EN2000A9 Preamp Built-in Vibration Transducer Protection Instrument

    The EN2000A9 is a single-path vibration transducer and protection instrument based on microprocessor technology. It is suitable for on-site installation and guide rail installation even in hazardous environments. The eddy current sensor preamp has been integrated into the instrument so the measurement can be undertaken directly with an eddy current sensor probe connected by an extension cable the instrument .  

    The instrument can be used with various rotating machinery including turbine generators, gas turbines, hydraulic generators, compressors, fans, centrifugal machines.

 
Function Characteristics

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

  The eddy current sensor preamp has been integrated into the instrument to make site wiring and installation simple.

  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.

  RS-485 communication interface is provided and multi-machine communication is supported, facilitating the networked management of multiple meters.

  The EN2000A9 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.
