An x-ray image receptor, containing an anti-scatter grid and three AEC regions (represented by dark grey circles and square) These regions represent anatomical areas, e.g. lungs, spine. They can be selected individually, or all at once depending on the need. Automatic Exposure Control (AEC) is an X-ray exposure termination
Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind ...
(any device for measuring the work which will or would eventually be converted to heat and the ambient temperature) Entropy lowering its temperature—without losing energy—produces entropy (Example: Heat conduction in an isolated rod; "thermal friction"). calorimeter
A sailor checking the temperature of a ventilation system. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or another controlled atmosphere; or in applications where a fast response is required, the accurate surface temperature is desired or ...
The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...
A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
A calorimeter is a device which is used to measure and define the internal energy of a system. Some common thermodynamic meters are: Thermometer – a device which measures temperature as described above; Barometer – a device which measures pressure, most notably atmospheric pressure. [3] An ideal gas barometer may be constructed by ...
The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. [1] Infrared thermometers , can also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux.
