Access to Accelerometers
a complex subject in a simple way
In this chapter we want to look at the main properties or typical characteristics of an accelerometer. Besides the definition, we want to examine and understand the influence of the construction on the properties of the vibration sensor.
There are also industrial standards treating the properties of a piezoelectric accelerometer. First to mention is the ISO 16063 standard about methods for the calibration of vibration transducers and the two older standards ISA-RP37.2-1982 (R1995) and ANSI/ASA S2.2-1959 (R2016) also describing the way of measuring certain characteristics.
To bring some order into the sea of properties, I have grouped them along three main axes, namely amplitude-related properties, frequency-related properties and finally temperature-related properties.
I have also tried to separate the “good” properties or design typical characteristics of a piezoelectric accelerometer from the “bad” ones, which I have named Disturbing Factors and are described in the last chapter.
