The Inertial's family of quartz inertial sensors use one piece, micromachined inertial sensing element to measure angular rotational velocity. These sensors produce a signal output proportional to the rate of rotation sensed.

The unique quartz inertial sensors are micromachined using photolithographic processes, and are at the forefront of MEMS (Micro Electro-Mechanical Systems) technology. The use of piezoelectric quartz material simplifies the sensing element, resulting in exceptional stability over temperature and time, and increased reliability and durability.
