2.2.6 Length of connecting cable
Comply with the following instructions in order to ensure correct measuring results:
• Secure the cable run or route the cable in an armored conduit. Movement of the cable can
falsify the measuring signal, particularly if the fluid conductivity is low.
• Route the cable well clear of electrical machines and switching elements.
• Ensure potential equalization between the sensor and transmitter, if necessary.
• The permissible cable length L
max
depends on the fluid conductivity.
