Circuit diagram of a tilt sensor in the case of electronic components. There is a wide variety of technologies of this type of device. Here is a list of the main technologies : When the sensor is powered, a rolling ball drops to the bottom of the sensor to make an electrical connection with a conductive plate underneath.
The SR30 pyranometer is an example of an PV monitoring sensor, which can be used in two orientations (horizontal and in plane of array) for measuring irradiance. Photovoltaic system performance is a function of the climatic conditions, the equipment used and the system configuration. PV performance can be measured as the ratio of actual solar ...
A newer technology using microelectromechanical systems (MEMS) sensors enables tilt angle measuring tasks to be performed conveniently in both single and dual axis mode. Ultra-high precision 2-axis MEMS driven digital inclinometer/ tiltmeter instruments are available for speedy angle measurement applications and surface profiling requiring very ...
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 ...
The effective collection area of a flat-panel solar collector varies with the cosine of the misalignment of the panel with the Sun.. Sunlight has two components: the "direct beam" that carries about 90% of the solar energy [6] [7] and the "diffuse sunlight" that carries the remainder – the diffuse portion is the blue sky on a clear day, and is a larger proportion of the total on cloudy days.

Asset managers and bridge inspectors have mobile and web browser decision support tools based on analysis of sensor data. The Queensferry Crossing, currently under construction across the Firth of Forth, will have a monitoring system including more than 2,000 sensors upon its completion. Asset managers will have access to data for all sensors ...
A precession, or tilt, in the orientation of the rotor causes the London moment magnetic field to shift relative to the housing. The moving field passes through a superconducting pickup loop fixed to the housing, inducing a small electric current.
