Optical fiber are generally dedicated to the transmission of information in telecommunication networks.
In addition, optical fibers can be used for other applications as a sensor for detecting temperature variations. Thanks to patented  pattern recognition algorithms, it can detect potential fire outbreak, overheating or intrusion. This is exactly what the TPHASE, developped by Emphase, does.
The TPHASE is a specifically designed device whose purpose is to send a light wave at a certain wavelength and to decode the resulting interferometry pattern that reflects a temperature variation.
In addition, the TPhase can be connected directly to existing Building Management Systems (BMS) using a ModBus, ethernet, wireless protocol, as well as to be connected to a Cloud Based Architecture.
The TPHASE is currently installed at The Hotel in Brussels to anticipate overheating or abnormal variations in a 27-storey chimney.
The maximum response time is one second and the deviation can be located at an competitive cost.
The Hotel chose the TPHASE for its attractive cost, reliability and easy integration into their existing system.
The TPHASE has the advantage of being easily installed in different infrastructures such as cable trays, industrial halls, clean rooms, tunnels, data centers, etc. Indeed, only the optical fiber must be installed and, depending on the configuration, it allows to measure a point, a line, a surface or a volume.
Finally, the particularity of the TPHASE is that it can monitor several kilometers (upto 15 km / 9.3 miles ) at the same time even if the environment is ATEX.
