1/1 · Then axial voltage sensitivity and frequencies work range are approximately 1.5 times increased in comparison with an accelerometer with one bimorph element [32]. The accelerometer represented in Fig. 13.31 has better specifications.

An ICP ® accelerometer is a sensor that generates an electrical output proportional to applied acceleration. ICP ® accelerometers are designed to measure vibration and shock for a wide variety of applications. They are simple to use and accurate over a wide frequency range which makes them the recommended choice for many testing situations. ICP ® is a PCB ® registered trademark that stands

Piezoelectric ICP® accelerometers afford a very high signal output (+/- 5 volts full scale) and the ease of two-wire electrical connectivity. Their inherent ruggedness enables them to be severely over ranged without damage.

DJB's range of accelerometers are available in a variety of configurations, we produce both Charge Output and Voltage Output IEPE Accelerometers including the worlds smallest stainless steel accelerometers (A/28/E and A/128/V) and modal clip mounted triaxial accelerometers (AT/11, AT/13, A/136). Our range also includes unique and industry

When using a piezoelectric accelerometer, y ou must be aware that piezoelectric accelerometers are great within their relatively wide frequency range, but at the outer limits they can experience very high deviations. Figure 4: Typical frequency response of a piezoelectric accelerometer is shown with a 10,000 Hz mounted resonant frequency.

These vibrations appear at specific frequencies across a very wide spectrum. Reliable measurements of low frequency surge pulsations, running speed harmonics, 

Similar to the sensitivity specification, frequency response application for a piezoelectric accelerometer, thus the designation “mounted” is added.

Applications. Major applications of piezoelectric accelerometers include: Engine testing - Combustion and dynamic stressing. Ballistics - Combustion, explosion, and detonation. Industrial/factory - Machining systems, metal cutting, and machine health monitoring. Original equipment manufacturer - Transportation systems, rockets, machine tools

The lower frequency limit of Metra´s transducers with integrated electronics is 0.1 to 0.3 Hz for most shear and bender accelerometers and 3 Hz for com- pression sensors. The upper frequency limit mainly depends on the mechani- cal properties of the sensor. In case of longer cables, their capacitance should be considered.

In the broadband noise image, the data was generated with a ±25g accelerometer with 14-bit resolution (the resolution of the sensor goes as high as 16-bit for sample rates below 8.5 kHz). This also equates to a resolution of 0.003g (50/214); and you can see how these data points are always separated by at least 0.003g. 7. Filtering
