12.2 MOUNTING OF THE SENSOR LA 1S INTO THE UNIVERSAL FILTER
In case the client has selected single components, the mounting of the sensor has to be effected as
follows:

Dismount the red GL25 union nut incl. the inside GL25-12 clamping ring from the filter.

Tear the red anti-kink socket of the cable on the sensor LA 1S by slight swinging movements
backwards in direction of the connection cable of the sensor body.

Push the GL25 union nut on the sensor body with its inside thread showing to the sensor
beginning (platinum electrodes) backwards in direction of the red cable anti-kink.

Push the GL25-12 clamping ring with the white PTFE surface showing to the sensor beginning
(medium side) over the swelling on the sensor body.
N O T E !
The PTFE/Silicone clamping ring GL25-12 must not be defective. Only then,
the necessary tightness is guaranteed.

Push the red union nut with clamping ring against the swelling on the sensor body.

Push the red anti-kink socket of the cable by slight swinging movements onto the sensor body
again.

Screw the red GL25 union nut with sensor onto the GL connection thread of the filter.
12.3 MOUNTING OF THE SENSOR LA 1S INTO THE FLOW CHAMBER LS
If the client has selected single components, the mounting of the sensor has to be effected as follows:

Dismount the union nut incl. the inside O-ring and the pressing ring from the chamber body.

Tear the red anti-kink cable socket by slight swinging movements from the sensor body over
the connecting cable.

Push the union nut with its inside threading showing to the sensor beginning (platinum
electrodes) over the connection cable onto the sensor body.

Push the PVDF pressing ring and afterwards the black FPM O-
ring on the electrodes’ side up
to the swelling on the sensor body.
N O T E !
The O-ring must not be defective. Only then, the necessary tightness is
guaranteed.

Push the union nut on the sensor body up to the swelling.

Put the sensor connection cable again through the black anti-king cable socket and push the
socket by slight swinging movements approx. 15 mm onto the sensor body.

Mount the sensor with union nut into the below connection of the flow chamber.
