Equipment combinations
All systems or devices capable of acquiring and handling the sensor's passive output signal.
Notes
Engineering
Protection pockets made of Brass may not be used with nominal pressures over PN 10 or at
temperatures over 130 °C. For higher nominal pressures or temperatures up to max. 135 °C
the protection pocket is to omit (max. PN 16) or a protection pocket made of stainless steel
(V4A) is required (see table accessories).
Mounting and installation
Depending on use, the sensor should be located as follows:
● For flow temperature control (in the heating flow):
– Directly after the pump if the pump is located in the flow
– 1.5 to 2 m after the mixing valve if the pump is located in the return
● For return temperature limitation:
In the return at a location where the temperature can be correctly acquired
The sensor should be installed in an elbow with the immersion rod or the protection pocket
facing the direction of flow. The water must be well mixed where the temperature is acquired.
This is downstream from the pump or, if the pump is mounted in the return, at least 1.5 m
after the mixing point.
The sensor should be mounted such that the cable does not enter from the top.
With all types of sensors, the immersion length must be a minimum of 60 mm!
The sensor must not be covered by lagging.
To fit the sensor, a threaded fitting or T-piece G ½ must be welded into the pipe.
