Vanliga fel och lösningar av temperatursändare

The temperature transmitter is a field-mounted temperature transmitter unit that uses a two-wire transmission method (power input and signal output are two common wires) and outputs a 4-20mA current signal that is linear with the measured temperature. The transmitter can be installed in the junction box of the thermocouple or thermal resistor to form an integrated structure, or it can be installed in the detection equipment as a functional Modul . Termoelementets temperatursändare har funktionen av automatisk kall slutkompensation . Det används ofta inom området industriell kontroll för automatisk upptäckt, transmission och kontroll .}}
Temperaturöverföringsteknologi är mycket mogen och mycket vanlig i olika fabriker . Temperatursändare används ofta i samband med vissa instrument . Det finns ofta några mindre fel under användningen av matchning . De vanligare felen och lösningarna är som följande .}
, the transmitter output does not change when the temperature of the measured medium increases or decreases. This situation is mostly a problem with the sealing of the temperature transmitter. It may be because the temperature transmitter is not sealed well or a small hole is accidentally welded in the sensor during welding. This situation generally requires replacing the transmitter housing to solve det .
För det andra är utsignalen instabil . Detta beror på själva temperaturkällan . Temperaturkällan är en instabil temperatur . Om instrumentdisplayen är instabil, beror det på att instrumentets anti-interferensförmåga inte är stark .
Third, the transmitter output error is large. There are many reasons for this situation. It may be that the resistance wire of the selected temperature transmitter is incorrect, resulting in a range error. It is also possible that the transmitter was not calibrated properly when it left the factory.
It is rare for a temperature transmitter to fail. As long as a careful inspection is carried out before leaving the factory, these situations can be avoided. Therefore, the temperature transmitter must be inspected before leaving the factory. Customers can also ask the transmitter manufacturer for a factory inspection report for reference.
