Description

The Bently Nevada TACH100 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.

Applications

Power Industry: Serves as a local speed indicator for steam turbines, feedwater pumps, or fans in power plants. When the main control room is far from the equipment, maintenance personnel can read RPM data directly at the unit in real time.

Oil & Gas: Monitors centrifugal compressors, reciprocating compressors, or large pump sets. Its rugged industrial design (operating temperature -40°C to +70°C) allows it to withstand the harsh environments of refineries or offshore platforms.

Heavy Industrial Manufacturing: Used in power systems of steel mills, large transmission equipment in paper mills, or fan monitoring in cement plants, ensuring production line load balance through precise speed feedback.

Equipment Maintenance and Commissioning: Because it has an integrated power supply (-24 Vdc) to power the sensors, field service engineers often use it as a portable or semi-permanent tool for start-up and commissioning of new units or as an auxiliary speed measurement tool for vibration analysis.
