Sensor installation
The sensor shaft is equipped with a conical G
mounting thread. The installation of the sensor is made
by threaded bushes or flanges. The process area is
sealed perfectly with flat gasket and an O-ring.
Note: When mounted in-line, the sensor should
be in stalled centered to avoid pipe wall effects. If there is
less than 30 mm (1.18 inch) spacing between sensor

and pipe, a product calibration with a sensor built in
the process is re commended to meet the specified
accuracies.

Note: Proper installation of the sensor is important for
e fficient and accurate operation. For all applications and
sensor configurations, mounting arrangements must be
located so that:
– Sample at the sensing area is representative of the
– Solution circulates actively and continuously past the
– Position and orientation of the sensor does not trap
