A microwave level gauge has a flange adaptor which includes a first end for coupling to a process connecting flange and a second end for coupling to an electronics housing. The adaptor has a section of reduced cross-sectional area along its length between the first and second ends, which defines a thermal transfer restriction that restricts heat transfer from the first end to the second end. A waveguide extends through the adaptor, from the first end to the second end.

[ What is claimed is:] [1.] A microwave level gauge adapter for coupling between an electronics housing and a process connecting flange, the adapter comprising:a first, process connecting end for coupling to the process connecting flange and a second, electronics connecting end for coupling to the electronics housing;a length from the first end to the second end;a hub;a section of reduced cross-sectional area along the length of the adapter between the first and second ends, which defines a thermal transfer restriction that restricts heat transfer from the first end to the second end;a plurality of heat dissipating fins extending radially outward from the hub and having a surface area which increases from the thermal transfer restriction toward the second end; anda waveguide extending through the hub, from the first end to the second end.
