摘要： Differential pressure generator 100 includes a stacked pair of opposed novel gravity transducers of the inverted-cup falling-cylinder type. First enclosure 21 contains a first gravity transducer 23 and second enclosure 31 contains a second gravity transducer 33. First gravity transducer 23 includes first cylinder 24, and first piston 25. The first cylinder is mounted for gravity-driven, viscosity-limited motion with respect to the first piston to generate a first pressure difference. The second gravity transducer includes a second cylinder and a second piston. The second cylinder is mounted for gravity-driven, viscosity-limited motion with respect to the second piston to generate a second pressure difference. The first cylinder has a displacement volume that is equal to the displacement volume of the second cylinder, and the first cylinder is heavier than the second cylinder. The first pressure difference and the second pressure difference are summed in opposition to produce a reference differential pressure.

摘要： The present invention provides a system and method for calibrating pressure sensors associated with chambers in a processing facility. The system calibrates the pressure sensors while the chamber are open to each other, such as through an open slit valve or vacuum sealed door. Maintaining the pressure in the chambers relative to each other prevents a rush of gases, condensate or other foreign materials into an adjacent chamber that may occur when the pressure between the chambers is not equalized. This prevents contamination of the materials being processed, and eliminates the need for system shut-down to calibrate sensors. Also, since calibration occurs every time the slit valve is open, the calibration is real-time and does not allow the pressure differential between the chambers to become too great.
摘要翻译：本发明提供了一种用于校准与处理设备中的室相关联的压力传感器的系统和方法。当腔室彼此打开时，系统校准压力传感器，例如通过打开的狭缝阀或真空密封的门。保持腔室内的压力相对于彼此防止了当室之间的压力不相等时可能发生的气体，冷凝物或其它异物涌入相邻室中。这样可以防止被处理材料的污染，并且无需系统停机来校准传感器。此外，由于每当狭缝阀打开时进行校准，所以校准是实时的，并且不允许室之间的压差变得太大。

摘要： A vacuum generating device and method include a member that defines a passage, a first valve, a second valve, a fluid communication conduit, a transducer, and a processor. The passage extends between a first end and a second end, and includes a constriction that defines an orifice. The first valve connects the first end of the member and an ambient environment, and is electrically positionable in first and second configurations. The first configuration permits generally unrestricted fluid flow between the orifice and the ambient environment, and the second configuration substantially prevents fluid flow between the orifice and the ambient environment. The second valve has a first port and a second port. The first port is adapted for fluid communication with a pressure source at a first pressure level. The second valve is electronically adjustable. The fluid communication conduit connects the second end of the member and the second port of the second valve. The fluid communication conduit includes a fluid communication tap at a second pressure level. The transducer is in fluid communication with the fluid communication tap. The transducer senses the second pressure level and outputs a first electric signal. And the processor is in electrical communication with the second valve and with the transducer. The processor receives the first electric signal from the transducer and outputs a second electric signal to the second electric actuator. The second valve varies fluid flow through the orifice in response to the second electric signal.

摘要： The invention relates to a tester for pressure sensors in the wafer compound or isolated pressure sensors having a recess for the pressure sensors as well as means for electrical contacting of the electrical connections of at least one of the pressure sensors. The invention is intended to make it possible to test pressure sensors still in a wafer compound for their function. According to the invention, a pressure head is provided which has an interior space open on one side, the open face of which is capable of being mounted on the pressure sensor in such a way that the interior space is tightly sealed by the latter. In this way a static or dynamic pressure of specified amount and duration can be exerted on the sensor element at least so that the sensor element is moved out of its resting position. At the same time, the electrical connections of the selected pressure sensor are connected with an electrical evaluation unit.

摘要： A paint booth airflow control system is described for preventing paint particles and other contaminates from entering adjacent paint booth sections by equalizing air pressure differences between adjacent sections. Pressure sensors in communication with adjacent paint booth sections report pressure differences between the adjacent sections to an airflow controller. Responsive to the reported pressure differences the airflow controller adjusts paint booth airflow to equalize the pressure between adjacent sections. In order to maintain pressure measurement accuracy, automatic calibration modules periodically calibrate all pressure sensors to pneumatic references.

摘要： A variable force solenoid valve assembly generally includes a coil, magnetic pole, armature, and one or more variable size air gaps that are disposed within the solenoid. The solenoid may be calibrated by first energizing the solenoid coils and determining a corresponding desired hydraulic pressure, measuring the actual hydraulic pressure, and adjusting the magnetic flux until the desired output pressure is achieved.

摘要： A flow generator having use in the provision of CPAP or assisted ventilation treatment is disclosed The flow generator has a turbine for the supply of breathable gas which is driven by an electric motor and an associated motor power supply. The power supply in turn is controlled by a controller. A pressure sensing port measures delivery pressure that is passed to a pressure transducer, the output signal of which is passed to the motor controller. The zero offset of the pressure transducer is automatically calibrated on occurrence of the conditions where the turbine is not operating and no pressure activity is sensed by the transducer. The turbine not operating condition can be determined from Hall-effect sensors integral to the motor.

摘要： A scaled quadrature pulse output signal is generated for representing direction and volume in predetermined increments of the flow of a liquid or a gas through a meter. An unscaled pulse signal is received from a meter. A scaling factor is applied to each unscaled pulse signal for accurately representing an increment of volume. The increments are sequentially added or subtracted to/from one another (depending upon flow direction) and a scaled quadrature output signal is provided for indicating the direction of flow and the volume of flow in predetermined increments.
