The GKC370 vibration sensor is based on the principle of single crystal silicon MEMS capacitive sensing, providing analog voltage output signals with an output range of 0.5 V to 4.5 V. Its built-in compensation circuit can effectively reduce the impact of temperature and process deviations on measurement accuracy, thereby achieving good linearity and long-term stability.
This product has the following technical features:
-Integrated electromagnetic compatibility (EMC) and radio frequency interference (RFI) shielding design;
-Low power operation mode;
-Support multi range configuration of ± 2g, ± 4g, ± 8g, ± 16g (optional);
-DC coupling output interface;
-Frequency response range: 0 Hz to 200 Hz;
-Built in self checking function, supporting real-time monitoring of operating status.
Based on the above performance indicators, GKC370 is suitable for industrial vibration measurement, equipment status monitoring, and general motion detection applications.
