What is Digital Inclinometer used for?

The digital inclinometer is a measuring tool for measuring small angles, also known as inclinometers and surveying and mapping instruments. It can be used to measure the inclination of the horizontal position, the parallelism and perpendicularity of two parts, the straightness of machine tools and instrument guide rails, the flatness of worktables, and the flatness of flat plates, etc. With the continuous advancement of science and technology, the development prospect of the inclinometer is also very good, so the demand continues to increase, and it has a very broad application prospect in the market. Next, ATO will provide you with the application scope of the digital inclinometer in detail. Interested friends can take a look together.

Application field

The digital inclinometer is a digital display angle measuring instrument used to measure the inclination angle of a plane relative to the horizontal plane or the angle between two planes. It is mainly used for the measurement of inclined surfaces in civil engineering and the installation and measurement of industrial equipment. Its main function is to build trains, improve control automation, and detect the level of railway tracks. Also includes survey work for missiles, tanks, firepower, aircraft, ships, and more mechanical tables, lathes, and cutting tables that need to measure and control angles, levels, and positions in the fields of biology, medicine, robotics, etc. Generally speaking, it is mainly used for high-precision laser instrument levels, construction machinery equipment levels, remote range finders, high-altitude platform safety protection, directional satellite communication antenna elevation angle measurement, ship navigation attitude measurement, shield pipe jacking applications, large dam detection, inclinometer geological equipment tilt monitoring, fire pipeline initial shooting angle measurement, radar vehicle platform detection, satellite communication vehicle attitude detection, etc.

Principle of digital display angle measuring instrument.

Precision angle measurement is an important part of geometric measurement and a mature branch of metrology. The accuracy of angle measurements has also improved by more than a factor of 10 over the past 20 years. The angle measurement technology of the inclinometer is divided into static measurement and dynamic measurement. Some static measurement techniques are still the basis for dynamic measurements, and some dynamic angle measurement techniques can achieve static measurements.

Many important measurement and control instruments, such as gyro turntables, inertial navigation platforms, theodolites, stars, radars, missile launchers, space telescopes, high-precision CNC machine tools, robots, and other systems actually need angle sensors to measure the relative position of the measured object at different times. The absolute rotation angle of a reference direction or the relative rotation angle with respect to itself.

Digital inclinometer single-axis counts increase when an axis in the matrix is rotated in one direction and decrease when the direction of rotation changes. Counts are relative to the initial position of the inclinometer. When the inclinometer is initialized, its count value is set to 0. By calculating the angle of rotation, an inclinometer can easily measure position and velocity.

The calibration method of digital display angle measuring instrument

In order to improve the measurement accuracy of the digital display inclinometer, it is necessary to calibrate the inclinometer. After we reinstall the battery or press the value lock button for 6 seconds, the inclinometer will enter the calibration state, and the LCD will display the symbol "-1-". The inclinometer must be calibrated before it can be measured. The calibration steps are as follows:

1. Place the inclinometer facing the operator on the platform, short press the absolute measurement key, and the first stage symbol "-1" of the calibration displayed on the screen will flash.
2. After the symbol "-1-" of the first stage of calibration flashes for 6 seconds, the screen display will automatically switch to the symbol "-2-" of the second stage of calibration.
3. Rotate the inclinometer 180 degrees, and put the back of the product facing the operator in its original position.
4. Short press the absolute measurement key, and the symbol "-2-" of the second stage of calibration will flash.
5. After the symbol "-2-" of the second stage of calibration flashes for 6 seconds, the screen will display the angle value of the current plane relative to the horizontal plane, and the calibration operation is over.
6. The plane is to measure the zero-value error calibration of the working surface. Place the instrument on the level 0 flat plate, read its indication value, and then turn it 180° in its original position to read its indication value. When the two readings do not meet the requirements of Table 1, adjust the instrument according to the adjustment method in the manual until the readings of the above two operations meet the requirements, and the final display value of the instrument is zero error.

Note: The angle displayed after calibration is the angle between the current calibration plane and the absolute horizontal zero of the earth.
