The tem- perature sensors have built-in platinum resistors of which the electric resistance changes according to the tempera- ture. A measurement of the resistance value thus provides an analogue expression of the temperature. TemperatureSensor 83 can be connected to the calculator with either 2-wire or 4-wire connection. For Tempera- tureSensor 83 with 4-wire connection, it applies that the resistance of the cable does not influence the tempera- ture measurement. By default, this means that a better temperature measurement is achieved than when using 2-wire connection. TemperatureSensor 83 with 4-wire con- nection is thus typically used in large installations where an improved temperature measurement provides greater opportunities for optimising the operational conditions and with it the production costs. At the same time, Temper- atureSensor 83 with 4-wire connection provides greater flexibility with regard to making an optimal cabling as the cables in this case do not need to be equally long. TemperatureSensor 83 consists of a pair of Pt500 tem- perature sensors (insert) and different suitable pockets in lengths 65, 90, 140 and 180 mm. It is thus possible to exchange the Pt500 temperature sensor pair in the instal- lation without turning off the water, because the pocket can remain in the installation. TemperatureSensor 83 is approved for IP68 and is thus especially suited to be used for both heat and cooling measurements. 2 Kamstrup A/S • 58101819_C1_EN_01.2023
