Distributed Temperature Sensing System (DTS) Controller WT-GL-100C
Distributed Temperature Sensing System (DTS) controller Model:WT-GL-100C
Description :
This kind of controller built-in optic fiber sensor module, industrial computer and touch screen. It uses DC24V power supply (or directly adopt fire power).
The functions are data display, temperature measurement, information storage and fire linkage.
The advantages are: small structure, easy to install, high stability, good compatibility, safety and reliability.
Applications:
●Cable tray, Cable tunnel, Cable trench, High-voltage cable.
●Highway tunnel, Subway tunnel, Dam.
●Rail tunnel, Utility tunnel.
●Convey belt, Coal conveyor, Coal storage yard.
●Oil tank, Gas tank, Oil convey pipeline, Gas pipeline.
●Warehouse etc.
Technology Principle:
DTS utilizes the Raman effect to measure temperature. An optical laser pulse sent through the fiber results in some scattered light reflecting back to the transmitting end, where the information is analyzed.
The intensity of the Raman scattering is a measure of the temperature along the fiber. The Raman anti-Stokes signal changes its amplitude significantly with changing temperature; the Raman Stokes signal is relatively stable.
The position of the temperature reading is determined by measuring the arrival timing of the returning light pulse similar to a radar echo. This method is called Optical Time Domain Reflectometry (OTDR).
Technology advantages:
● Fast speed position.
● It provides a continuous monitoring each 0.5 meter’s temperature change signals in the 20km length. You can set the alarm temperature at will.
● Accuracy: Sample interval is 0.5m, temperature resolution is 0.1℃, temperature accuracy is ±1℃, position accuracy is ±0.5m.
● Good compatibility.
● The system output way are RS232, RS485, built-in relay, RJ45 and other industrial agreement which connected with PC, fire alarm system and other control equipment to realize sound and light alarm, output signal exactly.
●Safety: Intrinsic safety, reliable, adopt optical signal.
