    Characteristics of wzpk-231 armored thermal resistance
    ·The thermal response time is less and the dynamic error is reduced;
    ·Small diameter and unlimited length;
    ·High measurement accuracy;
    ·Imported thin film resistor element, reliable and stable performance;
    Working principle of wzpk-231 armored thermistor
    The armored thermal resistance measures the temperature with the characteristics that the resistance of the material changes with the change of temperature. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value.
    Main technical parameters of wzpk-231 armored thermal resistance
