Tolerances on Temperature Reading

图片
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. Tolerance on Temperature Reading To ASTM E 230-1998, E988 – 1996 Note: The above color codes are in accordance with ASTM E 230 – 1998 Contact: thermocouplesupplier@gmail.com

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
