摘要： A temperature measuring device includes a temperature-responsive element that mechanically moves a first inductive assembly component relative to a second inductive assembly component in response to temperature changes. The movement of the first inductive assembly component relative to the second inductive assembly component generates a change in a local eddy current pattern that corresponds to the sensed temperature.

摘要： A temperature sensing probe assembly for correcting fluid volume readout of a fluid meter in response to fluid temperature in relation to a standard measurement of temperature for the fluid. A temperature sensitive bimetallic probe is adapted to be immersed in the meter fluid and is enclosed in a tubular metal sheath for protecting the probe against potential injury when handled. Perforations in the sheath enable direct contact between the fluid and the probe.

摘要： An improved closure for a pressure gauge includes a stem or a sleeve which selectively provides a vent path when set by the end user. The closure device provides an automatic venting if in the normally closed condition by means of an overpressure valve arrangement in the sleeve. Therefore the two functions are incorporated in the single closure device.

摘要： A vent plug assembly for relieving overpressure from within an instrument casing and comprising a body adapted for secured placement within an aperture defined in the exterior wall of the casing and having a thru-bore and a blind recess symetrically spaced apart and of like configuration and internal cross-sectional dimension. A cooperating plug having a top plate and a pair of dependent stubs of like cross-sectional configuration and spacing as the thru-bore and recess of said body is interchangeably insertable within the thru-bore and recess of the body with one of the stubs defining a blind upward recess and the other of said stubs defining a thru-bore. The plug is interchangeably displaceable manually such that when the respective thru-bore of the body and plug are interfitted, continuous venting occurs while when the blind recess stub of the plug is inserted in the thru-bore of the body, venting occurs only at a predetermined value of pressure build-up from within the casing sufficient to expel the assembly from the installed aperture of the casing.

摘要： A gauge (10) is disclosed which incorporates an improved case assembly. In one embodiment, a case (14) is designed for use with either a bayonet ring (22) or a friction fit ring such as an elastomeric ring (50) or a push in window (156). In the first embodiment, cam followers (28) are positioned in pockets (46) formed on the case (14) to orient the followers and the followers are then secured to the case, as by welding. Cam surfaces (32) on the bayonet ring (22) cooperate with the followers to secure the ring on the case. When using a friction fit ring (50, 150) the case defines an interior surface (44) to receive the ring. In a second embodiment, curved strips (132) are secured to the exterior surface of the case (130). Cam followers (140) are used on the bayonet ring (138) to cooperate with the cam surfaces on the curved strips to secure the ring to the case. Alternately, an elastomeric ring (50) or push in ring (152) can be used with the case (130).

摘要： A liquid filled pressure gauge in which temperature induced volumetric changes inposed on the liquid fill are compensated for by a tensioned flexible diaphragm secured in a pressure-tight spaced relation on a cover plate for the gauge casing. For receiving the diaphragm pre-tensioned, the cover includes an annulus extending laterally from the cover surface with a negative draft on its circumference. By virtue of the diametral relationship between the outside diameter of the diaphragm about the draft surface of the annulus and the internal diameter of the case opening, the diaphragm incurs a friction fit as the cover is emplaced causing diaphragm tension to be increased.
