Blower Speed Sensor
An inductive sensor on the blower fan provides speed information
to the ECU.
Bin Level Sensor
Optical bin sensors indicate when the level of product in the
bin has decreased to the level of the sensor. The same sensor
detects all types of products. The sensor height can be adjusted
vertically to set the alarm point at any desired level.
Meter Box Flow Sensor
A capacitive sensor detects when the meter box is empty. This
indicates if the bin is completely empty, or if the product has
stopped fl owing into the meter box because of bridging or a
leaky lid on the bin.
Meter Shaft Speed Sensor (Ground Drive)
A magnetic proximity sensor is used to detect the speed of the
meter shaft. This information is used to claculate how much
product has been applied and also indicate that the ground drive
system is function properly.
Meter Shaft Speed Sensor (Variable Rate)
If the air system was pruchased with the variable rate option, an
integral speed sensor is provided with the hydraulic motor. This
sensor is very accurate and provides the prcise meter speed
control that is needed.
Ground Speed Sensor
A Hall Effect sensor is used to measure ground speed by counting
the teeth on a sprocket located on the rear axle or the clutch
shaft.
