8.3 Pocket sensors
The Pt500 cable sensor is constructed with 2-wire silicone cable and closed with a D 5.8 mm shrunk on stainless
steel tube, which protects the sensor element.
The steel tube is mounted in a sensor pocket (immersion pipe) which has an inner diameter of 6 mm and an outer
diameter of 8 mm. Sensor pockets are available with R½ (conical ½”) connection in stainless steel i lengths of 65,
90 and 140 mm. The sensor construction with separate immersion pipe permits replacement of sensors without
having to switch off the flow. Furthermore, the wide range of immersion pipe lengths ensures that the sensors can
be mounted in all existing pipe dimensions.

The stainless steel pockets can be for mounting in PN25 systems!
The plastic tube on the sensor
cable is placed opposite the
sealing screw and the screw is
tightened lightly by hand before
sealing.
