• Wide selection of probe assemblies
• All molded parts of rugged, impact resi st ant polyphenylene oxide
(PPO) and polystyrene (PS)

G e ne ra l
The Bulletin 13DJ3 S er ies 3000 Conduct i ve Liquid Level Control i s
designed to provide a reliable level detection of conductive liqu ids or
solids. No moving parts or flo ats are required. M etal probe rods are
placed in th e conductive liquid at the de sire d levels. The liquid or solid
conduc tive mate r ial completes the circuit between the probe rod or
rods to the metal mater ial container. If the container is non-conductive
(fiberglass, cement, etc.), an additio n al probe rod is used as a grounding
probe to complete th e elec tr ical circuit. Completion of the circuit will
cause the output relay to operate. The relay contacts may be used for
pump, valve, or motor control; audible and/or visual leve l in dication.
The controls will operate over a resistivity range of 0 to 60
Meg Ohms cm. This permits the sensing of liquid s or solids with very
low conductivity such as antibiotics, refr ig erants, or sand with a
moisture content as low as 5%.
In addition to high sen sitivity, the control has a fast response time and
can be wired for electronic control latching on certain applications,
allowing the use of both sets of relay contacts for ex ter n al lo ads.
A solid-state output sign al can be obtained from the control
sim ultane ously with a relay output. This sign al can be used for
electronic counting, data logging, or feeding infor mation to a
computer.
The control has protection against false operation due to lin e voltage
transients, line voltage dropouts of 1/2 second or less, or during initial
power up. These featu res allow the 13DJ3 Series 3000 Control to be used
in solv ing the more difficult in du strial level app lic ation s.
Resistan ce Sensing Control
PHOTOSWITCH Bulletin 13DJ3 is also designed to be used as a resistan ce
sensing control. In this application the control operates as an elec tronic
switch which converts the minute current flow through delicate
mech anisms or extremely light contacts into a switching output
capable of h andlin g relative ly heavy elec trical loads. The maximum
sen sitivity of the control when used for resistance sensing is 15
megoh ms.
