The new Endevco model 7286 and 7287 accelerometers with 2,000g range are designed for critical test applications requiring superior accuracy and low cost of ownership where the convenience of an adhesive mount package is preferred. Each unit comes with a certified performance level, avoiding the need to characterize the sensor before use and providing a low-cost, high-value solution for capturing critical data.
While targeted at vehicle "crush" zone applications where sensors are frequently difficult to retrieve after the impact event, these sensors can be used in any application where up to 2,000g shock needs to be measured and low cost and high dependability are desired. Ideal applications include on-vehicle locations such as bumpers, fenders, doors and trunk lids which are likely to be heavily damaged during test.
The model 7286 and 7287 offer important advantages such as the ability to predict error budgets. This benefit is the result of specification to "max" or "min" values of key parameters, not to "typical" as with other such devices on the market. 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. The model 7286 operates on just 2Vdc and provides a maximum output of 10mV full scale, making it possible to replace old strain-gage sensors. Additional features include full scale range of 2,000g; 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 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.
"These new models are designed and built based on our decades of experience in high-end transducers and crash testing," said Jennifer MacDonell, Senior Product Manager for Endevco. "This proven foundation provides the assurance that the sensor will perform when needed with the accuracy and reliability our customers expect."
