Abstract
981, 793. Measuring pressure electrically. COAL INDUSTRY (PATENTS) Ltd. June 20, 1961 [June 20, 1960], No. 21549/60. Heading G1N. Apparatus for measuring the pressure inside a hydraulic roof support, e.g. a pit prop, comprises a pressure-sensitive resistor connected in abridge circuit with a similar element not subjected to the pressure, to provide automatic temperature compensation. The resistor may be made of a semiconductor or a carbon-loaded material, and may be encased in rubber.
