A optical current sensor is used to measure current, In CT there is a use of iron core but as the rating of current to be measured increseS the CT saturation occurs this will leads to inaccurate representation of The current, but this does not ocur in OCS ,It uses light to measure the current,Current flowing in a conductor induces a magnetic field, which, through the Faraday effect, rotates the plane of polarization of thelight traveling in a sensing path encircling the conductor.thus by measurin this rotation the current is measured.(by GAURAV GAUR LNT, India)
What else can I help you with?
Can an optical mouse that uses optical sensors be placed on nearly all types of flat surfaces?
Yes you can
Where can I find information on optical sensors online?
There is a pretty well-populated list of optical sensor manufacturers at http://www.sensorsportal.com/HTML/SENSORS/OptoSens_Manufacturers.htm for starters. Also, another rather large list of manufacturers and suppliers is located here: http://www.thomasnet.com/products/optical-sensors-73749350-1.html. As for information on them, wisegeek.com has a good article on them here: "http://www.wisegeek.com/what-is-an-optical-sensor.htm" Hope this helps!
What are optical sensors used for?
Optical sensors are used to detect and measure light levels, colors, distances, and patterns. They are commonly used in cameras, barcode scanners, medical devices, and industrial automation systems for tasks such as detection, sorting, and monitoring.
What are the main characteristics of microwave remote sensing and optical remote sensing?
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.
What is the difference between a laptop wireless optical mouse and a wireless laser optical mouse?
The laser wireless optical mouse has laser sensors to direct the mouse on the screen as without it is a roll ball used to do so.
What has the author Eric Udd written?

Where can I find good deals on used optical sensors?
You can find them at AMeds.com Look under health care.
What is the function of sensor on PLC system?
Sensors send incoming signals either digital or analog to PLC. There are a lot of types of sensors: inductive, capacitive, temperature, optical, etc.
What is the difference between photoelectric sensors and optical sensors?
A photoelectric sensor, or photo eye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively in industrial manufacturing. There are three different functional types: opposed (through beam), retro-reflective, and proximity-sensing (diffused).Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, for example: Lamps that turn on automatically in response to darkness. Position sensors that activate when an object interrupts a light beam.
Is fiber optics and Fiber optic sensors are same?
No, A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors").
What is a dead zone in sensors?
A dead zone in a sensor is the point where a sensor will not work. Ultrasonc sensors and specific optical sensors for example have measurement or detection ranges quoted as 30mm-300mm sensing. This means the sensor will not operate from 1-29mm or over 300mm.
Can you suggest a sentence using the word Optic?
We could see the deer through our optic sights.
