Yokogawa’s fibre optic heat detector

November 2018 Sensors & Transducers

Yokogawa has announced the DTSX1 fibre optic heat detector, an OpreXTM Field Instruments heat sensing and fire detection solution. Housed in an enclosure and suitable for use with specified fibre optic cables, the detector is a cost-effective all-in-one facility monitoring and fire detection solution. It is expected that this solution will aid in the timely identification of maintenance issues and thereby improve plant uptime and reduce maintenance costs.

Due to ageing facilities, labour related safety management issues, and various other problems, the risk of fire is always a concern at industrial facilities and there is thus a rising need for heat detection solutions. With their ability to measure the temperature distribution and pinpoint anomalies along the entire length of a cable, fibre optic heat detectors are a promising solution to such concerns, and devices of this type are increasingly used for monitoring temperature at a broad range of facilities.

In 2011 and 2014, respectively, Yokogawa released the DTSX200 and DTSX3000 fibre optic temperature sensors for use in applications such as the detection of abnormal heat build-up in coal and wood chip conveyors, the measurement of temperature changes in unconventional oil and gas wells, and the detection of the leakage of high and low-temperature liquids and gasses from pipelines and tanks. In response to the growing demand for facility maintenance solutions that can prevent incidents caused by heat-related failures at industrial facilities, as well as the need to comply with fire detection standards, Yokogawa has developed the DTSX1. This easy-to-deploy detector is specifically designed for use in heat sensing and fire detection.

Product features

Cost-effective solution

All components including an easy-to-read display, relay output circuits, alarm circuits, and other hardware required for heat detection are housed in a single enclosure. Suitable for use with Yokogawa-specified fibre optic cables and designed specifically for use in facility monitoring and fire detection applications.

Measure data from four cables up to 16 km in length

The system can accommodate up to four channels receiving temperature data via fibre optic cables that can each be up to 16 km in length. In terms of number of channels and total measurement distance: the number of channels can be set to 1, 2, or 4 and the measurement distance can be set to 2, 4, 6, 8, 10 or 16 km.

Ready-to-use GA10 templates for monitoring facility status

Templates have been created for Yokogawa’s GA10 PC-based data logging software that facilitate the display of DTSX1 data. Monitoring windows for each type of application enable the quick detection and location of failures.
