ABSTRACT:
This disclosure relates to a system for sensing the speeds of one or more movable members and selectively displaying one of the speeds. The system includes a speed sensor associated with each moving member and providing an output that is a function of the speed. A mode selector circuit directs one of the outputs to a multiplier circuit that converts the output to a form which is displayed or indicated in the desired system of units. The mode selector circuit sets up the system for one mode of operation upon initial energization but may be changed to a different mode by a sealed contactless switch. The multiplier circuit is programmable using an externally adjustable code device. The display automatically adjusts for different requirements in each of the modes and for different external operating conditions.
