Abstract
An RTD assembly includes a resistance temperature detector having two outputs, and a pair of electrical conductors including a first end and a second end. The electrical conductors are electrically connected at the second end thereof to the outputs of the resistance temperature detector. An electrically insulating polytetrafluoroethylene body, such as Teflon.RTM., includes a closed end, a cavity and an open end. The resistance temperature detector is disposed within the cavity of the electrically insulating body and proximate the closed end thereof. The electrical conductors extend from the cavity of the electrically insulating body with the first end of the electrical conductors being external to the electrically insulating body. A cured potting compound is disposed within the cavity of the electrically insulating body and about the resistance temperature detector and the second end of the electrical conductors.
