Thermocouples with unified 4-20 mA output THAU-001, THKU-001, TJKU-001

Thermocouples (thermoelectric converters, temperature sensors) THAU-001, THKU-001, TJKU-001 are designed to convert the temperature of the working end of the thermocouple into thermo-EMF. Thermoelectric converters are used to measure the temperature of liquid, bulk, and gaseous media that do not contain substances interacting with the material of the protective fittings and connecting cable. The application area of thermocouples is temperature control and regulation systems of technological processes in various industries, agriculture and utilities, household. The principle of operation of the thermocouple is based on the thermoelectric Seebeck effect Seebeck. The thermocouple has two welded ends: one end is placed in the measured medium and is called the working or hot junction, and the other at the connection point to the device input is the cold junction. When a temperature difference arises between the hot and cold junctions, a thermo-EMF appears in the circuit, the value of which is fed to the input. The working junction is placed in protective fittings. Main technical characteristics of 4-20 mA thermocouples Operating temperature range, depending on thermocouple type — (0-1100) °C; Ambient temperature range around the 4-20 mA converter board — from 5 to 55 °C; Connection scheme of the measuring element — two-wire; Thermocouple type with 4-20 mA output — K (THAU-001), L (THKU-001), J (TJKU-001); Protective fittings material — stainless steel 12x18H10T; Degree of protection against dust and water — IP54; Design — non-disassemblable; Insulation resistance — not less than 100 MOhm; Output signal — 4-20 mA; DC power supply voltage — 9-36 V; Power consumption current, maximum — 40 mA; Maximum allowable basic error — no more than 0.5%; 1% (regulated at 25 °C for operation of the 4-20 mA converter board). You may be interested in thermoelectric temperature converters with a unified 4-20 mA output signal (modification 002) THAU-002, THKU-002, TJKU-002, which unlike modification 001 have a movable or welded fitting for mounting in a sleeve or screwing into a boss. Full designation of thermocouples for ordering: REGMIK-PTU-THAU-001, REGMIK-PTU-THKU-001, REGMIK-PTU-TJKU-001.
