OPTIONAL SUBMERSIBLE
TRANSDUCER
This unit may be equipped with an optional Elec­
tronic Pressure Switch (EPS) that works in con­
junction with a submersible transducer. The sub­
mersible transducer converts pressure to an elec­
trical signal proportional to liquid level. This electri­
cal signal is distributed to the digital display on the
EPS through a scaling circuit which converts the
electrical signal to “feet of water”.
When installing the submersible transducer, note
the following:
a. Handle the signal cable and transducer with
care during installation. Carefully lower the
transducer into the wet well or sump; do not
drop it to the bottom. To avoid clogging, sus­
pend the transducer off the bottom.
b. Be sure to provide sufficient room in the wet
well or sump so that the transducer does not
get drawn into the suction line. To prevent this,
a flexible suction hose may be extended to lay
along the bottom of the wet well or sump. The
transducer can then be attached to the hose
above the point where it bends along the bot­
tom. See Figure B-4 for a typical installation.
c. The wet well or sump must be vented to atmo­
sphere.
d. The EPS is scaled in feet of water column. If
the measured medium is other than 1.0 spe­
cific gravity, the reading on the EPS should be
divided by the specific gravity of the mea­
sured medium to obtain the actual level.
e. Thoroughly clean the transducer after each
use to prevent clogging.
Do not disassemble the transducer or
loosen the compression nut at the signal
cable entry. This will void warranty. There
are no user‐serviceable parts inside. Do
not nick or cut the jacket of the signal
cable; this will cause leakage and void
warranty.
