Endress+Hauser Proline Promag 53H - Connecting cable length

Proline Promag 50H, 53H
Endress+Hauser 17
Length of connecting cable When mounting the remote version, please note the following to achieve correct measuring results:
• Fix cable run or lay in 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 permitted cable length L
max
is determined by the fluid conductivity. A minimum conductivity of
20 μS/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).
