2.3.1 Temperature sensor

This product is equipped with two PT1000 temperature sensor connection interfaces to provide accurate upstream and downstream pipeline temperature measurements. The measurement function can be used as an extended application of the BTU thermal energy meter. The relevant precautions are as follows:

● Please use a two-wire PT1000 sensor; the product is not compatible with PT500 and PT100 sensors.

● The measuring range of the instrument is -100 ~ 300 °C. The quality and accuracy of the sensor used will directly affect temperature measurement results. Please select the correct, appropriate temperature sensing element.

● The sensor has no polarity, but there is a distinction between upstream and downstream. Care should be taken to note this during installation.

● Wire length should be less than 3 meters. If wires are too long, it will affect measuring accuracy.

● Keep the wires away from any instruments or devices that may generate electromagnetic noise, such as large cables, motors, power strips, inverters, etc. Wire and product connectors must be securely mounted. Weak or loose contacts may result in resistance and affect the measurement results.
