Line heat detector Honeywell DTS - evaluation unit, distance range 10 km


Approval: VdS, UL, ATEX, LPCB

DTS (Distributed Temperature Sensing) System is capable of detecting fires and accurately locate spots of the fire. The system allows to precisely measure, locate and signalize already small differences of temperature changes by measuring and highlighting temperature of a specific spot vs. environment. Fire resistant (PH category) sensing cable is capable to take signals also during a fire, even when temperatures are up to 750°C (max. two hours). That allows to monitor the progress of fire and supervise fire rescue action accordingly.
The system can work as a standalone system or be easily integrated into existing management platforms (e.g. SCADA systems) by either communicating directly over Ethernet (TCP/IP) using SCPI (standard commands for programmable instruments) or Modbus (IP or RTU).
