DESCRIPTION
The nVent RAYCHEM RTD-200 is a three-wire platinum RTD
(resistance-temperature-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.
