2.13 Conductivity Probe
The Conductivity probe senses the detergent concentration and measures the tank temperature if the optional temperature
compensated probe has been ordered. Correct probe placement is critical for accurate detergent concentration control.
Always use the new probe provided with the dispenser. When choosing a mounting location, make sure that the probe will be
completely immersed in wash tank solution, in an area that has a good flow of solution and close to the product entry point.
2.14 Inductive Probe (Optional)
Inductive probes are an option for scenarios where a contacting
conductivity probe will not be effective, such installations
with hard water or other contaminants. The inductive probe
also includes an integral temperature sensor for temperature
compensation/accuracy and to detect low temperatures in the
the tank.
Installing an inductive probe requires the same mounting hole size
in the wash tank as the standard conductivity probe. Similarly,
always confirm that the probe will be immersed in the wash tank
solution and will not interfere with the wash operation before
installing. The following steps describe the inductive probe
installation.
1) Cut a 22mm or 7/8” hole using a suitable hole punch or cutter
and ensure that all sharp edges, cutting debris and burrs are
removed.
2) Remove probe retaining nut from the assembly and ensure that
the rubber washer is against the back of the hex head of the
sensor at the base of the threads.
3) From inside the dish machine, route the end of the probe with
cabling through the hole with the rubber washer against the
inside wall of the tank.
4) Assemble the retaining nut back onto the probe from outside
the dish tank. It is critical that the hole in the inductive probe is
facing upwards, towards the water’s surface inside the tank.
Tighten the retaining nut by hand, and snug with a wrench to
prevent leaks.
Many dish machines will have knockouts provided for probe
installation and/or will have existing probes. Previously punched
holes may be suitable, but always confirm that the probe will be
immersed in the wash tank solution before installing. The following
steps describe probe installation.
1) Cut a 22mm or 7/8” hole using a suitable hole punch or cutter
and ensure that all sharp edges, cutting debris and burrs are
removed.
2) Remove probe retaining nut, plastic washer and one of the
rubber washers.
3) Insert the probe into the hole and re-assemble the rubber
washer, plastic washer and retaining nut back onto the probe
from inside the dish tank. Tighten the retaining nut by hand,
enough to prevent leaking.
