78462-02 Bently Nevada XDUCR I/O and Record Terminals

Features:

• Measures Shaft Rotative Speed and Acceleration

• Provides an Output for Zero Speed Indication

• Provides Proportional Voltage on Rear Terminal Strip

The Bently Nevada 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.
