Abstract
816,073. Pressure gauges. MECHANISM Ltd. Sept. 3, 1957 [Sept. 3, 1956], No. 26873/56. Class 106 (2). A pressure-gauge comprises a pressuresensitive capsule 1, a spring-loaded contactcarrying member 5 displaceable by the capsule 1, a micrometer 16 carrying a contact 13, and an electronic circuit, not shown, incorporating a cathode-ray tuning indicator of the type having a fluorescent anode, the making and breaking of the contacts 8, 13 sharply varying the pattern viewed. on the screen of the cathode-ray indicator. The micrometer 16 is graduated in millibars and is used to adjust the position of contact 13 relatively to the contact 8 carried by the spring-loaded lever 5. The apparatus is enclosed in a casing 20 provided with a window for viewing the screen and with a nipple 18 for connection to a pressure source. In operation, the micrometer 16 is adjusted as required until the pattern viewed on the screen is just on the point of changing, and the pressure read from the graduations on the micrometer. For calibration, the nipple 18 is connected to a source at a standard pressure, but in normal use it is left unconnected, thus equalizing the pressure inside the casing 20 with the ambient atmospheric pressure. Excessive expansion of the capsules 1 is prevented by a plate 22 secured to the casing 20.
