Maintenance & Procedures
7.6.5 Replacing the Trace Moisture Sensor
•
Locate the sensor unit within your ana-
lyzer.
• Open the fittings, connecting the unit to
the piping.
• Only loosen the small nuts (do not remove
them), fixing the sensor unit to the analy
-
zer plate and carefully take the unit out of
the analyzer.
•
Take off the signal plug at the sensor's end
(it is fixed by a screw!).
•
Place a wrench (size: 27 mm) at the hexa-
gon and screw out the sensor by turning
it counterclockwise (ccw).
Do not use the cylindric sen-
sor body to losen the sensor!
Place a second wrench with
size 30 mm from the top to
counterhold the block.
•
Take the new sensor and carefully place
the HDPE protected end of the sensor into
the sensor block.
•
Place the one wrench at the hexagon, the
other at the block to counterhold and fix
the sensor by turning it clockwise (cw).
To ensure proper measure-
ments, apply a torque of
min. 30.5 Nm (269 in.lb).
Do not use the cylindrical sen-
sor body to install the sensor!
• Install the connector to the sensor and fix
it with the screw.
• Place the unit into the analyzer and fix it
with the small nuts.
• Re-install the piping fittings.
•
Make sure that all the plugs associated
with the sensor are properly connected
the same way as before.
