The SCOPE (oscilloscope)/Tape Recorder/Analyzer output connector provides the output signal for connecting to oscilloscope, tape recorder, or other vibration analyzer. A 2- pin threaded connector is required for connection to this receptacle. The full-scale output signal voltage is 301 mV, RMS, for Metric units.
Vibration is a result of an excitation force or forcing function and may be either random or periodic. Vibration analysis can often pinpoint a failing element of a rotating machine in time to avoid catastrophic failure and costly replacement of machinery as well as lengthy production interruptions.
Standard calibration procedure consists of applying a precise (calculated) signal to vibration meter input terminals (to simulate the sensor) and adjusting the potentiometer on the respective circuit board to obtain the expected reading on the display. Equipment required for calibration. Function Generator.
The HFD processing method displays a numerical, overall value for high frequency vibration generated by small flaws that occur within a high frequency bandpass (5 kHz to 60 kHz). The detecting sensor’s resonant frequency is used to amplify the low level signal generated by the impact of small flaws.
4 Φεβ 2021 · The ISO 10816-3 standard provides criteria for evaluating the vibration of machinery according to measurements taken on non-rotating parts, such as bearings, bearing pedestals, or housings.
