- Commodity name: HJAF2000 Quartz Flexible Accelerometer
- Commodity ID: 1311258334488842240
- 型号: HJAF2000
- 产品概述: HJAF2000 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 perceived applied acceleration reaches a state of force balance.

HJAF2000 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, a transconductance amplifier 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 characteristics such as high precision, low drift over time, and low non-linearity, making quartz flexible accelerometers widely recognized as high-precision measuring instruments. This accelerometer incorporates many microelectronic processing techniques and concepts in its structural design, material selection, processing, and rigorous screening stages. This effectively controls material stress and processing stress, ensuring that the product meets or exceeds other quartz flexible accelerometers in terms of quality consistency, shock vibration resistance, temperature drift, thermal hysteresis, long-term stability, and high-temperature resistance. It can be widely used in oil LWD (Logging While Drilling) and MWD (Measurement While Drilling), as well as in military high-precision inertial navigation systems.
