A digital angle meter is an angle-measuring instrument used to measure angles.
A digital LCD display is used to display the measured values. Unlike analog inclinometers, it can also set any position as a reference and measure angles relative to the reference. This enables the high measurement accuracy and wide measurement range required for research and industrial applications.
For this reason, it is used in tasks such as plumbing, drainage, and steel-frame building construction. There are two main methods of measuring angles: one utilizing MEMS technology and the other utilizing electrolyte inclination.
Digital angle meters are used to measure the angle of incidence of drills at cutting sites. If the angle deviates from the target angle, the cutting direction changes, leading to wasted work and danger.
In addition, digital inclinometers are used to measure the angle of cranes at construction sites. Measuring the angle makes it possible to predict danger.
Other uses include solar tracking of solar panels to obtain sufficient charge. They are mounted directly on the measured object to make the most of the time it is facing the sun.
In addition, digital angle meters are also used in the medical industry to accurately determine the angle of the measuring rotator in CT and X-ray equipment. The positioning of the bed (table or couch) on which the patient lies leads to the accuracy of locating lesions on the human body.
Inclination sensors utilizing MEMS technology consist of an array of electrodes arranged in a fully enclosed chamber, one of the two poles being fixed and the other freely movable (connected to a spring spring).
When the sensor is tilted, the electrode at the free end changes its position relative to the electrode at the fixed end, and at the same time, the difference in capacitance is generated before and after the change. The difference in capacitance at that time is converted to an angle.
In the inclination sensor utilizing electrolytic solution technology, two pairs of electrodes are mounted on the bottom of the chamber parallel to the measurement axis and filled with electrolytic solution. When voltage is applied between the two electrodes, the current forms a dispersion field. As a result, the chamber tilts and the liquid level changes, so does the dispersion field.
Since the conductivity of the electrolyte is constant, the change in resistance depends on its relationship to the liquid level. In addition, since there are no moving parts other than the electrolyte, there is little wear and tear, and the electrolyte is highly shock resistant. Since the electrode used for measurement is immersed in the electrolyte, the electrode does not corrode.
