APPARATUS FOR ROTATABLY SUPPORTING TEMPERATURE PROBE.

摘要

Any inclination of the plug (1) during rotation is limited by the inner surface of a sleeve portion (30). The contact portions are made of metal, and one is formed by employing a soft, electrically conductive material impregnated with a vegetable oil. To prevent any increase in the contact resistance and any drop in the insulation resistance owing to contamination or condensation, a hole (36) is provided at the top of the support apparatus (11), to form a passage for the escape of vapour. To prevent the vapour which has passed through the hole striking against a casing (18) and condensing, a heat-transfer plate (38) is provided immediately above the apparatus. Alternatively, a conical condensation plate (39) may be provided to prevent water droplets falling on the apparatus.
