摘要： In an embodiment, the present invention provides a device for measuring the pressure p of a fluid flowing through a pipeline, including: at least one primary sensor arranged on an outer periphery of the pipeline for measuring a primary physical measured variable which is dependent on the pressure p, the absolute value of the pressure p being obtainable by offsetting said primary physical measured variable against at least one calibration datum, the at least one calibration datum relating to the geometry and/or to at least one material property of the pipeline; and a calibration datum determining unit and an evaluation unit for determining the pressure p from the primary physical measured variable in conjunction with the calibration datum. The calibration datum determining unit includes a measuring pipe which can be fluidically connected to the pipeline, which differs from the rest of the pipeline in material and/or in cross-sectional geometry.

摘要： An environmental condition may be measured with a sensor (10) including a wire (20) having an ultrasonic signal transmission characteristic that varies in response to the environmental condition by sensing ultrasonic energy propagated through the wire using multiple types of propagation, and separating an effect of temperature on the wire from an effect of strain on the wire using the sensed ultrasonic energy propagated through the wire using the multiple types of propagation. A positive feedback loop may be used to excite the wire such that strain in the wire is based upon a sensed resonant frequency, while a square wave with a controlled duty cycle may be used to excite the wire at multiple excitation frequencies. A phase matched cone (200, 210) may be used to couple ultrasonic energy between a waveguide wire (202, 212) and a transducer (204, 214).

摘要： A pressure sensing apparatus is provided for sensing gas pressure at a pressure tapping. The apparatus has a pressure sensor which provides a pressure measurement signal in response to the pressure of a gas admitted into the sensor at a gas inlet port thereof. The apparatus further has a gas conduit which extends from the inlet port. An end of the conduit distal from the inlet port is adapted to receive the gas at the pressure tapping. The apparatus further has a condenser on the gas conduit. The condenser contains condensation surfaces on which humidity in the gas flowing from the pressure tapping to the inlet port condenses out. In operation the temperature at the condenser is lower than at the pressure tapping.

摘要： An ultrasound-based measuring device includes a measurement body, at least one ultrasonic transmitter for coupling ultrasonic measurement signals into the measurement body, and at least one ultrasonic receiver for detecting the ultrasonic measurement signals reflected at an end face of the measurement body. The at least one ultrasonic transmitter emits both a longitudinal and a transverse measurement signal. The influence of a physical disturbance variable on the measurement section traversed by the measurement signals during a determination of a measurement pressure prevailing at the end face and/or of a measurement temperature prevailing at the end face can be taken into account on the basis of the propagation times and a difference between the propagation times of the longitudinal and transverse measurement signals reflected at the end face.

摘要： A device for testing the inflation state of an cold gas inflator for an airbag has a gas reservoir that is filled with gas at a high pressure, in particular an inert gas. Oscillations of frequencies varying within a particular frequency range are generated at an exterior surface the filled gas reservoir by an oscillation transmitter and the resonance frequency is measured using an oscillation sensor. A comparator compares the measured resonance frequency with a resonance frequency that was determined at the gas reservoir filled with the volume of gas. The oscillation transmitter and the oscillation sensor are integrated in a unit such that the generation and frequency measuring of the oscillations are carried out at locations on the exterior surface of the gas reservoir that are distanced from one another with respect to a longitudinal axis of the gas reservoir.

摘要： The present invention relates to system for measuring pressure and temperature based on change in the characteristic properties of a medium for ultrasound under the effect of pressure and temperature. The invention is based on two waveguides where geometry is adapted to the medium's characteristic properties for ultrasound such that only planar pressure waves are generated in the waveguides. The first of the waveguides is arranged for measuring temperature due to thermal expansion of the medium, where the medium is pressure-compensated by means of an internal compensator to prevent thermal pressure accumulation, and where measuring temperature is based on the medium's specific known characteristic data for ultrasound under the effect of temperature under constant pressure. The second waveguide is arranged for measuring pressure, based on waveguide and the medium's known characteristic properties for thermal expansion and pressure, and where the thermal effect is corrected analytically based on measurement of temperature in the first channel. The physical principle of the invention is based on the properties of a medium (oil) where the stability for high temperature and pressure is crucial for long-term properties. Long-term properties of ultrasound sensors are not physically linked to the medium's properties, such that change in characteristic properties of ultrasound sensors does not impair the accuracy of the medium unless the function of the ultrasound sensors ceases. The physical principle of the invention allows an arrangement where ultrasound sensors can be separated from measuring channels by a pressure barrier, such that the integrity of the pressure barrier is not broken.
摘要翻译：本发明涉及一种在压力和温度的作用下，根据超声波介质特性的变化来测量压力和温度的系统。本发明基于两个波导，其中几何适应于介质的超声特性，使得仅在波导中产生平面压力波。波导中的第一个布置用于通过介质的热膨胀来测量温度，其中介质通过内部补偿器进行压力补偿以防止热压积聚，并且其中测量温度基于介质的特定已知特征数据用于超声波在恒压下的温度影响。第二波导布置用于基于波导和介质已知的热膨胀和压力特性来测量压力，并且其中基于第一通道中的温度测量分析校正热效应。本发明的物理原理基于介质（油）的性质，其中高温和高压的稳定性对于长期性能是至关重要的。超声波传感器的长期性能与物理性质无关，因此超声波传感器的特性变化不影响介质的精度，除非超声波传感器的功能停止。本发明的物理原理允许超声波传感器可以通过压力屏障与测量通道分离的布置，使得压力屏障的完整性不会破裂。
