Temperature sensors and pockets Application A temperature sensor pair is used together with the electronic energy meters for the measurement of inlet and outlet temperatures. Depending on the type, the sensor pairs can be used directly in the fluid flow or installed in a pocket. The temperature sensor has a built-in platinum resistance of which the electrical resistance changes with temperature. A measurement of the resistance value is thus an analog expression of the temperature. An energy meter calculates the differential temperature of a heat installation on the basis of the measurements...
