Dualer IQ speeds up spine evaluations with dual inclinometry protocols recommended by the AMA and automatic data collection. For extremities, Dualer IQ helps you to quickly evaluate motion using dynamic dual inclinometry and static single inclinometry similar to using a goniometer protocols. Features of the Dualer IQ Digital Inclinometer: Records and stores results for up to 19 tests for faster ROM evals without stopping Dual inclinometry reduces repetitions and instrument placements for spine ROM Subtracts extraneous movement to display true spine ROM results Displays Primary and Secondary inclinometer values necessary for AMA impairment rating Meets AMA spine validity requirements with up to six repetitions per test Simulates simple goniometer techniques for efficient extremity evaluations Easily records ankylosis and antalgic restrictions From initial examinations to tracking progress, having tools that can take accurate measurements are an important part of rehabilitation. Measuring spine and extremity range of motion requires a device that is not only accurate, but time efficient and easy to use. The Jtech Dualer IQ Digital Inclinometer provides superior features and functionality compared to other non-computerized inclinometer systems.

History[ edit ] Drawing of an inclinometer, Museo Galileo, Florence. The glass face of the disc is surrounded by a graduated scale that marks the angle at which the surface of the liquid stands, with reference to the flat base. The zero line is parallel to the base, and when the liquid stands on that line, the flat side is horizontal; the 90 degree is perpendicular to the base, and when the liquid stands on that line, the flat side is perpendicular or plumb. Intervening angles are marked, and, with the aid of simple conversion tables , the instrument indicates the rate of fall per set distance of horizontal measurement, and set distance of the sloping line.
Louis"—in Charles Lindbergh chose the lightweight Rieker Inc P Degree Inclinometer  to give him climb and descent angle information. Uses[ edit ] Hand-held clinometers are used for a variety of surveying and measurement tasks. In land surveying and mapping, a clinometer can provide a rapid measurement of the slope of a geographic feature, or used for cave survey.
In prospecting for minerals, clinometers are used to measure the strike and dip of geologic formations. In forestry, tree height measurement can be done with a clinometer using standardized methods. Major artillery guns may have an associated clinometer used to facilitate aiming of shells over long distances.
Permanently-installed tiltmeters are emplaced at major earthworks such as dams to monitor the long-term stability of the structure. A clear line of sight between the user and the measured point is needed. A well defined object is required to obtain the maximum precision. The angle measurement precision and accuracy is limited to slightly better than one arcsec.
Accuracy[ edit ] Certain highly sensitive electronic inclinometer sensors can achieve an output resolution to 0. Typically in room ambient conditions the accuracy is limited to the sensor linearity specification.
Simple clinometer Clinometer designed to enable indirect fire capability with a Vickers machine gun circa Mechanical spirit level clinometer with micrometer adjustment Sensor technology[ edit ] Tilt sensors and inclinometers generate an artificial horizon and measure angular tilt with respect to this horizon.
They are used in cameras, aircraft flight controls, automobile security systems, and speciality switches and are also used for platform leveling, boom angle indication, and in other applications requiring measurement of tilt. Important specifications to consider for tilt sensors and inclinometers are the tilt angle range and the number of axes. The axes are usually, but not always, orthogonal. The tilt angle range is the range of desired linear output.
Common implementations of tilt sensors and inclinometers are accelerometer, Liquid Capacitive , electrolytic, gas bubble in liquid, and pendulum. Tilt sensor technology has also been implemented in video games. The PlayStation 3 and Wii game controllers also use tilt as a means to play video games. Inclinometers are also used in civil engineering , for example, to measure the inclination of land to be built upon. In this case, these inclinometers are compatible and partly interchangeable.
Two-axis digital inclinometer[ edit ] Two-axis digital inclinometer 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 MEMS inclinometers over conventional single-axis "bubble" or mechanical leveling instruments may include: Simultaneous measurement of two-dimensional X-Y plane tilt angles i.
Digital compensation and precise calibration for non-linearity, for example for operating temperature variation, resulting in higher accuracy over a wider measurement range. Inclinometer with gyroscope [ edit ] As inclinometers measure the angle of an object with respect to the force of gravity, external accelerations like rapid motions, vibrations or shocks will introduce errors in the tilt measurements. To overcome this problem, it is possible to use a gyroscope in addition to an accelerometer.
Any of the abovementioned accelerations have a huge impact on the accelerometer, but a limited effect on the measured rotation rates of the gyroscope. An algorithm can combine both signals to get the best value out of each sensor. This way it is possible to separate the actual tilt angle from the errors introduced by external accelerations.
