5.1.2 Measuring cables and sensor connection
You require shielded special measuring cables to connect conductivity sensors to the
transmitter. The following multi-core, pre-terminated cable types can be used:
Sensor type Cable Extension
Two-electrode sensor with or without
temperature sensor Pt 100
CYK71
CPK9* (for CLS16)
VBM box + CYK71 cable
Inductive sensor CLS50, CLS52 Fixed cable on sensor VBM box + CLK6 cable
* High-temperature version without PML
Maximum cable length
Conductive measurement of
conductivity
Max. 100 m (328 ft) with CYK71
Resistance measurement Max 15 m (49.2 ft) with CYK71
Inductive measurement of conductivity Max. 55 m ( 180 ft) with CLK5 (incl. sensor cable)
Structure and termination of the measuring cables
