Once the VibeHound has been connected to a computer's USB port and its
LabVIEW driver has been properly loaded into the laptop, it only takes a
click to obtain digitized time waveform vibration data. The datalogger
contains a piezoelectric accelerometer, constant current power source,
amplifier, filter, digital signal processor, data memory and USB client
transceiver. Additionally, bandpass filtering is built into the datalogger
allowing users to obtain digitized vibration data within two common
enveloping bands; 50 Hz to 1 KHz and 500 Hz to 10 KHz.
Data collection parameters such as
Sampling Rate (125 Hz to 65 KHz) and Sample Count (20 to 50,000) can be
easily configured via the LabVIEW interface. Through this interface the
VibeHound responds to a simple list of USB protocol commands such as
Configure, Acquire, Sleep, Wakeup, Status and EEPROM. After the VibeHound has
acquired the digitized vibration time waveform this data can be easily
exported and processed using additional LabVIEW modules to obtain various
vibration parameters such as FFT’s etc.
