This series of products is based on traditional quartz flexible accelerometers, and highly integrates the current frequency conversion circuit with the servo circuit of the quartz accelerometer to realize a digital servo closed-loop circuit.
The product is frequency output, small in size, high in accuracy, and strong in anti-interference ability, and can be applied to high-precision rotary modulation systems.
High Precision & Stability: Delivers superior accuracy and long-term drift stability.
Frequency Output: Direct digital frequency signal for easy integration and noise immunity.
Compact Form Factor: Miniaturized design optimized for space-constrained applications.
Integrated Temperature Sensing: Built-in SMC18B20 sensor with dedicated output pins for real-time compensation
