Thermocouple temperature compensation is what _ instrument
Thermocouple temperature compensation as a result of the thermocouple materials are generally more expensive ( Especially when using precious metals) And temperature measuring points are far away the distance to the instrument, in order to save thermocouple materials, reduce cost, usually adopt the compensating conductor (of the cold junction of the thermocouple The free end) Reaches to the relatively stable control indoor temperature and connected to the meter terminals. It must be pointed out that the role of the thermocouple compensation wire only extend thermal electrode, make moves to the control room of the cold junction of the thermocouple meter terminal, it itself does not eliminate the cold end temperature change on the influence of temperature, no compensation. So, still need other correction method is used to compensate the cold end temperature t0 indicates influence on measuring temperature 0 ℃. Must pay attention to when using thermocouple compensating conductor model match, cannot be wrong polarity, compensation conductor should be connected to the thermocouple temperature difference should not exceed 100 ℃.
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.
