For reasons of compatibility, the expression "sensor cable" is used for all
BPG400 versions in this document, although the pressure reading of the
gauges with fieldbus interface (BPG400-SD, BPG400-SP or
BPG400-SR) is normally transmitted via DeviceNet, Profibus or RS485.
The sensor cable is required for supplying all BPG400 types with power.
In connection with the gauges with fieldbus interface (BPG400-SD,
BPG400-SP and BPG400-SR), it also permits access to the relay con-
tacts of the switching functions (
→ 21, 44).
The application and length of the sensor cable have to be considered when deter-
mining the number and cross sections of the conductors (
→ 9).
Open the cable connector (D-Sub, 15 pins, female).
Prepare the cable and solder/crimp it to the connector as indicated in the
diagram of the gauge used:
