摘要
The thermometer includes a coiled bimetallic strip (2) which is able to rotate a shaft (3) in guide bearings. One of these bearings exerts a force in order to dampen oscillations of the mechanism. The shaft carries a drum with a scale (6) having graduations (12) arranged in a helicoidal pattern. The drum turns within a transparent tube (7) which includes a vertical reference marker (13). The tube serves as a magnifying lens. The thermometer includes a support loop (14 or 15). ADVANTAGE - Thermometer covers range minus 60 deg.C to plus 90 deg.C.
