EE441
EE441 strap-on sensors are used for temperature measure-
ment on round ducts and pipes.
Typical applications are heating systems (warm and cold
water pipes) and solar collectors. In addition to active out-
puts 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 IP65 housing and the mounting concept
allow for fast and easy installation.
The optional adapter EE-PCA and the free configuration
software EE-PCS facilitate the adjustment and setup of the
active temperature sensors.
