Aerospace High-Precision Navigation Systems Accelerometer With Temperature Sensor
Product Introduction
ZT series quartz flexible acceleration sensor is a single-axis torque feedback accelerometer. It detects the external acceleration signal through the detection mass, and then demodulates and amplifies it through the servo circuit. Finally, the output current signal is proportional to the acceleration signal. Products are widely used in aerospace high-precision navigation systems.
