Live temperature monitoring for data center busways

A fiber-optic sensing cable follows the bus duct or busway and measures temperature continuously. The system locates hot spots by distance and connects alarms to named joints for faster, clearer investigation.

Application workflow

From route temperature to an actionable location

The sensing route is mapped to busway names and joint positions. Software then brings the live profile, route context, alarm status, and thermal history into one application view.

Continuous route visibility

View temperature by distance along each monitored busway instead of relying only on measurements at isolated points.

Named joint locations

Keep the channel, joint ID, route distance, measured value, alarm limit, and time connected in the same workflow.

Live and historical views

Use the current temperature profile for active events and the waterfall history to identify repeated or persistent heating.

Practical integration

Connect data and alarms through Ethernet, REST API, WebSocket, RS485 Modbus, or dedicated alarm relay outputs.

Live temperature profile

See hot spots in route context

Temperature peaks align with named joints and alarm zones. Each active alarm can show its severity, measured value, limit, route distance, location name, and time.

  • Separate channels keep monitored busways distinct.
  • Joint IDs connect physical locations with route distance.
  • Warning and critical thresholds support clear alarm handling.

Thermal history

Recognize persistent heating

A waterfall view adds time to the distance-based temperature profile. Repeated heating remains visible at the same route position, helping teams distinguish persistent conditions from a single scan.

DTS complements the data center's electrical protection and inspection procedures by adding continuous temperature visibility along the monitored route.

Representative configuration

5 km DTS for busway monitoring

These values summarize the PS-DTS-5KM-MM-E2000-01 configuration used in the application brief. Final equipment, sensing cable, alarm thresholds, and channel allocation should be matched to the actual busway layout.
