Fiber optic temperature sensor wikipedia.
A multiuse fiber optic temperature sensor for measurement in a wide range of demanding applications where immunity to electromagnetic fields and explosion proof requirements are mandatory.
Temperatures are recorded along the optical sensor cable thus not at points but as a continuous profile.
Otg series fiber optics temperature sensors are designed for applications that require very focal temperature monitoring fast response time and or versatile sensor size packaging.
A fiber optic current sensor focs is a current sensor for measuring direct current.
The gallium arsenide scbg semiconductor bandgap technology otg series optical sensor is available in diverse packaging.
Sensors that vary the intensity of light are the simplest since only a simple source and detector are required.
Photon control is a leading manufacturer of fiber optic temperature and position sensors for the semiconductor and other high tech industries requiring accurate repeatable and reliable sensing in harsh environments.
The detector unit at the end of the sensor tube is equipped with gas sensors.
By using a single ended optical fiber around the current conductor that utilizes the magneto optic effect faraday effect focs measures uni or bidirectional dc currents of up to 600 ka within 0 1 of the measured value.
Sensors that vary the intensity of light are the simplest since only a simple source and detector are required.
In strong magnetic fields there is a small offset in the temperature reading approximately proportional to the strength of the magnetic field squared.
At least two fibre optic leak detection methods are being commercialized.
Fiber optic sensors offer complete immunity to rf and microwave radiation with high temperature operating capability so they can be used for measurement on patients and materials in magnetic resonance scanner mri.
From wikipedia the free encyclopedia distributed temperature sensing systems dts are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors.
Optical fibers can be used as sensors to measure strain temperature pressure and other quantities by modifying a fiber so that the property to measure modulates the intensity phase polarization wavelength or transit time of light in the fiber.
