- Commodity name: HJAF3000HT Quartz Flexible Accelerometer
- Commodity ID: 1311258404592439296
- 型号: HJAF3000HT
- 产品概述: HJAF3000HT is a quartz flexible accelerometer. The applied acceleration causes the displacement of the quartz flexible mass block, and the servo circuit detects this displacement, sending it as an error signal to the PID loop. Finally, the transconductance amplifier drives the torque motor for correction, so that the current value reflecting the sensed applied acceleration achieves force balance.

HJAF3000HT is a quartz flexible accelerometer. The applied acceleration causes the displacement of the quartz flexible mass block, and the servo circuit detects this displacement, sending it as an error signal to the PID loop. Finally, through a transconductance amplifier, it drives the torque motor for correction, achieving a current value that reflects the perceived applied acceleration when force balance is reached. The choice of quartz material and the introduction of the PID loop give this type of accelerometer high precision, low drift over time, and low non-linearity characteristics. Therefore, quartz flexible accelerometers are currently recognized as high-precision measuring instruments. This accelerometer incorporates many microelectronic processing techniques and concepts in structural design, material selection, processing, and rigorous screening processes. It effectively controls material stress and processing stress, ensuring that the product meets or exceeds the quality consistency, shock vibration resistance, temperature drift, thermal hysteresis, long-term stability, and high-temperature characteristics of Japan's JA-25GA quartz flexible accelerometer. It can be widely used in oil LWD and MWD applications and can also be applied in military high-precision inertial navigation systems.
