Endress+Hauser prolevel FMC 661 - Sensor Connection

2.4 Sensor connection
Sensor cable
Use commercial 2-core installation cable, max. line resistance 25 Ω/core, for the sensor/
transmitter cable — the Prolevel satisfies the quoted EMC standards with this cable.
Level probes and
sensors, channel 1
The Prolevel FMC 661 can be operated with a variety of sensor types, each requiring a
different electronic insert. For Channel 1, continuous level measurement:
• EC 37 Z or EC 47 Z for capacitance and Multicap probes
EB 17 or EB 27 P for Deltapilots S
Level limit switch,
channel 2:
The level limit switch may be a vibration probe — Liquiphant (liquids) or Soliphant (solids)
— or a capacitance probe, with electronic insert
• EC 16 Z/EC 17 Z for Multicap probes
EC 17 Z for other capacitance probes
• EL 17 Z for Liquiphant probes
EM 17 Z for Soliphant probes
EC 37 Z and EC 47 Z The electronic inserts EC 37 Z and EC 47 Z have two measuring ranges which can be
selected by inserting a bridge between terminals 4 and 5 of the insert, see Fig 2.6. Full
instructions on selection of the insert are to be found in Publication E 07.80.06/1c.
• Note the zero frequency f
o
____ and sensitivity S_____on the insert for the
range you have selected.
EC 17 Z The EC 17 Z electronic insert can be used at Channel 2 with capacitance and Multicap
probes for limit level switching. The connection diagram is shown in Fig. 2.6. Technical
information is given in Publication E 11.84.04/1a.
EC 16 Z The EC 16 Z electronic insert is for use on channel 2 with the Multicap probes with active
build-up compensation. Wire it up as described in the Technical Information Sheet
TI 170F delivered with the insert.
