DESCRIPTION

The RTD-200 is a three-wire platinum RTD (resistance­temperature-detector) typically used with electronic control
systems that require accurate ambient temperature sensing.
The RTD-200 comes with a 1/2” NPT fitting that installs to the
appropriate conduit box. This allows mounting of the RTD in a
typical ambient location. This also allows for splicing of RTD
extension wire back to the controller.

INSTALLATION

The RTD-200 can be terminated directly at the controller using
the supplied 1/2 in NPT fitting. In this configuration, no additional
extension wire is required.

RTD wired directly to controller

(Distance from sensor bulb to controller
must be less than 4 ft)

Note: RTD should be placed in
a typical ambient location.
