Measurement of angles of depression, slope, and elevation of an object or surface with respect to gravitational pull is usually necessary in certain applications. A slope indicator is the instrument used for taking such measurements. The device can also be referred to ass a slope alert, declinometer, level gauge, roll indicator, or gradient meter. Different names are applicable in different situations.
When measuring a slope of an object using a declinometers, both the positive and negative slopes are measured. That implies that measurements are taken as seen when an observer is looking both upwards and downwards. Units of measurements used are usually three in number and they include degrees, topo, and percentage. Astrolabe is the predecessor inclinometer from which the modern version evolved. Astrolabes were used during Renaissance.
Modern-day declinometers have a very high level of accuracy. Accuracy in these instruments is dependent on various factors. The main factors are angle range and technology incorporated in the device. Those with modern technology can reach output resolutions of 0.0001 degrees while typical accuracy is placed at 0.01 to 2 degrees in either positive or negative direction. Besides technology, other factors that determine accuracy are hysteresis, sensor linearity, sensitivity, temperature, and repeatability.
Different technologies are incorporated in modern devices. Most commonly, these devices work by generating an artificial horizon with respect to which angular tilt is measured. Devices that use this technology are most commonly incorporated in automobile security systems, specialty switches, aircraft flight controls, and cameras. When one is in search for tilt sensors, the two fundamental factors to consider are the number of axes and the tilt angle range.
Modern life finds many uses for inclinometers. These devices are valuable in the monitoring of subsurface movements and/or deformations. In this application, they are utilized in the detection of motion to establish if motion is accelerating, constant, or responding to countermeasures. Also, deformations that are within limits can be told through the use of the instrument. This assists in ensuring that subsurface motion does not affect adjacent structures.
After an area has been impounded, the stability of structures such as dam abutments, dams, and upstream slopes must be verified. This verification is done by inclinometers. Settlement profiles of structures such as embankments and foundations can also be monitored using horizontal inclinometers. Therefore, from the various applications of inclinometers, it is obvious that it is a vital instrument in construction and related industries.
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.
