Abstract
A flat plate of thermally conductive material, such as aluminum, has mounting holes for connecting it on one side on a support and on the other side to an instrument which is to be thermally stabilized. The plate is internally traversed by a heating wire and is recessed near one of its edges to provide a platform on which temperature-sensing control elements such as a thermostat, a heat limiter and an alarm indicator can be positioned in close proximity to the wire. The platform is encased by a housing in which these elements and their connections are embedded in synthetic potting resin.
Claims6
A device for mounting an instrument under thermally stabilized conditions on a support, comprising:
- a perforated plate of good thermal conductivity with parallel surfaces respectively engageable by an instrument and by a support connectable with said plate by fastening means traversing the perforations thereof;
- heating means in said plate forming a loop between said surfaces;
- temperature-sensing means on one of said surfaces disposed close to said heating means for controlling the operation thereof, said one of said surfaces being recessed adjacent an edge thereof to form a supporting base for said temperature-sensing means in close proximity to said heating means;
- and
- a housing secured to said plate, said temperature-sensing means being enclosed in said housing, the other of said surfaces being recessed opposite said base to provide an air space between a part of said plate forming said base and a support contacting said other of said surfaces in the vicinity of said housing.
A device as defined in claim 1, 15 or 16 wherein said plate is substantially rectangular, said edge defining a minor side of the rectangle.
