The Bently Nevada TACH100-01 Digital_Tachometer can be used as a stand-alone unit for speed indication or in conjunction
with any permanently installed monitoring system as a remote speed indicator. It is often used when a permanent monitoring system is located some distance away (e.g. in a control room) or when no permanent monitoring system is installed and speed indication is required at the machine.
The digital tachometer is a compact unit, containing its own power supply that can power a Proximitor sensor (-24 Vdc).
The tachometer also accepts signal and common wires from an externally-powered Keyphasor Proximity Probe (such as may be available when a permanent monitoring system is installed). The wires can be connected in parallel with the Keyphasor input on the monitor rack or to the Keyphasor probe itself.
