Product Details

Distributed Temperature Sensor (DTS), a distributed fiber optic temperature measurement system, can detect the temperature distribution of a fiber optic cable that is several kilometers to tens of kilometers long. The spatial sampling interval is only 0.4m, and the detection cycle can reach seconds. The optical fiber itself is made of quartz and has excellent electromagnetic inertness. Therefore, DTS is an unprecedented "super temperature sensor" that is rapidly being applied in fields such as fire detection, power, petroleum and petrochemicals.

1. Working principle of fiber optic temperature measurement system

The mechanism of fiber optic temperature measurement is based on the backward Raman scattering effect. Laser pulses interact with fiber molecules, causing scattering. There are various types of scattering, among which Raman scattering is due to the thermal vibration of fiber molecules, which produces a light longer than the wavelength of the light source, called Stokes light, and a light shorter than the wavelength of the light source, called Anti Stokes light. The modulation of external temperature on optical fibers causes a change in the anti Stokes intensity in the fibers, which can be used to achieve distributed measurement of the temperature field along the fibers.
