For the remote sensor, there
is a terminal box in its tapping
(see figure 21). The sensor
should be connected to the con-
verter using a double shielded
cable. You can use our special
sensor cable
PAAR-LiYCY-CY
[1X(2X0,25 LiYCY)+1X(2X0,75
LiYCY)+1X0,75]CY
(length up
to 200 m) or standard double
Maximum length of the cable
between evaluation unit and the
sensor is significantly limited by
conductivity of measured fluid,
as shown in Figure 23.
Remote version should be used
when measured fluid is too hot
to avoid heat transfer to con-
verter. See Figure 24 for as-
sessment of remote version
utilization.

Fig. 21: Sensor terminal box Fig. 22: Remote sensor connection
signal wires is highly inappropri-
ate; especially in case of the
cable that connects the sensor
with the remote converter. If the
instrument is used in environ-
ment with strong electromag-
netic interference, cables
should be rather as short as
possible.
For connection of electronic
converter input and output ter-
minals, shielded cables are suit- able.
For connection of mains volt-
age, a standard three-core ca-
ble, e.g. CYKY 3x1,5 (wire) or
VM03VQ-F 3x1 (wire strand) is
recommended. The instrument
has no switch so it should be
fused and switched using other
device.
