摘要：There is described an improved sensor device for detecting the presence orabsence of fluid. The device comprises a housing member defining a chamber, a tipmember adapted for being exposed to a fluid and secured to the housing, a heat

conductive member within the chamber, a heater means within the chamber in conductiverelationship to both the tip member and the heat conductive member, and first andsecond heat responsive means. The improvement comprises providing the tip memberwith a first portion of a relatively thermally conductive material and a second portion of arelatively thermally insulative material.
