Piezoresistive Accelerometer

Meggitt Sensing Systems has announced the global market launch of the Endevco model 727, an extremely lightweight piezoresistive accelerometer designed for accurate shock measurement during drop testing of consumer electronic devices, among other shock and impact testing environments. Available in four ranges (2,000g, 6,000g, 20,000g and 60,000g), the model can measure shocks in g ranges well above current drop test sensors. It offers high frequency response, from DC to 10kHz for the 2kg range and up to DC to 100kHz for the 60kg range, to capture the entire frequency range of interest. In addition, it has been tested and rated to survive shocks up to 1.5 times its range. At only 0.3 grams for the accelerometer body and 1.1 grams per foot for the integral 10-foot cable, mass loading to the test object is minimal. Its 0.28-inch diameter, anodized aluminum package is designed for adhesive mounting. The standard unit comes with an A2LA-certified calibration taken at 10 volts (other input voltages should be specified at time of order).
