Crush Test Accelerometer with Certified Performance


Endevco Corporation has announced introduction of the Endevco model 7287 crush sensor with performance certified to specifications for critical test applications requiring superior accuracy, reliability and low cost of ownership. The device provides for reliable, predictable performance in terms of several key parameters and avoids the need to characterize the sensor before use.


The new Endevco model 7287 is the latest innovation in Endevco's highly
successful series of transducers for crash test and related applications,long known in the industry for reliable performance and product supply. It provides a low-cost, high-value solution for capturing critical data from vehicle "crush" zones, while exceeding the capabilities of competitive offerings.


The model 7287 is best suited for applications where certified performance to a known specification for ZMO and sensitivity is required. Ideal applications include on-vehicle locations such as bumpers, fenders, doors and trunk lids which are likely to be heavily damaged during test. Because data gathered from these areas is critical, it is imperative that sensors function reliably.


Specified to "max" or "min" values of key parameters, not to "typical" as with other such devices on the market, the model 7287 offers important advantages such as the ability to predict error budgets. A "POP" calibration data sheet is provided with sensitivity, ZMO and full scale range information.


The model 7287 features input voltage of 10Vdc and output sensitivity of 0.10 mV/g. Additional features include full scale range of 2,000 g; frequency response of 4,000 Hz with resonant frequency of 20,000 Hz; a small, lightweight configuration for easy glue mounting; rugged, PVC-jacketed cable that is less than 2mm in diameter for easy installation and cable routing with shielding to preserve signal integrity. Three form factors are available for maximum flexibility, two with cable and one without cable for customers who prefer to do their own wiring.


"The new model 7287 is designed and built based on our decades of experience in high-end transducers and crash testing," said David Bucka, Automotive Market Segment Manager for Endevco. "That proven foundation provides the assurance that the sensor will perform when needed, and that the product will be built and delivered as requested."
