Sensor installation in the flow-through unit

CAUTION
Pinch hazard. Only qualified personnel should conduct the tasks described in this
section of the manual.

Refer to Figure 5 for the installation of the sensor in the flow-through unit.

1. Install the orientation screw to the sensor (Figure 3, item 3 or Figure 4, item 3) to
make sure the measurement path in the measuring chamber is adjusted correctly.

Note: Replace the installed standard 50 mm sensor wiper with the supplied wiper with bore
wholes.

2. Insert the sensor (Figure 5, Figure 6) into the flow-through unit. Turn the sensor so
that the orientation screw slides into the cavity of the panel. Tighten the setscrew
(Figure 3, item 1 or Figure 4, item 1) to the sensor.

3. Connect the inflow and the outflow tubes (Figure 5, Figure 6). Insert the inflow tube
approximately 50 mm into the screw connection of the 2 and 5 mm sensors.

4. Use the allen key to seal the sensor to the measurement chamber.

Note: Remove the inflow tube before disassembling the 2 or 5 mm sensors.
