lightweight Rieker Inc P-1057 Degree Inclinometer to give him climb and descent angle information. Uses 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 including triangulation. 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. Factors which influence the use of inclinometers (Overall accuracy varies depending on the type of tilt sensor (or inclinometer) and technology used) Gravity Temperature (drift), zero offset, linearity, vibration, shock, cross-axis sensitivity, acceleration/deceleration. 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 Certain highly sensitive electronic inclinometer sensors can achieve an output resolution to 0.0001°; depending on the technology and angle range, it may be limited to 0.01°. An inclinometer sensor's true or absolute accuracy (which is the combined total error), however, is a combination of initial sets of sensor zero offset and sensitivity, sensor linearity, hysteresis, repeatability, and the temperature drifts of zero and sensitivity—electronic inclinometers accuracy can typically range from ±0.01–2° depending on the sensor and situation. Typically in room ambient conditions the accuracy is limited to the sensor linearity specification. Sensor technology 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. Yoshi's
