Toshniwal Industries Long-Range Fiber Optic Temperature Sensor DTS1000

DTS1000 Long-Range Fiber Optic Temperature Sensor

DTS1000

DTS1000 is a long-range fiber optic temperature sensing system for continuous temperature monitoring across industrial assets. It uses Raman scattering and Optical Time Domain Reflectometry technology to measure temperature along the optical fiber route. Also, it supports 4 channels, up to 5 km single-channel measurement distance and up to 20 km total measurement distance. As a result, it helps users detect hotspots, locate abnormal heating and support early fire warning in cable galleries, power cables, tunnels and plant routes.

  • Up to 20 km total distance
  • 4-channel monitoring
  • 1 m standard alarm length
  • ±1°C measurement accuracy
  • Real-time hotspot location
