Product Summary

HZ-DTS is a distributed temperature sensing system designed for long-distance thermal monitoring of critical infrastructure. Unlike point temperature sensors, DTS uses optical fiber as a continuous sensing line, providing temperature information along the entire fiber route with accurate location data. It helps operators identify cable overheating, fire risks, pipeline thermal anomalies and data center power route temperature changes before they develop into failures.

13 km / 20 km

Up to 13 km for multimode DTS and up to 20 km for single-mode DTS configuration.

0.1°C

Temperature resolution for precise thermal trend monitoring.

±0.5°C

Temperature accuracy for reliable condition monitoring and alarm logic.

4 / 8 / 16 Channels

Flexible channel options for multi-route monitoring.

Raman DTS Principle

How fiber scattering becomes a temperature profile

Inside the sensing fiber, the laser pulse generates Raman backscattering. The Stokes signal is relatively stable and used as a reference, while the Anti-Stokes signal increases as temperature rises. HZ-DTS calculates temperature from the Anti-Stokes / Stokes ratio and uses OTDR return time to locate the event along the fiber.

Temperature changes the Anti-Stokes signal.

When the local fiber temperature rises, molecular vibration increases. This strengthens the Anti-Stokes Raman backscatter, while the Stokes signal remains comparatively stable. The ratio between the two signals is converted into temperature.

Temperature relation Temperature ∝ Anti-Stokes / Stokes intensity ratio. OTDR timing determines where that ratio change happens.

DTS records temperature data point-by-point along the sensing fiber.
Signal ratio Anti-Stokes rises with temperature. Stokes is used as the reference.
OTDR location The optical return time identifies distance, so each temperature value is mapped to a position along the fiber.
01

Laser Pulse

The DTS analyzer sends short optical pulses into the sensing fiber.

02

Raman Scattering

Stokes and Anti-Stokes Raman signals return from each point of the fiber.

03

Temperature Ratio

A stronger Anti-Stokes signal indicates higher local fiber temperature.

04

OTDR Mapping

Return time maps the temperature result to an accurate distance location.

Common questions about distributed acoustic sensing, fiber optic vibration monitoring, pipeline intrusion detection, perimeter security and conveyor belt acoustic monitoring.

What is HZ-iDAS used for?

HZ-iDAS is used for long-distance distributed acoustic and vibration monitoring. Typical applications include pipeline security, third-party intrusion detection, perimeter protection, conveyor belt roller monitoring, cable route disturbance monitoring and critical infrastructure protection.

What is the difference between DAS and DTS?

DAS detects acoustic and vibration events based on Rayleigh backscatter phase changes, while DTS measures temperature based on Raman scattering. DAS is used for intrusion, digging, vibration and acoustic event detection; DTS is used for temperature, hotspot and fire risk monitoring.

Which model should I choose?

Choose HZ-iDAS10 for short-distance high-bandwidth monitoring, HZ-iDAS20 for medium-distance pipeline or perimeter monitoring, and HZ-iDAS50 for long-distance infrastructure monitoring.

Can HZ-iDAS detect pipeline third-party interference?

Yes. HZ-iDAS can detect and classify mechanical digging, manual digging, vehicle passing and other external interference events along pipeline routes.

Can HZ-iDAS be used for conveyor belts?

Yes. DAS can monitor abnormal sound and vibration from conveyor belt rollers, bearings and mechanical components, helping locate fault points and support predictive maintenance.

Can the system restore sound at a selected point?

Yes. The software can monitor the time-domain sound signal at a selected fiber position and support sound restoration for event verification and analysis.
