LDT-100 Distributed Temperature Sensor

Product information "LDT-100 Distributed Temperature Sensor"

1 Channel; Dynamic Range >15 dB; Wavelength 780 nm; Spatial Resolution 10 cm; Measurement Range 250 m; Temperature Accuracy 1.5 °C; Optical Fiber Connectors E-2000 APC, Other

Luciol Instruments’ LDT-100 high-resolution distributed optical temperature sensor measures the temperature profile across standard optical fibers. The measurement technique is based on Raman scattering.

Due to the temperature dependence of the Raman scattering signal (Anti-Stokes), temperature variations along the sensing optical fiber are transformed in a variation of the backscattered signal.

The LDT-100 uses photon-counting technology to achieve a high detection efficiency and very high spatial resolution. An internal temperature calibration reference makes the system ready for testing and minimizes time consuming user re-calibration.

The LDT-100 also integrates OTDR testing capability which allows integrity and condition testing of the sensing optical fiber. The LDT-100 is a fully portable, simple and easy-to-use instrument, with user-friendly GUI software. A desktop version with USB interface is available as an option.
