Calculating The Initial Rate Sensor Cal. #
(Spreader Constant)
It is necessary to enter a Spreader Constant in TASC 6100
to ensure an accurate output from the conveyor. The
spreader constant represents the number of sensor pulses
per cubic foot of material discharged. The constant is
different for different gate settings on adjustable spread-
ers. Constants relating to particular gate settings should
be calibrated and recorded for the spreader.
Calculation of the initial spreader constant requires the
following information:
1) Gate height (H) and width (W) in inches
2) Number of sensor pulses for each revolution of the
spreader rate sensor (P)
3) The distance the conveyor moves during one
revolution of the spreader rate sensor (D), in inches.
Calculate the initial spreader constant as follows:
Where: Ft 3
r
is the volume discharged during each
revolution of the spreader rate sensor, in Cubic Feet.
