Intended for vehicle crash testing, the Model 7287 crush sensor provides certified reliable, predictable performance in terms of several key parameters and avoids the need to characterize the sensor before use. Applications include on-vehicle locations such as bumpers, fenders, doors, and trunk lids, which are likely to be heavily damaged during testing. Since data gathered from these crush zones is critical, sensor reliability is crucial.
The Model 7287 is specified to maximum or minimum values of key parameters, not to typical values, according to the company. A POP calibration data sheet is provided with sensitivity, ZMO, and full-scale range information.
The Model 7287 accelerometer requires an excitation voltage of 10 VDC and delivers output sensitivity of 0.10 mV/g. It also offers a full-scale range of ±2000 g with a frequency response of 0 to 4000 Hz and resonant frequency of 20,000 Hz. The device is small and lightweight for simple adhesive mounting and features a rugged PVC-jacketed cable that is less than 2 mm in diameter. Three form factors are available: two with the cable and one without the cable.
