Different instrument versions with plastic housings for different protection ratings are available to suit the particular measurement task. The measuring insert is normally fitted with a Pt100 temperature sensor to EN 60751, Class B, in 2-wire circuit. Versions with Pt500, Pt1000 or Ni 1000 can also be supplied. An extension in 3- or 4-wire circuit, starting from the terminals, is possible. A transmitter can optionally be integrated.
