HY-3S intelligentized speed meter is used for speed measuring and inverse rotating protection of power steam turbine, industrial turbine, pump and fan. It is non-contact measurement, can measure any teeth number, and accuracy is 1 rpm, can memorize and display maximum, 3rd level alarm switch, real time signal output and 4～20mA currency output.

1. Realized intelligentized process, all functions can be set by screen button.
2. Suitable for monitoring online in a long term, easy to install and commissioning.
3. Output value of alarm and trip for zero speed and inverse speed.
4. Output of 4～20mA.
5. Full scale, alarm, trip, overspeed value can be set by button.
6. Auto memorizes and review maximum value measured.
