Pressure loss due to adapters
Length of connecting cable When mounting the remote version, please note the following to achieve correct measuring results:
• Fix the cable run or route it in an armored conduit. Cable movements can falsify the measuring signal
especially in the case of low fluid conductivities.
• Route the cable well clear of electrical machines and switching elements.
• If necessary, ensure potential equalization between sensor and transmitter.
• The permissible cable length L
max
depends on the fluid conductivity. A minimum conductivity of
20 S/cm is required for measuring demineralized water.
• When the empty pipe detection function is switched on (EPD), the maximum connecting cable
length is 10 m (33 ft).
