    摘要: A pressure responsive apparatus having a Hall-effect detector is described. The apparatus preferably includes a pressure gauge having a Bourdon tube responsive to an external pressure. The Bourdon tube has mounted thereto a pair of magnets supported on, or attached to, an end thereof for generating a low power, magnetic flux field. The Hall-effect detector is mounted in proximity to the pair of magnets and generates an output voltage having values corresponding to movement of the magnets with respect to the detector. A processing circuit receives the output voltage from the Hall-effect detector, and in response thereto generates a plurality of output signals proportional to the sensed pressure variations in the Bourdon tube.

    摘要: A compensating bladder (30) for use in a pressure measuring device (10) for sensing pressure generated at a source. Pressure measuring device (10) includes a pressure responsive element (14) and pressure responsive structure (16) mounted within housing (12) for providing indications of pressures encountered at the source. The pressure responsive element (14) is connected by means of a socket (18), having an access opening (20), to the fluid source and for permitting pressure change to be sensed by the pressure responsive element (14). Compensating bladder (30) is disposed within the socket 18 to isolate pressure responsive element (14) from the fluid or gas entering the socket (18) and for forming a pressure transmitting chamber (66) that may be filled with a fluid. Compensating bladder (30) includes a generally longitudinal portion (44) and an integrally connected generally cylindrical portion (32). Compensating bladder (30) permits pressure changes at the source to be transferred to the chamber (66) and sensed without exposing the interior of element (14) to the fluid or gas undergoing measurement.

    摘要: A dry pressure gauge with a circular spring interconnecting the operational movement end of the Bourdon tube sensor and the driven mechanism that includes added mass to dampen frequencies above a desired design level. The added mass takes the form of added weight on the gauge needle in the form of a circle of material, weights on opposite sides of the needle from the pivot center, or a single mass weight on the needle below the pivot center. Circular spring to mechanism interconnect slotting is included, normally biased to an end limit by a bias spring in the driven mechanism, to allow below connecting spring force movement between the sensor and the driven motion translator to reduce friction.

The pressure regulator contains a flexible rubber diaphragm contacting a flexible diaphragm plate. The flexible diaphragm plate flexes upward or downward in response to changes in the control pressure and engages a pintle valve that controls the entry of gases to the pressure regulator. A system of chambers and passages controls the escape of gases by funneling escaped gases from a catch chamber to an exhaust port.

    摘要: A pressure responsive apparatus having an encoded disc provides preselected pressure indication. The apparatus preferably includes a pressure gauge having a Bourdon tube responsive to an external pressure. The Bourdon tube drives a conventional pointer indicator which has mounted thereto the encoded disc. Light is transmitted to the disc by means of fiber optic cables from a remotely positioned oscillator. Light if reflected by the disc at the preselected pressures and transmitted by fiber optic cables to processing circuitry that responds to reflected light signals as generated by the oscillator. To generate these light signals, light emitting diodes form a light source and the light signals are detected by means of phototransistors. For apparatus detecting two preselected pressures, there is a light source/light detector pair for each pressure. The processing circuitry responding to the outputs of the phototransistors generates visual indications of the preselected pressures.

    摘要: A valve (10) is interconnected in a flow line to control the downstream pressure by means of a relatively low pressure control device such as a block and bleed valve coupled to a control port (28). An activating piston (54) is moveable within a piston chamber (32) for activating a ball valve (44) to interconnect an outlet port (22) with an inlet port (20). In a manual reset mode, a pressurized fluid at a reset port (26) enters a regulator chamber (38). From the regulator chamber (38), the fluid flows through a passage between an annulus (42) and an extension tube (62) into the piston chamber (32) and acts against the activating piston (54). As fluid enters the piston chamber (32), the pressure acting against the activating piston (54) increases and moves the piston upward to activate the ball valve (44). A sealing surface (90) on a regulator piston (86) in the regulator chamber (38) prevents flow between the regulator chamber and the piston chamber (32) if the activating piston (54) moves upward to a position activating the ball valve (44), thereby limiting the pressure acting on the activating piston. A spring (64) urges the activating piston downward, deactivating ball valve (44) when the control port (28) is open for fluid flow. In the automatic mode, the inlet port (20) and the reset port (26) are interconnected so that a continuous predetermined pressure will exist in the regulator chamber (38) and the valve (10) will be automatically reset.

    摘要: A fluid pressure gauge type pressure responsive gauge drive having a drive to a sensor controller system with sensor controllers actuatingly engaged at respective adjusted pressure limits with gauge movement travel unimpeded by sensor controller contact in the range of movement between sensor controller pressure limit position settings. The drive may be connected to drive a fluid pressure gauge needle over an indicating dial and upper and lower pressure limit setting needles are adjustable to desired settings over the indicating dial. Calibration structures are provided for a coordinated setting of the gauge dial drive and in the drive of the sensor controller system calibrating each gauge structure for the "C" type bourdon tube installed. Fly open type activated block and bleed valves are used as sensor controllers mounted on cam adjusted pivotally-mounted upper pressure and lower pressure individual sensor controller mounting plates pivoted about a common pivot center that is the pivot center for the sensor controller activating arm. Further, a fluid pressure differential activated relay is shown useable in combination with the sensor controllers in a combined system.

    摘要: A pressure responsive apparatus having a flow-through element provides indications of measured pressure. The apparatus preferably includes a pressure gauge having a flow-through Bourdon tube responsive to an external pressure. The flow-through Bourdon tube drives a conventional pointer indicator and further supports a reflective target that is positioned in response to pressure applied to the Bourdon tube. Light is transmitted to the target by means of fiber optic cables from a remotely positioned oscillator. Light is reflected by the target and transmitted by fiber optic cables to processing circuitry that responds to reflected light signals as generated by the oscillator. To generate these light signals, light emitting diodes form a light source and the light signals are detected by means of phototransistors. A reference target is also provided along with a second light source/light detector pair. The processing circuitry responds to the outputs of the phototransistors and generates a controller output by use of a look-up table.

    摘要: In the measurement of fluid flow, the generation of a linearly varying signal and a pulsation free display are provided by a flow responsive indicator having digit displays for numerically indicating the rate of measured flow. The digit displays are driven in accordance with a measured flow signal applied to circuitry for generating an updated display signal from a previous display signal and the current value of the measured flow signal. This analog updated display signal is converted into a digital signal for driving circuitry connected to each of the digit displays. The measured flow signal applied to the indicator is generated at a flow transmitter including a transducer, such as a Hall effect element. This transducer generates a signal varying with flow in response to movement of a vane mounted in proximity thereto. To provide a signal varying linearly with flow rate, a flexible element extends into the fluid stream and by action thereof displaces the vane with reference to the transducer to generate the desired linearly varying signal.
