It operates as a stand-alone unit for direct speed indication or as a remote display for permanently installed monitoring systems. When the monitoring system is located in a control room or when no permanent system exists, the TACH100 provides reliable, real-time RPM readings at the machine.\u003c\/p\u003e\u003cp\u003eThis digital tachometer includes its own power supply, capable of powering a Proximitor sensor at -24 Vdc. It also accepts signal and common wires from an externally-powered Keyphasor Proximity Probe, allowing parallel connection with the monitor rack or directly to the probe. This flexibility makes the TACH100 an essential component for machinery protection and condition monitoring.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003cp\u003eThe TACH100 delivers precise speed measurement across a wide operating range. Its 6-digit LED display with 13.2 mm digit height ensures clear readability even from a distance. Measurement accuracy is within 0.015% of input speed, and display hysteresis requires only a 0.003% change in input signal to update the reading.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e1 to 999,999 rpm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1 rpm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e0.015% of input speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e6-digit LED, 7 segments, 13.2 mm height\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProximitor Power\u003c\/td\u003e\n\u003ctd\u003e-24 Vdc at 20 mA max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e110-230 Vac, 50-60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e1.01 W nominal (with 88888 displayed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInput and Output Flexibility\u003c\/h2\u003e\u003cp\u003eThe TACH100 accepts signals from any Bently Nevada Proximitor sensor with automatic threshold adjustment. Hysteresis is field-adjustable from 0.2 Vdc to 2.5 Vdc, and events per turn can be set from 1 to 99. This allows customization to match specific machine characteristics.\u003c\/p\u003e\u003cp\u003eFor output, the tachometer provides a clear digital display. The unit also includes a built-in fuse (1.5 Amp, SB) for electrical protection, ensuring safe operation under industrial conditions.\u003c\/p\u003e\u003ch2\u003eEnvironmental Durability\u003c\/h2\u003e\u003cp\u003eDesigned for harsh industrial environments, the TACH100 meets Pollution Degree 2 and Installation Category II standards.
