EN2000A6 Speed Transducer& Protection Instrument

    The EN2000A6 is a rotational speed monitoring and protection instrument based on microprocessor technology. It is suitable for on-site installation or guide rail installation even in hazardous environments. It measures both rotational speed and zero speed of a rotating machinery shaft, to monitor rotational speed variation caused by faults and to protect the unit from serious failure.

    EN2000A6 can be used on multiple types of rotating machinery, such as turbine generators, gas turbines, hydraulic generators, compressors, motors, fans, centrifugal blowers.
 
Function Characteristics

The instrument construction incorporates a cast aluminum case that has a high anti-magnetoelectric and anti-impact capability.

The instrument can be setup to accept signals from various numbers of teeth and will monitor the rotational speed from key or slot inputs through built inn software.

The instrumenthas a “blackbox” database to recall historical maximum values that provide reliable data for fault analysis.

The parameter measured is the peak-to-peak value of vibration or the displacement value. The output will be a passive output of 4-20mA.

The output can be transmitted to DCS or PLC to form a control system that provides protection for the unit or through an RS485 communication interface to form a monitoring network.

The EN2000A6 has two setup modes: With LCD and setup buttons: setup can be undertaken at the place of work; Without LCD, setup can be accomplished at with the use of an EN2000A7 Hand-held Setup Instrument.
