micro-trak FLOWTRAK II, Reference Manual

The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse is
sent to the FlowTrak II console every time a magnet passes by
the tip of the speed sensor. For the speed sensor to operate
properly, the spacing between the magnets and the tip of
the sensor must always remain constant. Before permanently
mounting any parts, be sure that the location you have
selected will meet the requirements shown in Illustration 5.
NOTE: Observe magnet polarities (see previous section).

Attaching the Speed Sensor
Illustration 5
Connecting the Speed Sensor Cable
The speed sensor cable has a GREEN sensor body and mates
with the 3-pin connector which is marked with a YELLOW
cable tie. The speed sensor and the flow sensor are identical,
but must be connected to the proper harness connector. The
speed sensor always connects to the 3-pin M/P connector with
the YELLOW tie and flow sensor always connects to the 3-pin
M/P connector with the GREEN tie.
See FlowTrak II Wiring
Diagram on page 8.
The optional Run/hold sensor also uses the same type of
connector as the speed and flow sensors. However, the
Run/hold sensor has a GRAY tie near the 3-pin connector,
the sensor body is BLACK, and it always connects to the
main harness lead with the GRAY tie.

Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the FlowTrak II may be interfaced with a va ri ety of
other speed sensing equipment. Several options are listed
below.
Astro GPS Speed Sensor
The Astro is an easy-to-install economical alternate to radar
speed sensors. The Astro is available with either a 1 HZ or 5
HZ GPS receiver. The sensor converts GPS signals to a pulsed
speed signal, providing an accurate speed input even in
conditions where radar does not perform well.
Vansco
™ Radar Speed Sensor
The Vansco radar speed sensor uses a microwave (radar)
signal to deliver a reliable, accurate speed signal for electronic
equipment. It features state-of-the-art electronic design/
manufacturing, rugged aluminum housing and complete testing
and certification.
Radar Interface
The FlowTrak II may also be interfaced with most popular
radar ground speed sensors. An adapter cable is re quired for
proper interface.
SEE APPENDIX C FOR LIST OF ADAPTER CABLES FOR RADAR.
GPS Speed Sensor Interface
The FlowTrak II may also be used with most other GPS speed
sensors that output a pulsed signal, such as SkyTrak or
Dickey-John GPS speed sensors. An adapter cable may be
required.
