The HTS-JA5 series quartz accelerometer with high performance, excellent
reliability and long-term repeatability, which adopts a unique structural design,
packing process and special circuit. It can be used for both static and dynamic
testing. It’s also a standard vibration sensor and inclination sensor.
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) Widely used in measurement while drilling system (MWD)
- Test cycle can be chosen (1 month, 3 months, 6 months, 12 months) Inclination testing of bridges, dams, coals etc.
- High output range High speed railway control
- Compact size Stability of ships etc.
- Low lag Railway track system
- High stability
- High accuracy
- Analog output
