Ať už jde o sledování deformací tunelu při jeho opravách, sledování krátkodobého nebo dlouhodobého sklonu kolejového lůžka změn jeho výškových poměrů, sesuvy nebo nasycení půdy vodou, stav mostu, pohyb budov nebo opěrných zdí, zatížení, namáhání nebo náklon, systémy Senceive jsou určeny pro uživatelsky snadné, bezdrátové a naprosto bezporuchové nasazení.

The PT100 RTD Sensor Node allows for precision temperature monitoring using a variety of sensors. It uses the integrated radio transceiver to report its measurements through Senceive’s wireless communications network to a Gateway.

Temperature monitoring applications:

  • Steel structures
  • Rail, for critical rail temperature alerting
  • Concrete structures, including during curing
  • Heating, Ventilation, and Air Conditioning (HVAC) systems

Key benefits

  • Waterproof, robust connectors for simple installation
  • Accuracy of 0.1°C
  • Can have -IX triaxial tilt sensor integrated for combined tilt and temperature sensing in one unit
  • Integrated long life battery
  • 12-15 year battery life, including when acting as a relay node within the mesh communications network
  • Versatile mounting options
  • Waterproof to IP66 / IP67 / IP68
  • Firmware is remotely upgradeable over the air via the gateway reducing costly site visits
