The Incline Compensator receives the static load cell excitation voltage from the electronic integrator and trans- mits a dynamic load cell excitation voltage, proportional to the secant of the angle of incline. V out = V in x secant ш where: V in = static load cell excitation voltage V out = dynamic load cell excitation voltage ш = angle of incline from horizontal Vout Vin ш Although the Incline Compensator was designed to work in conjunction with Milltronics integrators and scales, it can be used with equipment not of our manufacture, providing that the required excitation voltage meets our specification. For excitation voltages other than that specified, please consult Milltronics.

INSTALLATION The Incline Compensator is mounted in a painted steel NEMA 4 enclosure, suitable for the rugged outdoor envi- ronment in which variable incline conveyors are found. The unit must be mounted to the conveyor such that the card will be standing vertically and right side up when the conveyor is level. It should be rigidly mounted on the conveyor stringer and in line with the center of the belt scale. Furthermore the unit should be mounted such that it is not subjected to excessive vibration or shock from falling material.
