Vibration Monitors

All rotating machines or vibrating structures will exhibit resonances. i.e. Maximum amplitudes of velocity or displacement which occur at some characteristic vibration frequency. By using an accelerometer located at the point of the structure to be monitored and a suitable pick-up for the driving frequency, the basic data to derive velocity and displacement amplitudes can be obtained. It is possible to tune to harmonics of the driving frequency and monitor amplitudes thus providing a characteristic signature for the behaviour of the structure.

  • Inputs

    Screw lock connectors as standard or your own chosen connector type

  • Outputs

    BNC connectors as standard or your own chosen connector type

  • Transducers

    Handles a wide range of transducer types

  • Membrane front panels

    Simple push-button/LED controls. Optional RS232 serial control available

  • Enclosures

    2, 4, 8 or 16 modules, 2U height with mains or DC power options

  • Channels

    Specify as many or as few channels as you need without incurring the overheads of a sparsely populated multi-channel enclosure

  • Tracking Filter

    Tracking Filter FE-3051-TF

    The FE-3051-TF is a frequency controlled tracking bandpass filter with a standard range of 20 Hz to 1 kHz. (lower frequency ranges may be specified if required.) The tracking filter may be connected via the Tracking Ratio Adaptor (FE-3061-TA) to be centered at harmonics of the rotational speed. The filter gives an AC output at unity gain, and also a rectified and filtered DC output at 1 V DC for 1 V AC.

  • Tracking Ratio Adaptor

    Tracking Ratio Adaptor FE-3061-TRA

    The Tracking Ratio Adaptor satisfies the requirement to tune the system’s FE-3051-TF tracking filters to harmonics which may be fractions or multiples of a fundamental frequency. This unit accepts the fundamental frequency input from a tachometer transducer which may be a magnetic pick-up or other transducer type. It provides optical isolation and synthesizes an appropriate harmonic frequency from multiply/division factors set by banks of on board switches.

  • High Pass Filter

    High Pass Filter FE-301-HP6

    This module sets the lowest frequency of interest for the application. It is a fixed, user specified frequency with the value marked on the front panel. The pass band is unity gain and the frequency response is 6 pole Butterworth which provides very low in band ripple. A special dual frequency version is available.

  • Differential DC Amp

    Differential Charge Amp FE-1301-DCA

    This module may be set to an input range of 10, 20 or 50 pC/g. A precision integrator provides a velocity output in addition to the acceleration output. The acceleration output is scaled at 10 mV RMS / g (peak) and the velocity output is scaled at 2 mV RMS / mm/s (peak). A front panel control allows the module to substitute the system self test signal for the input signal providing through calibration.

  • Range Change / Integrator

    Range Change / Integrator FE-554-IRM

    The FE-554-IRM incorporates scaling and integrator functions to provide both velocity and displacement outputs in metric units (mm/s and micro m). Systems requiring scaling in imperial units (in/s and mils) may use the alternative FE-554-IRI module.

  • Self Test Module

    Self Test Module FE-5551-ST

    This module produces a precision sine wave simulating a velocity and displacement signal. This signal is routed directly to the input of the system’s charge amplifiers allowing complete system validation and calibration. The signal is also routed to the Tracking Ratio Adaptor(s) allowing stable self test outputs to be generated by the Tracking Filter(s).
