        • Insufficient battery power or power module failure.

        Poor contact or short circuit of the power cord.

        Solution:

        Ensure that the power supply voltage complies with the technical specifications of the sensor.

        Replace the battery or check if the power module is working properly.

        Check if the power cord connection is secure and rule out short circuits or poor contact issues.

        7. Abnormal sensor output

        Reason:

        The sensor output data exceeds the expected range (such as showing a negative Angle or a sudden change in Angle).

        • Internal program or firmware failure of the sensor.

        Solution:

        Check whether the output data of the sensor complies with the technical specifications and recalibrate it if necessary.

        Update the firmware or program of the sensor to ensure its normal operation.

        8. Improper installation of the sensor

        Reason:

        The installation position is tilted or the fixation method is improper, resulting in inaccurate measurement angles.

        The sensor was damaged during the installation process.

        Solution:

        Ensure that the sensor is installed in the correct position and firmly fixed.

        When installing, avoid applying excessive mechanical stress to prevent damage to the sensor.

        9. Abnormal alarm function

        Reason:

        The alarm threshold was set incorrectly, causing the sensor to fail to trigger the alarm normally.

        • Fault of the alarm circuit or communication module.

        Solution:

        Check and reset the alarm threshold.

        Check the alarm circuit or communication module to ensure it is working properly.

        10. The service life of the sensor is shortened

        Reason:

        Long-term exposure to high temperature, high humidity or vibration environments leads to accelerated aging of sensor components.

        Frequent startup or shutdown of the sensor affects its lifespan.

        Solution:

        Select sensors suitable for long-term use and ensure their stability in the working environment.

        Optimize the usage frequency of sensors to avoid frequent starts and stops.

        11. The sensor is damaged

        Reason:

        The sensor was subjected to strong impact or vibration, resulting in damage to its internal components.

        The sensor operated under overload for a long time, causing the chip to burn out.

        Solution:

        Replace the damaged sensor.

        Optimize the usage environment of the sensor to avoid severe vibration or overloading operation.

        12. Software configuration issues

        Reason:

        The configuration parameters of the sensor (such as measurement range, sensitivity, etc.) were not set correctly.

        The data acquisition or processing software is incompatible with the sensor.

        Solution:

        Reconfigure the sensor parameters to ensure they match the actual requirements.

        Check whether the data acquisition or processing software is compatible with the sensor and update the software if necessary.

        13. Sensor output delay

        Reason:

        The response time of the sensor is too long to measure the Angle changes in real time.

        • Data transmission link delay (such as wireless communication delay).

        Solution:

        Choose sensors with shorter response times.

        Optimize the data transmission link and reduce latency.

        14. The sensor has insufficient anti-interference ability

        Reason:

        External electromagnetic interference or mechanical vibration affects the measurement accuracy of the sensor.

        Summary

        The common faults of inclinometers mainly focus on measurement accuracy, signal stability, environmental adaptability, communication functions, power supply capacity, as well as installation and configuration. For these faults, prevention and resolution can be achieved through methods such as regular calibration, optimizing the installation environment, inspecting communication and power supply systems, and updating firmware. At the same time, when choosing sensors, sensors with stable performance, high protection level and strong anti-interference ability should be selected based on the actual application scenarios to reduce the probability of faults.
