The temperature of water in the heating system (e.g. the output water of the heating source, the temperature of water in the solar system, etc.) is measured by contact temperature sensors; there is available a contact sensor fitted with the Pt1000, P15PA, which should be connected to the analogue inputs of the system. The sensor is designed to measure the surface temperature of piping and it is placed in a plastic head with a terminal block. The module includes a metal holder with a fastening tape for the piping. The sensors are used in a standard environment, where they are not exposed to aggressive chemicals. The sensor is supplied with a silicone 2 m-long cable.
