Distributed temperature sensing systems

2019-08-19 22:04

Rayleigh scattering based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device. Such a system allows acoustic frequency strain signals to be detected over large distances and in harsh environments.Distributed temperature sensing (DTS) systems are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is accomplished over great distances. distributed temperature sensing systems

The ULTIMA DTS range of distributed temperature sensing systems are the worlds highest performing family of Distributed Temperature Sensors. The ULTIMA DTS distributed temperature sensors offer the finest temperature and spatial resolutions, from 0. 01C and 35cm. It is a standalone unit with an onboard PC and userfriendly software interface.

This is the first power cable temperature monitoring system to be used in the Taipei MRT. The Linear Power Series solution continually monitors the temperature of highvoltage power cables. The DTS (Distributed Temperature Sensing) solution ensures a stable, safe and efficient power transmission and distribution. Distributed temperature sensing (DTS) measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element. Unlike traditional electrical temperature measurement (thermocouples& RTD), the length of the fiber optic cable is the temperature sensor. distributed temperature sensing systems Distributed sensing is a technology that enables continuous, realtime measurements along the entire length of a fibre optic cable. Unlike traditional sensors that rely on discrete sensors measuring at predetermined points, distributed sensing does not rely upon manufactured sensors but

Backed by more than 20 years experience and thousands of systems in the field, we deliver LIOS distributed optical temperature and strain sensing of unrivaled quality and performance. Get a passive, robust and reliable sensing system. distributed temperature sensing systems Launched in 1998, Sensornet provides the worlds most advanced asset monitoring solutions, using realtime distributed temperature sensing, digital strain, fiber optic leak detection systems and pressure measuring solutions. A Distributed Temperature Sensing system is ideal for temperature monitoring over long distances. A Distributed Temperature Sensing (DTS) system monitors temperature over long distances or across large surfaces, it could be along submarine or underground power cables. Distributed temperature sensing systems can typically locate the temperature to within a distance of 1m (this is known as spatial resolution) with accuracy to within 1C and with a AP Sensing provided its leading Distributed Temperature Sensing (DTS) system, the Linear Power Series, to monitor and secure the first 500kV power cables in Shanghai installed in a power cable tunnel over a distance of 20km.
