Abstract: A preassembled air data sensor probe and air data transducer assembly (10) has permanently connected flexible tubing (13, 14, 15, 16) coupling the air data transducer fittings and the sensor fittings (13A, 14A, 15A, 16A). The flexible tubing (13-16) permits the air data sensor (11) and air data transducer (20) to be installed into an air vehicle (18) after having been preassembled and pretested for leaks at the factory. The permanently connected assembly (10) avoids the need for calibration or pressure checks after installation on the aircraft (18). The preassembled flexible tubing (13-16) permits manipulation of the transducer (20) to mount it into its proper location even in tight quarters. The flexible tubing (13-16) can have a section that acts as a drain trap (41) for accumulating ingested water.

Abstract: A water separating device (10, 460D) for a pressure measurement such as static, pitot measurement system provides a passageway (82, 420A, 436A, 460A) having a portion formed as a plurality of ports (41, 420B, 436B, 460E) therethrough such that liquid water, and solid water such as snow and ice from atmospheric air are substantially removed from the air so that desired parameters such as temperature or pressure can be measured. Separation of water, snow and ice using ports (41, 420B, 436B, 460E) as disclosed eliminates additional chambers for collecting same and eliminates drain systems and drain valves.

Abstract: A transmitter (10) for use in a process control system has externally accessible actuators for permitting adjustment of the zero and span (or full scale) settings of the transmitter (10). The transmitter (10) has an explosion-proof housing (12) which includes an interior chamber (14, 16) in which transmitter circuitry is located. Each of the actuators includes a movable magnet (52A, 52B) which operates a magnetic reed switch (62A, 62B) located within the interior chamber (14) of the housing (12) through a wall (17) of the housing (12). By moving the magnet (52A, 52B) the corresponding reed switch (62A, 62B) can be changed from a non-actuated to an actuated state. When the zero reed switch (62A) is actuated, the transmitter circuitry adjusts its output so that the present value of the parameter represents a process zero. When the span reed switch (62B) is actuated, the transmitter circuitry adjusts its output so that the present value of the sensed parameter represents a process maximum.

Abstract: A transmitter (10) provides an output representative of a parameter. A generating circuit (11) in the transmitter (10) senses the parameter (12) and provides charge packets having adjustable magnitudes to a measurement circuit (60). The measurement circuit (60) measures the quantity of charge and provides a measurement signal representing the charge to a feedback circuit (50). The feedback circuit (50) is controlled by the measurement signal and provides timed feedback signals to the generating circuit (11). The feedback signals control the generation and magnitude of the charge packets such that the charge coupled to the measurement circuit (60) is finely balanced in a short measurement interval. The feedback circuit (50) counts the number of charge packets provided during a measurement interval such that the numbers counted are representative of the sensed parameter (12).

Abstract: A cell for sensing differential pressures has a single brittle material diaphragm (63, 93, 102) mounted on support plates (50, 75, 120, 130) positioned on opposite sides of the diaphragm (63, 93, 102). The diaphragm surfaces (43C, 77C, 102A, 102C) when at zero differential pressure facing the support plate (50, 75, 120, 130) are concave and shaped to conform very closely to the shape the diaphragm (63, 93, 102) has when it is deflected so that when the diaphragm (63, 93, 102) is under a selected pressure and it is forced against one of the support plates (50, 75, 120, 130) in either direction, the diaphragm (63, 93, 102) is substantially planar or flat and supported fully on its support plate (50, 75, 120, 130). The diaphragm (63, 93, 102) may be shaped by placing it under a pressure so that it bows or deflects and then grinding the surface (43C, 77C) opposite from the applied pressure flat. When the pressure is removed, the diaphragm (63, 93, 102) relaxes and the exact required shape is produced on the surface (43C, 77C, 102A) that had been bowed out and ground flat. The same procedure can be done to the other side (102C) of the diaphragm (102) or two diaphragm sections (43, 43; 77, 77) may be fixed together.

Abstract: A differential pressure sensor (10) senses a difference in pressure between a first input (low) pressure (12) or "reference pressure" and a second input (high) pressure (14) and provides a differential sensor signal representative of the difference in pressure. The reference pressure is sensed by a reference pressure sensor (26) which provides a reference signal representative of the reference pressure. The differential sensor signal and the reference signal are provided to a correction circuit. The correction circuit (24), which is preferably a digital computer, adjusts the reference signal and provides an improved output signal as a function of the differential sensor signal and the adjusted reference signal.

Abstract: A two wire circuit has a total direct current signal, It, proportional to a sensor signal which is responsive to a parameter to be sensed. It flows through a first terminal (22) which is coupled to an external power source (28) and load (30) and then through a second terminal. A current controller (20) is coupled to the sensor (14) and across the first (22) and second (24) terminals for controlling It. A feedback amplifier (48) amplifies a feedback signal which is responsive to It to provide an amplifier feedback signal. A span adjsutment (42) is coupled to the feedback amplifier (48) and the current controller (20) for receiving the amplified feedback signal to adjust the amplified feedback signal such that It is controlled by the current controller (20) as a function of the sensor signal and the adjusted, amplified feedback signal.
