Thermocouple industry standard

(1) The thermocouple is a kind of basic temperature sensor. Because it is widely used in various industries, it should be based on the use of the industry, the measured medium, the measured temperature, the installation site, the surrounding environment, etc. consider.

(2) The model of the thermocouple generally determines the common performance, technical parameters and using conditions of the product, but it also needs to provide more comprehensive parameters when ordering; this is conducive to selecting the most commonly used technical parameters for the products that are most suitable for their own use. as follows:

(1): Thermocouple Model:

a: Usually: WR letter beginning b: Special symbol (2): Index number:

a: Common K, S, B, R, E, J, T, etc. b: Special index number (3): Accuracy class a: Class I b: Class II c: Class III (4): Temperature range:

a:usual temperature:-20-+1800°C

b: specific temperature (5): material a: metal: commonly used 304, 310, 316, GH, HC,

b: Non-metals: ceramics, compounds, composite pipes, etc. (6): Dimensions:

a: Diameter of thermocouple protection sleeve (φ:mm)

b: total length (L:mm)

c: insertion depth (I:mm)

(7): Installation connection:

a: no fixed b: thread (bolt)

c: flange (8): electrical interface type a: junction box type b: compensation line (soft wire) type c: connector (9): temperature measurement element form a: single b: double c: multiple pairs ( More)

(10): Temperature measuring head type a: Shell type b: Insulative type c: Outcrop type
