Smart Sensor
CSS 014 | DC 24 V

  • Analog 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 to 20 mA 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 use in a wide variety of applications and can be used even in harsh environmental conditions, such as wind power.
