The HTS-JA2 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.
Quartz accelerometers use an etched quartz bending inertial system with an amorphous quartz calibration mass structure to provide excellent deviation, scale factor and axis alignment stability. Quartz servo accelerometers are designed for aerospace and industrial applications. Integrated electronics generate an output current proportional to acceleration, providing static and dynamic acceleration measurement data.
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. HTS-JA series quartz accelerometers are high performance and high reliability, with a resolution of typically 5μg, it also can reach 1μg, and all our quartz accelerometers have built-in self-test functions.
