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 2.8.
Full instructions on selection of the insert are to be found in Publication TI 271F.
• Note the zero frequency f
o
____ and sensitivity S_____on the insert.
EC 17 Z The EC 17 Z electronic insert can be used at Channel 2 with capacitance probes for limit
level switching. The connection diagram is shown in Fig. 2.8. Technical information is
given in Publication TI 268F.
FEB 17 (P) The FEB 17/FEB 17 P electronic inserts can be used at Channel 1 with Deltapilot S probes
to measure level and volume in open vessels. The probe constants are listed in the table
on page 55.
EL 17 Z and EM 17 Z The EL 17 Z electronic inserts can be used at Channel 2 with Liquiphant for limit level
switching. For Soliphant the EM 17 Z insert is used. Publications BA 039F (013154-0008)
and BA 042F (014897-0002) contain full installation instructions.
EC 16 Z The EC 16 Z electronic insert is for use with the Multicap DC 16 probe with active build-up
compensation. Wire it up as the EC 17 Z (see TI 170F).
• The bridges 4 - 5 and 3 - 4 are not required.
