3.1.2. Connecting the signal cable

The signal cable connects sensor head and control module. Use only shielded cable. The maximum cable length depends on the cable specifications.

Cable:

Length l

Capacity CL [pF/m]

Inductivity LL [mH/m]

Approved parameters: UO, IO, CO, LO

Approved parameters: Ui, Ii, Ci, Li

Conditions: UO < Ui and IO < Ii and l x CL < CO - Ci and l x LL < LO - Li
