| 1. Product characteristics
The ACM-100 tri-axis accelerometer is a widely used acceleration sensor series products produced by Micro-Magic Inc 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.
The product has a small size, low power consumption, calibrated, fixed structure, and stable output. The new electronic configuration provides solid-state power for reset and comprehensive protection against overvoltage. The long-term stability and typical deviation of the proportional factor within the full range are less than 0.1%. This series of products has the characteristics of fixed structure, low power consumption, and excellent deviation stability, ensuring outstanding output reliability.
