Abstract

A system for measuring the position of a rod element 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 principle is employed to introduce the surface waves into the measurement in a non-contact manner.

Abstract

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.

DEVICE FOR TRANSFER OF ELECTRICAL SIGNALS AND/OR ELECTRICAL ENERGY

Abstract

The present invention relates to a system for transmitting electrical signals and/or electrical energy via an electrically conductive medium (7). An eddy current is created when a time-variable current is applied to an electric wound coil (1, 3), in the form of a band with conductor paths extending parallel to the surface of the electrically current-carrying medium, thereby creating a magnetic field which penetrates the surface of the electrically conductive medium (7). Since the magnetic field varies with time, an electric field will be generated which is oriented at 90 degrees to the magnetic field. This electric field will generate a potential difference between an upper and lower part of the electric wound coil (1, 3). The electric field will cause a movement of electrons, thereby creating a flow between the upper and lower part of the electric wound coil (1, 3). This time-variable flow of electrons will attempt to equalize the potential difference by electrons flowing back on the opposite side of the electrically conductive medium (7), thereby creating a circulating flow between an external and an internal surface of the electrically conductive medium (7). Since a flow is created on the opposite side of the generating electric wound coil (1, 3), this flow will form a magnetic field which in turn induces a voltage in the adjacent electric wound coil (1, 3). The system is omnidirectional and acts in both directions.

Abstract

The invention relates to a type of shock and vibration isolator which has almost identical rigidity and damping properties in any translatory direction, wherein the device is disposed between a reference object (A) which is subjected to vibrations and shocks, and a means (B) which is only to be subjected to translatory damped vibrations and shocks in all directions, where a centre bar (2) and wire rope holders (3) are designed for attachment to any one of the reference objects (A) or (B), characterised in that the centre bar (2) and the wire rope holders (3) are rigidly interconnected to three or more independent wire rope series (4), each of which is formed of two or more wire rope loops where the configuration of a wire rope series (4) is based on essentially as many wire rope loops with opposite geometrical angles of inclination (A1 and A2), each wire rope series forming a symmetry along a centre axis relative to an unloaded neutral position for the isolator and where the three or more wire rope series (4) are symmetrically arranged about the centre axis in an about-axis symmetry principle relative to the radial neutral position of an unloaded isolator, such that the two symmetry principles together give almost identical translatory properties in all directions for damping of shock and vibration between the reference objects (A) and (B).
