Piezoresistive shock accelerometers, manufactured by MEMS technology, have low power consumption while still providing +/- 200 mV full scale output. They afford a wider operating temperature range when compared to mechanically isolated ICP® accelerometers. Their frequency response ranges from DC (0 Hz) to 20 kHz. To lessen the severity of response when their resonant frequency is excited, they incorporate squeeze film damping, achieving values of 0.02 to 0.06 of critical.
The Endevco brand has long been the industry standard for reliable measurements in extreme high g environments. As a part of PCB's line of sensors, these sensors are now backed by our Total Customer Satisfaction guarantee. Endevco brand piezoresistive high g shock accelerometers are available in both damped and undamped models to provide high-reliability shock and vibration measurements in extreme environments. With available measurement ranges from 2,000 to 200,000 g, these accelerometers feature rugged piezoresistive MEMS sensing elements.
