TeeJet 844 Sprayer Control - Manual (Page 9)

Components: Two magnets, Sensor with attached connector cable, and
mounting hardware.
If you are installing a radar ground speed sensor, follow the instructions supplied
with that unit.
Location
The speed sensor assembly should
be installed on a non-driven wheel to
avoid potential errors that are likely to
occur from a slipping drive wheel.
Refer to Figure 1.
Proximity Sensor (optional)
An optional proximity sensor is
available to use in cases where space
is limited or for drive shaft mounting.
The proximity sensor will work by
sensing any metal object. The
proximity sensor must be mounted so
that the sensor face is within 1/8 to 3/8
inch (3-10 mm) of the metal object
being read.
