Temperature monitoring system for live parts of electrical equipment based on wireless SAW passive sensors (SAW-THERMO-V)

Appointment
  • temperature control of the live parts of electrical equipment and other parts of industrial installations;
  • generation of emergency warning signals and transmitting them to the automatic control system (ACS) for decision making;
  • providing the fire safety of electrical equipment (high-voltage transformers, switching devices, switchgear, low-voltage switchgear and other industrial installations).
Composition of the system:
  • «TERMO-В» sensors for electrical cabinets (up to 9 sensors);
  • Reader unit;
  • Reader antennas;
  • Sync cable
  • Cable assembly set;
  • Software.
