Abstract:
A temperature sensing device for test cylinder, comprising a heat-transfer member covered by a top cover, said top cover being provided at lower edges of two longitudinal walls thereof with a plurality of lugs that are adapted to be bent to firmly bind said top cover to said heat-transfer member; said top cover and said heat-transfer member that are firmly bound together by said lugs being entirely set in a receiving space defined by a holding case to form a temperature sensing unit of said temperature sensing device; said holding case having a multi-conductor cable externally connected to an end thereof with multiple conductors thereof extended into said receiving space; said heat-transfer member being provided at an upper side at a position best for correctly and accurately sensing a temperature of a test cylinder with an upper recess for receiving a sensing element therein, and at a lower side at a position opposite to said upper recess with at least one channel for accommodating conductors of said multi-conductor cable therein, said conductors being upward extended through holes provided at an end of said at least one channel into said upper recess to connect to said sensing element; said sensing element being located in said upper recess by injecting a predetermined type of resin into said upper recess to enclose said sensing element and adhesively bond a bottom surface of said top cover to said upper recess; and said top cover and said heat-transfer member being provided with concave top surfaces and said holding case being provided with concave top edges at two ends thereof, said concave top surfaces and said concave top edges having the same curvature as that of an outer surface of said test cylinder positioned on said top cover to enable close and fit contact of said test cylinder with said concave top surface of said top cover.
