An exhaust gas temperature (EGT) gauge is a meter used for measuring the exhaust gas temperature of an internal combustion engine in combination with a thermocouple-type pyrometer.
The traditional video camera with its limited field of view makes it difficult for use in some of the applications in the field of computational vision. Catadioptric sensors are proving to be an apt solution for this issue.
Image sensors are miniature devices or circuits arranged on silicon chips, which are used for image capturing and sensing applications.
The bhangmeter is a non-imaging radiometer that was invented in 1948 with the purpose of detecting nuclear detonations and measuring the yield of a nuclear weapon.
A biosensor is a biological detection system in which a biological component is combined with a transducer to perform measurement of a biochemical quantity. The development of biosensors started with the invention of enzyme electrodes by Leland C. Clark in 1962.
Metal detectors are portable electronic devices used for detecting the presence of any metal close by. They operate by sensing changes in magnetic waves caused by metal. The metal objects can be anything from old coins to gold nuggets.
A tachometer is a device for measuring the rotation speed of an object such as the engine shaft in a car. It basically indicates the revolutions per minute (RPM) performed by the object. It is also referred to as tach, revolution-counter, rev-counter, and RPM gauge.
A net radiometer is an actinometer used for measuring net radiation at the Earth’s surface. The net radiation normal to the earth's surface is the difference between the total upward radiation flux and the total downward radiation flux.
