4.5 Installing the sensor

When installing the sensor, observe the following points:

— Installation in the pipe component or welding adapter is

only possible if the sensor data matches the measuring

point specifications.

— The sensor may be sealed only by using the O-ring supplied

in the scope of delivery. The O-ring must be placed in the

designated groove on the sensor connection flange.

— The measuring elements may not be damaged when

inserting the sensor into the pipe component.

— If you are using an integrated changing device, you must

check that the changing device is in the disassembly

position before releasing the mounting screws.

Place the supplied O-ring in the groove of the sensor

connection flange.

Carefully slide the sensor into the pipe component. Observe

correct alignment to the centering pin in the process

Fasten the sensor to the sensor connection flange using

screws. Tighten the flange screws simultaneously by
