    Voltage Type Triaxial Acceleration Sensor

    Introductions

    ER-AS-90 Voltage Type Triaxial Acceleration Sensor is a capacitive monocrystalline silicon sensor with an output interface of 0~5V, MK920. The finished product is composed of a microcomputer-processed silicon chip, a low-power ASIC for signal adjustment, a microprocessor for memorizing compensation values, and a temperature sensor.

    The product is small in size, low in power consumption, calibrated, fixed in structure, and stable in output. The new electronic configuration provides a solid-state reset power supply, comprehensive over-power protection, long-term stability and less than 0.1% of the typical value of the following scale factor deviation. This series of products have the characteristics of fixed structure, low power consumption, and good deviation stability, ensuring stable output reliability.
