HTS-JA4 Quartz flexture accelerometer

Some well-known quartz flexible accelerometers (quartz pendulum accelerometers) with high operating temperature 180°C, specially designed for harsh environment, our quartz accelerometers HTS-JA4 and HTS-JA6 can completely instead of QAT160 and QAT185 quartz accelerometers. We use a dual torque structure in our accelerometer sensors, which is different from other companies' products, it can make the quartz accelerometers' bias and proportional coefficient more stable.

Product Detail

The HTS-JA4 series quartz accelerometers with high temperature and vibration-resistance, excellent reliability and long-term repeatability, which adopts a unique high-temperature and shock resistance design, packing process and special circuit. It can be used for both static and dynamic testing. It’s also a standard vibration sensor.

Its output current is proportional to the measured acceleration, providing static and dynamic acceleration measurements.

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.

It can replace QA650 quartz accelerometer, T185 quartz accelerometer, T160 quartz accelerometer and JAE series quartz accelerometer. We adopt a dual torque device structure, which is different from other companies.
