Length of connecting cable
In order to ensure measuring accuracy, comply with the following instructions when installing the remote
version:
• Secure the cable run or route the cable in an armored conduit. Movement of the cable can falsify the meas-
uring signal, particularly if the fluid conductivity is low.
• Route the cable well clear of electrical machines and switching elements.
• Ensure potential equalization between sensor and transmitter, if necessary.
• The permissible cable length L
max
depends on the fluid conductivity (see Figure).
