The flexible lead wire nb1 replacement probe is ideal for field installation. The type k is the most common type of thermocouple. The type e has higher stability when compared to type k thermocouple due to. The nicrosilnisil thermocouple is ideally suited for accurate measurements in air up to 1200c. Belden thermocouple extension wire type determines the conductor material. The type n thermocouple has a nicrosil nickel14% chromium 1. Instrumentation cable for processing industries in ref. Its sensitivity of 39vc at 900c is slightly lower than type k 41vc. Type k chromelalumel is the most common generalpurpose thermocouple with a. Mi cable helps to protect the thermocouple wire from corrosion and electrical. Thermocouple extension and compensating cables codes. K type thermocouple extension wire omega engineering.
Type k thermocouples should not be used in sulphuric environment since both elements will rapidly corrode and the negative element will eventually fail mechanically due to becoming brittle. Thermocouplethermocoupleswhat is a thermocoupletypes of. Type k, like type e should not be used in sulfurous atmospheres, in a vacuum or in low oxygen environments where selective oxidation will occur. In addition, stock consists of tray cable approved as well as. Type k thermothal pthermothal n is made with two alloys of high nickel content which allows their use in both oxidizing and reducing atmospheres. Thermocouplesthermocouple types j, k, e, t, n, b, r, s. The type k is commonly found in nuclear applications because of its relative radiation hardness.
Thermocouple types types of thermocouples comparison. Interchangeability tolerances are the same as for type k. Extension and compensating cables, paired catalogue lapp. In vacuum or controlled atmosphere, it can withstand temperatures in excess of 1200c. They are mostly used for applications at temperatures above 550 c up to the maximum working pressure of the thermocouple. Type kx thermocouple extension cable conductors are made from the same constituent elements as the type k thermocouple combination and therefore. A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming. Thermocouples thermocouple types type j thermocouple, type k thermocouple, type e thermocouple, type t thermocouple, type n thermocouple, type b thermocouple, type r thermocouple, type s thermocouple. Possible module types are shown in the table below. The temperature range for type k is 330 to 2300 f and its wire color code is yellow and red. Kanthal alloys for thermocouple, extension and compensating cables. For more detailed information, see appendix t8 and data sheets. Thermocouple cable texcan stocks thermocouple cables in shield, nonshield, armoured, nonarmored, stranded as well as solid pairs complete with a variety of insulations and jackets.
