EN2000A3 The EN2000 A3 and A3R is a speed monitoring and protection instrument. It is used to measure rotational speed and zero (reverse) speed of rotating machinery, to monitor rotational speed variation caused by faults and to protect the unit. EN2000A3 is applied to various rotating machinery, such as turbine generator, gas turbine, hydro generator, compressor, motor, fan, centrifugal machine, etc.; EN2000A3/R can be used by rotating machinery which might produce reverse rotational speed. RS-485 communication interface is also provided.
- The number of teeth (1-255) can be setup on the instrument and monitor the rotational speed of gear, keyslot with different teeth.
- The instrument has a “black-box” database to recall historical maximum value to provide reliable information for fault analysis.
- The alarm point and alarm delay time can be setup using software to minimize false alarms and failed alarms.
- RS-485 communication interface is provided and multi-machine communication is supported, facilitating the networked management of multiple meters.
- The parameter setup or function selection of the meter can be undertaken using the buttons on the front panel or by communication with the central server computer, and password is needed for administration authority.
