.
The Curie point of the iron (770 °C) causes an abrupt change in the
characteristic, which determines the upper temperature limit.
