Cable specification
If the transmitter is mounted separately from the sensor, the
following cables must be used:
Electrode cable and field coil cable
as shielded twisted pair. In order to protect the cable from ex-
ternal interference, the twisted-pair wires are covered by an
additional, overall shield.

cross section
Example
≤ 10 m
≥ 0,25 mm²
LIYCY-CY TP 2x2x0,25 mm².
> 10 m
≥ 0,75 mm²
SLIYCY-C11Y (2x(2x0,75 mm²)).
The outer shield is groundet by means of special EMC-compliant
cable glands at both ends of the cable.
Wiring diagrams
Connection of the signal cables
•
Lay the signal cables separately from cables with voltages >
60 V.
•
Only use signal cables as specified in chapter „Electrode cable
and field coil cable“.
•
Avoid laying signal cables close to large electrical installations
or use – if possible – only shielded cables.
•
A load at least 250 Ω must exist in the signal circuit for error
free communication via the HART
®
protocol.
