Irvine, California, USA – Meggitt Sensing Systems, a Meggitt group division, has announced the global market launch of Endevco® model 727, an extremely lightweight piezoresistive accelerometer, designed for accurate shock measurement during the drop testing of consumer electronic devices. The anodized aluminum package is suitable for adhesive mounting and comes with an integral 10 foot cable.
Available in four different ranges, 2,000g, 6,000g, 20,000g and 60,000g, the Endevco® model 727 can measure shocks in g ranges well above current drop test sensors. The 0.28 inch diameter package is designed to be mounted with adhesive, and at only 0.3 grams for the accelerometer body and 1.1 grams per foot for the cable, mass loading to the test object is minimal. The 727 has exceptional frequency response, from DC to 10kHz for the 2kg range all the way to DC to 100kHz for the 60kg range, to capture the entire frequency range of interest. The 727 has been tested and is rated to survive shocks up to 1.5 times its range. The standard unit comes with an A2LA certified calibration taken at 10 volts, other input voltages should be specified at time of order. All sensing elements are manufactured in-house at Meggitt’s MEMS facility in Sunnyvale, California, USA.
With its exceptional bandwidth and shock survivability, the Endevco® model 727 is suited to many shock and impact testing environments. The model 42894 removal tool is included with each unit and the model 31849 mounting kit is optional. Recommended signal conditioning for use with model 727 include the model 126 three-channel DC bridge amplifier, the model 136 three-channel signal conditioner; and the model 436 DC differential voltage amplifier.
