Thermocouple common fault _ instrument
Thermocouple is a kind of common temperature measuring instrument, the scope of application is also very extensive. Fault phenomenon digital display table indicates a negative; Possible reasons: digital display table with thermocouple wiring is wrong or thermocouple have short circuit phenomenon; Processing method to correct wiring, or find out short circuit, reinforced insulation. Fault phenomenon of thermocouple table indicating infinity; Possible reasons: thermocouple or loosen the lead wire short circuit or terminal; Process change in resistance or welded and tighten the screw connection, etc. Malfunction phenomenon that thermocouple of the indicated value is lower than the actual value or unstable value; Possible reasons: protecting tube with metal dust, dust, dirt and thermocouple short circuit between terminal; Methods: to remove scrap metal, cleaning dust, water, etc. , find the short circuit point reinforced insulation. Fault phenomenon thermocouple value changes with the temperature relation; Thermocouple wire material corrosion may cause metamorphism; Deal with method: replace thermocouple;
During the exhibition season, the company team, with company letter product thermocouple, thermal resistance electronic temperature and other products, visited our company's European and South American customers, meet with old customers at the exhibition, new products are welcomed by old customers; should be invited, visit customer company, deepen The understanding of both sides is for further cooperation.
