The invention relates to a spectrometer comprising a combination of at least one grid (1) and at least one prism (2), characterised in that total reflexion is used to produce a compact spectrometer in at least one prism (2).


A sensor arrangement for determining a position and/or a change in the position of a measurement object is described, wherein the sensor arrangement (1) has a magnet (3) and a magnetic field sensor (2) which can be moved relative to one another in a direction of movement (x). The magnet (3) generates a magnetic field (5). Movements of the magnet (3) and of the measurement object or movements of the magnetic field sensor (2) and of the measurement object are coupled. In order to achieve the greatest possible measurement range with a characteristic curve which is as linear as possible at the same time, the sensor arrangement (1) comprises a rod-shaped body (4) which is made from a ferromagnetic material and has a considerably larger dimension in the longitudinal direction than in the transverse direction. A relative movement takes place between the rod-shaped body (4) and the magnet (3), wherein the rod-shaped body (4) can be connected to the magnet (3). The magnetic field from the magnet (3) is at least partially directed in the direction of the magnetic field sensor (2). In this case, the rod-shaped body (4) is arranged parallel to the direction of movement (x). The magnetic field sensor (2) is arranged on a longitudinal side of the rod-shaped body (4) and is configured to generate a measurement signal from a portion of the magnetic field (6) which emerges from the rod-shaped body (4) at the magnetic field sensor (2). As a result, the position and/or change in the position of the measurement object can be determined from the measurement signal.


The invention relates to a device serving for the combined measurement of the width and thickness of a flat object, in particular a plate, a belt, or a web. The device comprises a measurement apparatus which has at least one contactless sensor, which is for width measurement on the object and which is movable crosswise to the longitudinal direction or conveying direction of the object. According to the invention, on the opposite side of the object, there is a second sensor opposite the first sensor which, together with the first sensor, serves for thickness measurement on the object, wherein the two sensors can travel above and below the object, that is, on opposite sides of the object.


The invention relates to a device for contactless distance and/or position determination of a measurement object (1), comprising an electrically conductive measurement object (1) and a sensor (3) which is operated in particular according to the inductive, capacitive or eddy current principle, the sensor (3) comprising a measuring device (4). The invention is characterized in that the measuring device (4) is formed by at least two spatially separated measurement elements (5, 5, 5). The invention further relates to a corresponding sensor (3).

This abstract highlights the approach taken to meeting the technical requirements of the call, the partnership with two SMEs, the European dimension of the proposal, and the inclusion of universities and specialist sub-contractors. AEC has identified specific technologies (eddy current and ultrasonic acoustic sensors, and piezoelectric actuators) as having significant potential for new forms of implementation in engine controls. AEC will extend this process of engagement with specialists to ensure state of the art technology is available for aerospace controls. Specifically within this programme: - AEC will develop new means of interaction between the metering system and the sensors and actuators - Micro-Epsilon Messtechnik, a German SME, will develop an eddy current sensor system for continuous monitoring and proximity sensing - Oxford Radio Frequency Sensors, an SME closely linked to Oxford University Clarendon Laboratory, will develop piezoelectric acoustic mass flow measurement developed from recent advances in medical physics - AEC will pull through work already committed with Newcastle University to develop piezoelectric acoustic position sensing, also drawing on research work underway with Leeds University. Some of this design and manufacturing work will probably be sub-contracted to a Danish specialist company, Noliac - AEC will also pull through work already underway with Bath University to develop a new generation of piezoelectric actuators with the potential to actuate both direct drive and servo-system control of aerospace fuel systems - AEC will carry out whole system environmental testing on in house test facilities normally used for the development and qualification of civil and military fuel control systems for production application All these systems will be compact, robust, reliable, and precise by virtue of the base technologies that are being applied, and also due to the design capability within AEC to design fit for purpose aerospace controls.

An inductively operating sensor, particularly for measuring distances and positions of a metallic object, comprising at least a coil, a ferromagnetic or ferritic core and perhaps a housing comprising a sensor element, with the core being embedded in a single or multi-layered ceramic and jointly with the ceramic forming a coil body and with the coil body and the core being connected to each other in a form-fitting fashion. Furthermore, a method is suggested for producing such a sensor.


A method for measuring the thickness on measurement objects, whereby at least one sensor measures against the object from the top and at least one other sensor measures against the object from the bottom and, at a known distance of the sensors to one another, the thickness of the object is calculated according to the formula D=Gap(S1+S2), whereby D=the thickness of the measurement object, Gap=the distance between the sensors, S1=the distance of the top sensor to the upper side of the measurement object, and S2=the distance of the bottom sensor to the underside of the measurement object, is characterized by the compensation of a measurement error caused by tilting of the measurement object and/or by displacement of the sensors and/or by tilting of the sensors, whereby the displacement and/or the tilting is determined by calibration and the calculated thickness or the calculated thickness profile is corrected accordingly. The invention further concerns a device for applying the method.


The invention relates to a sensor element for an inductive sensor used for a displacement or distance measurement by means of a magnetic field that varies according to the distance from the measurement object but that remains temporally constant. In said sensor, thin ferromagnetic material is integrated into a substrate. The invention also relates to a sensor comprising said sensor element and to a method for producing the sensor element.
