Mini high frequency low bandwidth accelerometer

Meggitt Sensing Systems Introduces Endevco® Miniature High-Frequency, Low Bandwidth Piezoelectric Accelerometer

Meggitt Sensing Systems has recently introduced the Endevco® model 7240C, a miniature piezoelectric accelerometer with low bandwidth flat to 30 kHz, expressly designed for general purpose high-frequency vibration measurements.

Featuring a lightweight sensor design which allows for high seismic resonance and ruggedness within the same package, the model 7240C offers low base strain sensitivity and excellent output stability over time, with a total package weight of just 4.8 grams, effectively eliminating mass loading concerns. The unit is hermetically sealed to prevent against environmental contamination and is a self-generating device which requires no external power source for operation.

Signal ground of the unit is connected to the outer case of the unit. When used with one of the supplied isolated mounting studs, the accelerometer is electrically isolated from ground. A specially designed low-noise coaxial cable is also supplied for error-free operation.  The sensor’s overall size, versatility and performance make it ideal for use within a variety of automotive, aerospace, commercial aviation, general laboratory testing and structural monitoring applications.

Recommended optional accessories for use with the Endevco® model 7240C include the model 133 three-channel signal conditioner; the new model 2771C–XX series in-line charge converter; and the model 3053VM1 HyperFlex cable assembly, all available from Meggitt Sensing Systems. In addition, all Endevco® sensors and instrumentation are accompanied by a comprehensive five-year product warranty.
