摘要

ADJUSTABLE TEMPERATURE SENSOR An adjustable temperature sensor control apparatus consists of a tube sealed from the atmosphere and having a well section containing mercury and an elongate capillary section. A stem is disposed at the bottom of the well and in direct contact with the mercury. Mechanical means are provided to vertically move the stem in the well to displace mercury in the well into the capillary and vice versa. A first electrical connector is in contact with the mercury in the well and a second electrical connector is positioned at a predetermined length in the capillary.
