Piezoelectric accelerometers are high impedance charge mode sensors that are known for having a high MTBF. They are used with either a charge amplifier or in-line charge converter, like our 133 or 2771 products. These designs are ideal for use in extreme temperatures or in applications where the actual acceleration range is unknown. Endevco offers the largest selection of accelerometers in a variety of sizes and configurations to meet your testing needs. Special purpose units are available for flight, extreme temperatures and radiation environments.
Isotron® accelerometers feature an integral electronic impedance converter, eliminating the need for an external charge amplifier. They can drive long cables with minimal distortion and noise pick-up. The Isotron® electronics are compatible with the industry standard IEPE current sources that are built into many FFT analyzers and data acquisition systems. (Current sources and amplifiers are also available from Endevco). These accelerometers offer the ultimate in testing convenience and are available with a wide selection of ranges, sizes and shapes. Special accelerometers, pioneered by Endevco, include lightweight versions with a 30 kHz bandwidth, high sensitivity units for seismic measurements, and the lowest noise accelerometers for measuring whole body motion.
