What are the different thermocouple types?

Thermocouples are available in different combinations of metals or calibrations. The four most common calibrations are J, K, T and E. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple.

How do I choose a thermocouple type?

Because thermocouples measure in wide temperature ranges and can be relatively rugged,they are very often used in industry. The following criteria are used in selecting a thermocouple:Temperature range Chemical resistance of the thermocouple or sheath material Abrasion and vibration resistance
Installation requirements (may need to be compatible with existing equipment; existing holes may determine probe diameter).

1. JIS C1602 – 1995 IEC 584-2-1982 (Amendment 1 – 1989) BS/EN 60584-2-1993 DIN/IEC 584-2-1992 Note: 1. Tolerance denotes the maximum allowable value obtained by subtracting the temperature reading or the temperature at the hot junction from the standard temperature converted from the applicable temperature EMF table. 2. Tolerance Class 1 for Type R and S only apply to the Standard or Refence thermocouple. 3. │t│denotes the value of temperature (°C) irrespective of positive (+) or negative (-) sign. 4. Tolerances listed in this page apply to the new thermocouple wires. • not standardized yet by JIS 2.

What is Thermocouple?

图片
A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created.  There are many types of thermocouples, each with its own unique characteristics in terms of temperature range, durability, vibration resistance, chemical resistance, and application compatibility. Type J, K, T, & E are “Base Metal” thermocouples, the most common types of thermocouples.Type R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature applications. Thermocouples are used in many industrial, scientific, and OEM applications. They can be found in nearly all industrial markets: Power Generation, Oil/Gas, Pharmaceutical, BioTech, Cement, Paper & Pulp, etc. Thermocouples are also used in everyday appliances like stov
