Platinum Resistance Temperature Sensor For Heat Meter
The precision of each pair of temperature probes after pairing may meet the error of 0.1°C, and each pair of temperature sensors for the heat meter series industrial temperature sensors confirms to the criteria of Chinese standard CJ 128-2007 and European standard EN 1434 in terms of error range. To avoid MIS installation due to the length of the cable, the two ends of the probe are each marked with a red and blue marker. Upper water is at the red end, while lower water is at the blue end.

The heat meter is mainly composed of three parts: flow sensor, paired temperature sensor and calculator. For heat meter series industrial temperature sensors, the error range of each pair of temperature sensors meets the requirements of Chinese standard CJ 128-2007 and European standard EN 1434, and the accuracy of each pair of temperature probes after pairing can meet the error of ±0.1°C, each pair of temperature sensors The two ends of the probe are respectively marked with red and blue to avoid MIS installation due to the length of the cable. The red end is the upper water end, and the blue end is the lower water end.
