The ACM-100 tri-axis accelerometer is a widely used acceleration sensor series product produced by Micro-Magic Inc Hi-Tech Company with Swiss patented technology, which can be used in various fields such as vibration testing and impact testing. The product adopts digital interface output, with RS232, RS485, TTL, Modbus protocol, and RS422 optional. Different address codes can be set, and multiple sensors can be connected in series for long-distance measurement and data analysis at multiple points. ACM-100 is a single crystal silicon capacitive sensor, consisting of a silicon chip that has undergone micro mechanical processing, a low-power ASIC for signal adjustment, a microprocessor for storing compensation values, and a temperature sensor.
