Quartz Flexible Accelerometers
Frictionless quartz flexure. Micro-g precision. Extreme environments.
Our quartz flexible accelerometers use a precision quartz flexure suspension for frictionless operation. Available with bias stability from 1μg to 15μg, including specialized high-temperature models rated to +180°C for downhole drilling. Applications include satellite microgravity, missile INS, oil & gas MWD, and seismic monitoring.
