High temperature quartz accelerometer for oil drilling application

Quartz accelerometer is one of the main components of inclinometer. Accelerometer is used in rotating and vibrating environment. When accelerometer is in dynamic environment, the signal of gravity accelerometer will be affected, even beyond the measurement range of gravity accelerometer, resulting in large measurement error. Generally, the vibration acceleration near the drill bit is about 10 ^ 7g. So the accelerometer with larger range should be selected. HTS-JA6 quartz accelerometer high temperature quartz flexible accelerometer is a single axis torque feedback accelerometer. It detects the external acceleration signal by detecting the mass, and then demodulates and amplifies it by servo circuit. The output current signal is proportional to the acceleration signal. Product features: high temperature resistance, high temperature 185 ℃, impact resistance (1000g) MTBF, mean time between failure 1000-2000h, analog electrical signal output, wide voltage power supply, low power consumption, what problems have been solved, high impact resistance, inclinometer can not work normally under 1000g impact environment, which can not be solved for a long time ° The HTS-JA6 series can work at 185 ℃ for 2000h without failure. Behind its support is the technology of multi chip module thick film hybrid integrated circuit.
