General
The 501 Electrode Control is a simple and price competitive system
for level control in conductive liquids. The system includes a
transmitter for DIN-rail mounting and various level electrodes.

Special Features
• Price competitive and reliable system for level control in

conductive liquids

• The amplifier is easily mounted on a DIN-rail
• The electrodes can be suspended by a cable or threaded directly

to a Lexan and Noryl plastic electrode base housing with a 1”
thread (see diagram at far right)

• The electrode base housing can be mounted on a special acid-

proof MJK 316 SS sensor brackets (200219 and 200220) which
can be wall mounted, pipe or rail mounted (using Universal
Brackets 200205) or mounted on a wall with an extension arm
(200210 plus 200215)


Function
The transmitter generates an alternating voltage applied to the
electrodes. When the liquid connects the electrodes, the current
running between these is amplified and the output relay is activated.
Two electrodes can be connected to the unit for the detection of
one level, or three electrodes can be connected for the detection of
two levels; one for start and one for stop. In cases where the liquid
is in a conductive tank, or where for example a metal pipe is in
constant contact with the liquid, the tank or piping can be
substituted for one of the electrodes by simply attaching a wire to it
and the connection housing, usually as a common contact. (see
diagram top middle).

COMMON

Terminal 13 must always be connected to the high-level electrode.
This also applies if you change from pumping out (default) to
pumping in. Only here it will function as the STOP electrode.

Settings for pumping out / pumping in
The 501 Electrode Control is set up from the factory to pumping
out (emptying). This setting can be changed to pumping in (filling)
by moving a jumper inside the cabinet as shown below:
