Measurement of the depression, elevation, and slope of an object with respect to gravitational force is required in many real life applications today. The instrument used to achieve this purpose is called a slope indicator. There are several other names by which this device goes including level gauge, declinometer, slope alert, roll indicator, and gradient meter. The various names may be used in different applications.
Declinometers take both the positive and negative slopes of the object being measured. That means that the measurements can be taken as seen by the observe looking downwards and upwards on the object. Three major units of measurements are used. These units are topo, degree, and percent. The modern-day version of the instrument evolved from a predecessor, which was called an astrolabe. Astrolabes were in use during the Renaissance period.
The accuracy level in modern-day declinometers is very high. Various factors determine accuracy in these devices. Some of the determining factors include technology incorporated and the angle range. Output resolutions of over 0.0001 can be reached by those that incorporate modern technology. On the other hand, typical accuracy falls between 0.01 and positive or negative 2 degrees. Besides technology, accuracy is also dependent on temperature, repeatability, sensor linearity, sensitivity, and hysteresis.
Modern devices incorporate different technologies. In most cases, the gadgets operate based on generation of an artificial horizon with respect to which measurement of angular tilt is done. Roll indicators that employ this technology are incorporated in flight controls of aircrafts, cameras, specialty switches, and automobile security systems. When one wants to buy tilt sensors, two key factors to keep in mind are tilt angle range and number of axes in the device.
Inclinometers have several applications in modern life. They are useful in the monitoring of subsurface deformations and movements. Here, they are used to detect zones of movement so as to determine if the movement is responding to remedial measures, is accelerating, or is moving at a constant rate. The instruments also find use in checking if deformations fall within limits. This can be helpful in making sure that adjacent structures are not affected by movements.
After impounding a place, it is necessary to verify if structures such as abutments of dams and dams on the land or in the neighborhood must be verified. Such verification may be achieved using an inclinometer. Similarly, the monitoring of settlement profiles of foundations, embankments and related structures may be done using horizontal inclinometers. As such, with all these applications and many more, it is clear that the construction industry depends on this instrument heavily.
Inclinometers are made of two main parts, that is, casings and the measurement system. Taking subsurface measurements is enabled by the casing component. The casing component has grooves that control how the sensor of the device is oriented. It also gives the system a uniform surface for taking measurements from.
Casings of inclinometers can be installed on various platforms. Some of the commonest installation places and methods include fitting inside boreholes, burying in trenches, embedding in fill, casting into concrete, and attaching to structures. Factors to keep in mind when buying a casing are groove shape, coupling style, and casing diameter.
