98 / APPENDIX A CONVERTING CONSTANTS
CALCULATING SPREADER CONSTANTS
The spreader constant can be calculated if the following is known:
A = Number of pulses per revolution of the sensor shaft.
B = Turns of the sensor shaft for each turn of the final shaft.
C = Pounds of material discharged per revolution of the final shaft.
EXAMPLE:
A = 360 pulses per revolution (for Dj sensor p/n 46436-017X).
B = 25 turns of the sensor shaft for each turn of the final shaft.
C = 50 pounds of material discharged per revolution of final shaft.
NOTES:
1. V-Box spreaders have a different SPR CON for each gate setting.
2. The number of pulses per revolution for several Dj shaft sensors are:
360 for p/n 46436-017X (standard Control Point

shaft sensor).
60 for p/n 10844-000X
900 for p/n 10837-00XX
