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.
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.
Features Applications
- Internal temperature sensor for thermal compensation (optional) Attitude and Heading reference systems (AHRS)
- Test cycle can be chosen (1 month, 3 months, 6 months, 12 months) Inertial measurement units (IMU)
- High output range Inertial navigation systems (INS)
- Compact size Unmanned vehicle systems (UVS)
- Low lag Orientation drilling system for gas and oil industry
- High stability Railway track system
- High accuracy
- Analog output
