Abstract
A vibration measuring apparatus (10) inlcudes an accelerometer (12) which is contained within a surface micromachined integrated chip, and signal processing means including a high pass filter (14), a low pass filter (16) and an integrator (18).
Claims17
A machine vibration measuring apparatus comprising an accelerometer and a signal processing means arranged to receive a signal from the accelerometer and to produce an output signal characterised in that the accelerometer is contained within a surface micro machined integrated chip, and wherein the signal processing means includes a low pass filter, the low pass filter acting to remove accelerometer resonance from the signal.
A machine vibration measuring apparatus as claimed in any one of the preceding claims, characterised in that the signal processing means further comprises an integrator.
A machine vibration measuring apparatus as claimed in any one of the above claims, characterised in that the vibration measuring apparatus her comprises a display device arranged to display the output signal.
A machine vibration measuring apparatus as claimed in any one of the preceding claims, characterised in that the vibration measuring apparatus further comprises a temperature measuring portion.
A machine vibration measuring apparatus as claimed in any one of the preceding claims, characterised in that the vibration measuring apparatus is selectively operative by way of a switch.
A machine vibration measuring apparatus as claimed in any one of the preceding claims, characterised in that the signal processing means is comprised of digital components.
