The compact Smart Sensor CSS 014 electronically records temperature and humidity and converts the measured data into a standardized analogue 4-20 mA or a digital IO-Link signal. The converted value signals can be utilized or further processed by a control or monitoring unit, e.g. a PLC control. The Smart Sensor is suitable for installation inside and outside the enclosure, even in harsh environmental conditions as can be found in the wind power industry: in shielded outdoor areas and exposed to vibrations.

  • Analogue/digital interface
  • Small size
  • Easy clip and/or screw fixing
  • High accuracy
  • Quick connection (M12 plug-in connector)
  • Large temperature and humidity range
  • Various application areas (IEC 61010-1/DIN EN 61010-1)
