How to deal with _ instrument thermocouple common failure
Thermocouple is a kind of common temperature measuring instrument, the scope of application is also very extensive. Thermocouple common failure 1, failure 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: correct wiring, or find out short circuit, reinforced insulation. 2, fault phenomenon: thermocouple table indicating infinity; Possible reasons: thermocouple or loosen the lead wire short circuit or terminal; Methods: the change in resistance or welding and tighten the screw connection, etc. 3, fault phenomenon: display of thermocouple 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. 4, failure phenomenon: thermocouple value changes with the temperature relation; Possible reasons: thermocouple wire material corrosion 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.
