HTS-A Quartz accelerometer

Quartz accelerometer HTS-A series is a high precision vibration accelerometer, features with high accuracy and excellent repeatability. This quartz accelerometers are widely used in the vector’s micro-gravity measurement system, inertial navigation system and static angle measurement system. Quartz accelerometers are built in a temperature sensor for zero bias and scale factor temperature compensation, it can effectively reduce the impact of temperature factors.

Product Detail

The HTS-A series navigation grade quartz accelerometers with high range and high accuracy, excellent reliability and long-term repeatability. Its output current is linearly related to the force or acceleration it receives.

Users can select appropriate sampling resistors through calculation, and achieve the highest precision output. And the temperature sensor can be built-in according to user demands, which used to compensate Bias and Scale factor and reduce the influence of ambient temperature.
