EE451
E+E sensors EE451 are used for temperature measurement
in heating, ventilation and air conditioning systems enabling
weather-dependent temperature regulation.
In addition to active outputs 0-10 V or 4-20 mA various types
of sensing elements such as Pt1000, NTC10k or Ni1000 are
available for passive temperature measurement.
The innovative enclosure concept (IP65) with a mounting
bracket allows for easy installation and unbiased detection
of ambient temperature.
The optional adapter EE-PCA and the free configuration
software EE-PCS facilitate the adjustment and setup of the
active temperature sensors.
