Product Description：
The 3300/50 Tachometer continuously measures shaft rotative speed, rotative
acceleration, or provides an output for zero speed indication. The tachometer
provides a proportional voltage or current output on the rear terminal strip and
supplies Alert status via relay contacts for use with an external annunciator
panel.
Although a single channel monitor, the 3300/50 Tachometer accepts inputs from
two transducers. Voting logic between the two transducers is internal to the
monitor, minimizing false indications in the event of a single transducer failure.
