The Endevco Model 7293A Microtron accelerometer family uses unique variable capacitance microsensors and incorporates special filtering and shielding for EMI and RFI exposure.
New range of industrial accelerometers
This range of industrial Isotron accelerometer types use an Endevco high performance shear design piezoelectric sensor, with integral low-noise hybrid electronics
The Endevco model 7287 suits applications that require certified performance to a known specification for ZMO, including on-vehicle locations such as bumpers, bumpers, doors and boot 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", the model 7287 offers 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 an input voltage of 10V DC and output sensitivity of 0.10mV/g.
Additional features include full-scale range of 2000g a frequency response of 4000Hz with a resonant frequency of 20,000 Hz, a small, lightweight configuration for easy glue mounting, and a 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 a cable and one without a 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".
