Installation of the Moisture Sensor
On a Conventional Square Baler:
1. Locate a flat spot between 12” to 24” from the rear of the chamber, about
halfway up the side, on the
UNCUT SIDE
of the chamber.
NOTE: Readings from the cut side of the bale will result in greater
variations of readings and overall higher readings.
2. Tape the drilling template onto the
flat
location and drill all holes, using the
drill sizes indicated on the template. File any burrs from the holes.
NOTE: The beveled (leading) edge of the sensor plate must face the
plunger (opposite direction of bale movement).
NOTE: The sensor plate must mount flat and tight to the bale chamber
wall!
3. Mount the sensor assembly using hardware provided. Follow diagram in
Figure 2.
NOTE: Make sure that two (2) electrode contacts (carriage bolts) are not
touching any part of the metal bale chamber, by using the insulating
bushings and washers. Secure tightly with one big nut on each bolt.
NOTE: Make sure that the beveled (leading) edge of the sensor plate is
fastened flat and tight to the chamber wall. Secure tightly with two (2)
flat head bolts. (If the leading edge is not secured flat and tight to the
wall, hay passing under extreme pressure will pry up the sensor plate.)
4. Assemble a ring terminal on the sensor cable to each contact bolt. Place
ring terminal between two (2) metal washers and secure tightly with the last
two nuts (see Figure 3).
5. Route the sensor cable to the hitch area of the baler so that it does not
interfere with any moving parts. Secure the cable with nylon ties or tape.
NOTE: Use attached plug cover tethered to connector to keep out dirt
and moisture!
On a Large Square Baler:
1. Use the same instructions as above, except we recommend that you add a
1/4” thick piece of strap iron in front of the sensor plate’s beveled (leading)
edge. This will provide additional protection to the sensor plate.
On a Round Baler:
1. Locate a flat spot on the sidewall or tailgate, as low as possible to the bot-
tom, on either side of the baler. Use the same instructions as above.
NOTE: The beveled (leading) edge of the sensor plate must face the
pickup.
NOTE: Hay will begin to pass over the sensor as soon as approxi-
mately 1/4 of the bale is formed.
