Product Overview

Celsius is a revolutionary high definition temperature measurement technology. Each Celsius system comprises a rack-mounted laser control unit and a set of sensing cables up to 5km in length. 

Legacy temperature monitoring systems make spot measurements using individual, independent sensors. Celsius is different. It uses a single sensing cable to measure thousands of points continuously along its length. The same cable can be used to monitor server halls, service areas, busbars, fuseboxes and other power transmission components. 

For monitoring applications where reliability, safety and seamless system integration are essential, the compact, low-power and user friendly Celsius system is the simplest and most comprehensive data centre temperature monitoring system available.

Product Features

Each Celsius laser control unit is packaged as a standalone rack-mountable unit containing sensing optoelectronics and an on-board processor. It supports multiple sensing cables using special adaptors.  Data is exported directly into Alquist’s DC View system for post-processing and analysis. 

Product Range

Celsius is available in Standard and High Resolution formats.

DTS 2000 measures the temperature every 2 metres along the entire fibre

DTS 4000 measure the temperature every 4 metres along the entire fibre

The sensing cable is identical with both systems, and the control unit can be upgraded from Standard to High Resolution without changing or modifying the cable. 

A range of multiplexor options are available if one DTS unit is required to support many shorter fibre-optic sensing cables. 

Resolution and Accuracy

Celsius sensor cables can be up to 5km in length, measuring temperature every metre at high definition.  One 5km cable will take 5000 independent temperature readings.  A typical 15 second sample time gives a measurement accuracy of 0.1°c, which is generally quite sufficient for data centre purposes. Longer sampling times allow accuracy up to 0.01°c  where required.

Temperature Range

With appropriate fibre containment and protection arrangements the Celsius system is capable of measuring temperature ranges between -195°c and +750°c.

Safety and Resilience

The Celsius system has been designed with data centre operating requirements in mind and has been tested to some of the industry’s most rigorous standards. The sensing technology has been refined over several years to withstand the harsh environments encountered on offsea oil rigs and and undersea power lines. The sensing cables themselves are passive, electrically inert, and contain no metal. Backup Celsius units can also be installed to provide extra resilience. 

Installation Procedures

The Celsius laser unit is designed to fit in a 19-inch rack, and requires a 240v power supply. The sensing cables can be run above server racks using existing conduits or a custom-designed suspension system. Cables can also be run underfloor to detect changes in plenum air temperature. As an added benefit, underfoor cables can also be used for leak detection where the leaking substance creates a small temperature differential.  

Maintenance and Durability

Celsius fibre-optic  sensing cables are virtually maintenance free with an expected service life of approximately 30 years. They can be repaired if severed or damaged.  It is recommended that each Celsius laser unit is serviced and calibrated annually.
