185℃ High Temperature Accelerometer for Down-Hole Drilling Sensor

Product Details

185℃ High Temperature accelerometer for Down-Hole Drilling Sensor

HQA-T185 Quartz flexible accelerometer

This product is a single-axis torque reaction type accelerometer to detect the external acceleration signal by detecting quality and then demodulated and amplified by the servo circuit, and finally output current signal proportional to the acceleration signal. It is widely used for inertial navigation of aeroscope and oil drilling or geological strapdown system.


● High temperature resistance

● Vibration and shock resistance

● Small volume and light quality

● Wide voltage supply, low power consumption

● Analogue signal output

● Flange or round embedded mounting
