    Tips: How to properly calculate the temperature sensor insertion depth?

    In order to ensure the measurement accuracy, usually, all the sensitive sections of the temperature sensor are inserted into the measured medium. Then the required immersion length of the temperature sensor is:

    1. When measuring gas, the insertion depth of the thermocouple should be more than 95mm, and the insertion depth of the RTD sensor and bimetal temperature sensor should be more than 115mm.
    2. When measuring liquid, the insertion depth of thermocouple, RTD sensor and bimetal temperature sensor should all be greater than 46mm.
    3. Then the insertion depth of temperature sensor = connector + wall thickness + immersion length.
    4. If the diameter of the pipeline is too small (diameter less than 80mm), an enlarged pipeline should be made when installing a temperature sensor.
    5. For the temperature measurement of general tower equipment, when the temperature sensor is installed horizontally, the temperature sensor insertion depth is 300-400mm. For the temperature measurement of the boiler hearth, the temperature sensor is mostly installed horizontally. Except for the thickness of the refractory bricks of the furnace body, just need to insert 150mm into the furnace.
