Direct short EN 1434 temperature sensor
The direct short temperature sensor has been designed according to the European standard for heat energy meters
EN 1434-2. The temperature sensor is constructed to be mounted directly in the measuring medium, i.e. without
sensor pocket, by which an extremely fast response to temperature changes from e.g. domestic water exchangers is
obtained.
The sensor is based on two-wire silicone cable. The sensor pipe is made of stainless steel and has a diameter of 4
mm at the point where the sensor element is placed. Furthermore, it can be directly mounted in many of Kamstrup’s
flow sensor types, which reduces the installation costs. The direct short sensor is available in a 27.5 mm version, type
DS 27.5 mm, and in a 38 mm version, type DS 38 mm. The direct short sensor can be used in both PN16 and PN25
installations with a maximum medium temperature of 150 °C.

As it appears from
Figure 9
, the direct
short sensor DS 27.5 mm can be
mounted by means of an R½ or R¾ for
M10 nipple in a standard 90
°
tee.
In order to obtain the best possible
serviceability during meter replacement,
the direct short sensor can be placed in a
ball valve with sensor socket, see
Figure 10
.
Ball valves with sensor sockets are available
in G½, G¾, G1, all of which fit the DS 27.5
mm sensor, as well as in G1¼ and G1½,
both fitting the DS 38 mm sensor.
