  • Analog/digital interface
  • Compact size
  • Clip and/or screw mounting
  • High accuracy
  • Quick connection (M12 plug-in connector)
  • Wide temperature and humidity range
  • Various application areas (IEC 61010-1/DIN EN 61010-1)

The compact Smart Sensor CSS 014 electronically records temperature and humidity and converts the measured data into a standardized analog 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, such as wind power.
