Indoor, outdoor and channel RTD
temperature probe

■ For temperatures from -50 ... +90 °C (200 °C)

■ For application in the air conditioning technology

■ Protection class IP20 to IP65

■ Connection: in 2-wire, 3-wire or 4-wire circuit

■ Available with 4 ... 20 mA or 0 ... 10 V transmitter

Indoor, outdoor and channel RTD temperature probes for air conditioning technology are mainly
used for temperature measurement in rooms, in air channels and outdoors.

Various device versions made of plastic with different protection classes are available for the
respective measuring task.

The measuring insert is normally fitted with a Pt 100 temperature probe as per DIN EN 60751,
Class B in 2-wire circuit, versions with Pt500, Pt1000 or Ni1000 can also be supplied. From the
connection terminals, wiring in 3-wire and 4-wire circuit is also possible.
A transmitter can be optionally integrated.
