Q: How to test the INC1000M inclinometer’s accuracy?

A: The accuracy of INC1000 inclinometer is tested on our high-precision turntable. The angle of the high-precision turntable is used as the reference angle. The angle measured by our inclination is compared with the angle of the high-precision turntable to calculate the error, then do the compensation to assure the ultra-high accuracy of INC1000M inclinometer.

Q: What is the difference between the static inclinometers and dynamic inclinometers?

A: The static inclinometers are equipped with a 2D MEMS accelerometer serving as a sensor cell. This type of inclinometer allows high precision to be achieved in a static system, or when the machine only performs slow movements. And the dynamic inclinometers (also called as vertical gyros) are equipped with a 3D MEMS accelerometer and a 3D MEMS gyroscope. An intelligent algorithm combines the signals from the accelerometer and the gyroscope to eliminate the effect of accelerations (e.g. due to rapid movement of equipment), vibrations and shocks. And INC1000M inclinometer belong to static inclinometer, which can provide high accuracy tilt angle in a static system or slow movement applications.

Q: How to calibrate the inclinometer?

A: The inclinometer needs to be calibrated on a high-precision turntable, and then the obtained data is used to perform algorithmic compensation on the inclination sensor. At the customer side, if there is no precision turntable, it cannot be calibrated, we can provide inclinometer calibration service.

Q: How to protect the INC1000M inclinometer components from failure?

A: The high-precision INC1000M inclinometer is mainly used for measurement in a static environment or similar static environment. It adopts IP67 protection, and the device will not fail in normal use.

Q: What are the applications of inclinometer?

A: Inclinometers are used for: –       Determining latitude using Polaris (in the Northern Hemisphere) or the two stars of the constellation Crux (in the Southern Hemisphere). –       Determining the angle of the Earth’s magnetic field with respect to the horizontal plane. –       Showing a deviation from the true vertical or horizontal. –       Surveying, to measure an angle of inclination or elevation. –       Alerting an equipment operator that it may tip over. –       Measuring angles of elevation, slope, or incline, e.g. of an embankment. –       Measuring slight differences in slopes, particularly for geophysics. Such inclinometers are, for instance, used for monitoring volcanoes, or for measuring the depth and rate of landslide movement. –       Measuring movements in walls or the ground in civil engineering projects. –       Determining the dip of beds or strata, or the slope of an embankment or cutting; a kind of plumb level. –       Some automotive safety systems. –       Indicating pitch and roll of vehicles, nautical craft, and aircraft. See turn coordinator and slip indicator. –       Monitoring the boom angle of cranes and material handlers. –       Measuring the “look angle” of a satellite antenna towards a satellite. –       Adjusting a solar panel to the optimal angle to maximize its output. –       Measuring the slope angle of a tape or chain during distance measurement.

Q: What is Two-axis digital inclinometer? 

A: Traditional spirit levels and pendulum-based electronic leveling instruments are usually constrained by only single-axis and narrow tilt measurement range. However, most precision leveling, angle measurement, alignment and surface flatness profiling tasks essentially involve a two-dimensional surface plane angle rather than two independent orthogonal single-axis objects. Two-axis inclinometers that are built with MEMS tilt sensors provides simultaneous two-dimensional angle readings of a surface plane tangent to earth datum. Typical advantages of using two-axis inclinometers over conventional single-axis “bubble” or mechanical leveling instruments may include: –      Two-axis MEMS technology enables simultaneous two-dimensional (X-Y plane) tilt angles (i.e. pitch & roll) measurement, eliminates tedious trial-and-error (i.e. going back-and-forth) experienced when using single-axis levels to adjust machine footings to attain a precise leveling position. –       Two-axis MEMS inclinometers can be digitally compensated and precisely calibrated for non-linearity for operating temperature variation resulting in higher angular accuracy over wider angular measurement range. –       Two-axis MEMS inclinometer with built-in accelerometer sensors may generate numerical data tabulated in the form of vibration profiles enable machine installer to track and assess alignment quality in real-time and verify structure positional stability by comparing machine’s leveling profiles before and after setting up.

Q: What is the Limitations of Static Inclinometers?

A: In case of strong shock and vibration, the physical damping in static inclinometers might not be sufficient to suppress disturbances. Software filters can only help to a limited extent in reducing the impact of such disturbances. For static inclinometers, “moving average” or “exponential” filters can be activated and configured to smoothen the signal, but with the downside that the fast reaction time of the MEMS inclinometer is lost and the response of sensor becomes slower. For dynamic movements with strong accelerations, SkyMEMS’s Dynamic inclinometers should be used. They are based on a different technology without physical damping so that there is no tradeoff between stability and response time.

Q: What is slope inclinometer?

A: A slope inclinometer (SI) is a device for monitoring subsurface movement. Slope inclinometers are often used to monitor the performance of slopes and embankments. They can provide early warning of developing instabilities; allow the assessment of pattern, depth and rate of movement; and help engineers make better and more timingly decisions on possible remedial actions to such sloping movements. Other applications include monitoring the impact of excavations on surrounding facilities, deformation of structures, and settlement of embankment fills and roadway subgrades.

Q: whether the connector and cable length can be selected?

A: yes, no problem, please let us know the connector type and cable length you want, then we can do it.

Q: How about the delivery time?

A: for our standard model, if we have them in stock, only need 2~3days to re-test before shipping, if it is out of stock, then need around 2 weeks to arrange the production and tests. For the ODM electronic product, if needing to modify the structure, it will need around 3~4 weeks to arrange the production and tests.
