Precision Accelerometers for Motion, Vibration, and Seismic Measurement

Rieker Inc. manufactures precision accelerometers engineered to measure motion, vibration, tilt, and seismic activity with exceptional stability and accuracy.
Using capacitive spring–mass sensing technology and integrated signal conditioning, these accelerometers provide high linearity, low noise, and wide frequency response for dynamic and static acceleration measurement.
Rieker’s Accuracy Proven designs ensure reliable performance for vehicle dynamics, structural health monitoring, machinery diagnostics, and industrial control systems, where consistent, calibrated data is critical to safety and performance.
