• Working Principle and Applications of Accelerometer Sensor.

    Working Principle. The basic underlying working principle of an accelerometer is such as a dumped mass on a spring. When acceleration is experienced by this device, the mass gets displaced till the spring can easily move the mass, with the same rate equal to the acceleration it sensed.

    Inuse vibration is the vibration the operator experiences when the tool is running in a real work situation in a specific workplace. It depends not only on the vibration produced by the tool, but many other variables such as the condition and quality of the inserted tool, type of product, the state of maintenance of the power tool, the design of the process, the worker's posture and technique, etc.

  • Accelerometers: Principles of operation and applications

    PE accelerometers can be applied to measure vibration levels ranging from 4 g to >104 g. The useful measurement range of a given unit is often limited only by its signal conditioning and measurement systems. The accelerometers can be used to measure very low frequencies. In practice, the lowfrequency response is usually limited by the signal conditioning electronics in order to eliminate noise .

    Principle of Operation. When liquid covers the forks the frequency of oscillation drops and is detected by the switch electronics, which in turn changes the output state of the level switch to operate an alarm, pump or valve. The frequency of operation of the switch is chosen to avoid interference from normal plant vibration which may cause false switching.
