  • Product Description
    • Commodity name: 2510Temperature transmitter

    The working principle of temperature transmitters is mainly based on the thermoelectric and resistive effects.
    Thermoelectric effect: The difference in thermoelectric potential of different materials is used to measure temperature. Common thermocouples and RTDs are made based on this principle. Thermocouple by two different components of the conductor or semiconductor made of closed circuit encapsulated in a metal or semiconductor protection tube, when the thermocouple temperature difference between the two ends of the existence of the thermopotential difference, will produce thermoelectric potential difference, through the measurement of this thermopotential difference can get the temperature value.
    Resistance effect: Using the effect of temperature on the resistance value to measure the temperature. For example, the resistance value of a thermistor changes with temperature, and the temperature value can be deduced by measuring the change in resistance value.
    Temperature transmitters contain temperature-sensing elements (such as thermocouples or RTDs) and signal processing circuits inside. When the temperature of the measured medium changes, the temperature sensing element will produce a corresponding signal change, the signal through the signal processing circuit for regulator filtering, operational amplification, non-linear correction, V / I conversion, constant current and reverse protection and other processing, converted to a linear relationship with the temperature of the standardised output signal (such as 4 ~ 20mA current signal, 0 ~ 5V / 0 ~ 10V voltage signal or RS485). digital signal).
