9.3.2 Electrical connection
The two matched two-wire sensors are mounted in connection terminals 5 and 6 (t1) as well as 7 and 8 (t2). The
polarity of temperature sensors t1 and t2 is without importance for the functionality.

9.3.3 Pt500 direct short sensor set
TemperatureSensor 63 direct short DS 27.5 mm temperature sensor has been designed according to the European
standard for heat energy meters EN 1434-2. The temperature sensor is designed for direct mounting in the
measured medium, i.e. without sensor pocket, by which a particularly fast response to temperature changes in, for
example, utility water exchangers is obtained. The temperature sensor tube has a diameter of ø3.5 mm, is made of
stainless steel and the temperature sensor element itself is placed in the tube. The temperature sensor is approved
for both PN16 and PN25 installations, with PS25 as the maximum pressure. The temperature sensor is based on a 2-
wire silicone cable and can thus be used with media temperatures up to 150 °C. One of the temperature sensors is
mounted in the flow sensor on delivery and therefore, only the other temperature sensor must be mounted. As
shown in Figure 14 and Figure 15, this can, for example, be made with a nipple or a ball valve.
