WORKING PRINCIPLE OF VIBRATION
It adopts imported core control unit and uses the principle of capacitive miniature pendulum. According to the gravity principle of the earth, the gravity of the earth can generate a gravity component on a corresponding pendulum when the obliquity motion is inclined, the corresponding capacitance can be changed, and the acceleration can be obtained by amplifying, filtering and converting the capacitance. The frequency is obtained by algorithm processing and data analysis according to the collected acceleration. Amplitude data information.
INSTALLATION DIRECTION
During installation, keep the mounting surface of the sensor parallel to the surface of the target to be measured, so as to reduce the influence of dynamic and acceleration on the sensor. This product can be installed horizontally or vertically. Please refer to the following schematic diagram for the installation method:
PRODUCTION INSTALLATION NOTES
Please install the tilt sensor according to the correct method. Incorrect installation will lead to measurement errors. Pay special attention to one "surface" and two "lines":
- The mounting surface of the sensor and the surface to be measured must be fixed tightly, smoothly and stably. If the mounting surface is uneven, it is easy to cause the error of the included angle measured by the sensor.
- The axis of the sensor must be parallel to the axis to be measured, and the two axes should not form an angle as far as possible.
