Note
We do not recommend to unscrew the sensor from the sensor
connection cable when cleaning the sensor shaft and membrane.
Otherwise, moisture and/or dirt can get into the plug connection where
they can cause contact problems.
If you would like to disconnect the sensor from the sensor connection
cable, please note the following points:
 Before disconnecting the sensor from the SACIQ (SW) sensor
connection cable, remove any larger pieces of contamination from
the sensor, particularly in the area of the plug connection (brush it
off in a bucket of tap water, wash it off with a hose or wipe it off with
a cloth).
 Unscrew the sensor from the SACIQ (SW) sensor connection cable.
 Always place a protective cap on the sensor plug head connector
and on the SACIQ (SW) sensor connection cable so that no
moisture or dirt can get into the contacting surfaces.
 In corrosive environments, close the socket of the sensor
connection cable with the screwable SACIQ-Plug when it is dry in
order to protect the electrical contacts from corrosion. The protective
plug is available as an accessory (see section 5.3 A
CCESSORIES ). It
is included in the standard scope of delivery of the SACIQ SW
sensor connection cable.
CAUTION
The sensor warms up during operation in the air. Consequently,
pollution can collect in the vicinity of the measurement window
due to the evaporation of liquid. Therefore, avoid any lengthy
operation in the air.
Cleaning
1 Pull the sensor out of the sample.
2 Remove any coarse pollution from the sensor (by brushing it off
in a bucket of tapwater, spraying it off with a hose or wiping with
a cloth).
3 Clean the sensor shaft and the sapphire disc as specified in the
section C
LEANING AGENTS .
4 Then, rinse it thoroughly with tap water.
