摘要： A system for measuring the position of a rod element (3) as, for example, a hydraulically or pneumatically operated piston rod. Unlike the prior art, the system according to the present invention employs a measuring principle that does not require preparatory treatment of the rod element as is required in the known solutions. The system employs direct time of flight measurements with the aid of acoustic surface waves that are introduced into the rod element. The instrument is retrofittable on existing cylinders without any modification/ reconstruction thereof. An EMAT (6) principle is employed to introduce the surface waves into the measurement in a non-contact manner.

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会影响介质的精度，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从测量通道分离的布置，使得压力屏障的完整性不会破裂。
