PT100 (terminals 23+ and 11-)
Connection for temperature measurement.
When commissioning the container probe, connect the 4-core
cable of the PT100 to the connector strip of the evaluation (see
fig. 4-8). Connect the other end of the cable with the corre-
sponding plug on the container probe (see fig. 4-6).
In the delivered state, the PT100 cable has a length of 10
meters. We recommend shortening the cable to the required
length.
Combine the two core pairs in accordance with figure 4-8.
After connection of the PT100 cable, the included ferrite core
must be wound around the cable. The applicable position is
within the housing, as close as possible to the cable bushing.
