Temperature transducer assembly

摘要

A temperature sensing assembly for a heat exchanger flow tube comprises a housing having a thin heat transmitting wall section in heat conducting engagement with a flow tube, and a relatively thick, heat insulating structural support wall section; a thermally responsive signal producing assembly comprising an electrical signal producing element in heat transfer relationship with the heat transmitting wall section; an anchoring arrangement for positioning the signal producing element in heat exchange relationship with the heat transmitting wall section; a heat transfer element between the housing and heat exchanger flow tube tending to maintain the flow tube and heat insulating wall section temperatures the same; and an insulating jacket surrounding part of the heat transfer element.
