　　The HJAF3000HT quartz flexible accelerometer (similar to the Japanese JA25GA) assembled instrument has achieved significant results in drilling in the Xinjiang block.

　　Zhengzhou Shiqi Measurement and Control Technology Co., Ltd. has achieved significant results in drilling in the Xinjiang block using our company's HJAF3000HT quartz flexible accelerometer (similar to the Japanese JA25GA) assembled instrument! Successfully completed the measurement and control tasks for two wells.

　　The depths of the two wells are 8500 meters and 8000 meters respectively (detailed data is shown in the table below).

　　This not only deepens the confidence of both units in further cooperation but also indicates that the four years of hard work by Hangjing people have been tested through practical application. We will continue to uphold the spirit of craftsmanship, persistently improve product quality consistency and reliability, and provide customers with more high-quality products and services that are more suitable for China's national conditions.

　　At the request of customers, Hangjing Microelectronics effectively controlled material stress, processing stress, and PN junction characteristic drift by fully absorbing and digesting the design concept and processing concept of JA25GA (JA-25GA has been embargoed against China), while introducing more microelectronic processing concepts and old refining selection concepts. This reduced copper loss in torque sensors, and dual isolation rings were used to cope with abnormal impact vibrations. The introduction of many concepts makes this type of accelerometer particularly suitable for use in harsh environments such as high temperatures, high impact vibrations, and ultra-long working hours.

　　HJAF3000HT/HJAF2000HT is a quartz flexible accelerometer. The externally applied acceleration causes displacement of the quartz flexible mass block. The servo circuit detects this displacement amount, sends it as an error amount to the PID loop, and finally drives the torque sensor for correction through a transconductance amplifier to achieve a current value reflecting the sensed external applied acceleration when force balance is reached. The choice of quartz material and the introduction of PID loops give this type of accelerometer characteristics such as high precision, low drift over time, and low non-linearity; therefore, quartz flexible accelerometers are currently recognized as high-precision measuring instruments.

　　It is recognized as a high-precision measuring instrument.

　　This type of instrument has complete independent intellectual property rights.

　　We named them HJAF2000HT (large meter) and HJAF3000HT (small meter). Below are physical objects and dimension diagrams:
