摘要： A sensor arrangement for determining at least one physical parameter of a sensor unit which is activated by at least one periodic excitation, comprising a detection region in which changes of the parameter in the surroundings of the sensor unit lead to an output signal from the sensor unit. The sensor unit is wired such that if there is no change of the parameter in the detection region the output signal is a zero signal at the output of the sensor unit, whereas if there are changes of the parameter in the detection region the output signal is a signal that is not zero and which has a specific amplitude and phase. By means of a closed-loop control, the non-zero signal in the receive path is adjusted to achieve an adjusted state at zero even in the presence of changes of the parameter in the detection region. Inherent in the control signal used for this adjustment is a deviation (Δx, Δy) of the control signal from the adjusted state, which deviation represents information about the parameter. To create a sensor arrangement and a method in which values of a physical parameter in a detection region can be clearly determined, in a four-quadrant representation of the deviation (Δx, Δy) in the form of a vector analysis in a phase space of the control signal, the angle of an imaginary vector (2.6) relative to the x axis of an x, y coordinate system, said vector leading from the origin (2.7) of the x, y coordinate system to a measuring point (2.5) and said origin corresponding to the adjusted state, represents a measurement for the change of the parameter along a direction, and/or the magnitude of the imaginary vector (2.6) represents a measurement for the change of the parameter along a further direction.

摘要： A proximity sensor includes a relatively simple temperature compensation circuit, and includes a variable gain oscillator, a temperature sensor circuit, and a proximity determination circuit. The variable gain oscillator has a gain that varies with the proximity of a target to a sensor coil, generates an oscillating electrical signal having a substantially constant amplitude magnitude, and generates an energy signal representative of the electrical energy needed to sustain oscillations. The temperature compensation circuit senses proximity sensor temperature and supplies a temperature signal representative thereof, and the proximity determination circuit, based on the energy signal, supplies a proximity signal representative of target proximity to the sensor coil. The proximity determination circuit includes a comparator and a fixed resistor network. The comparator circuit supplies the proximity signal. The fixed resistor network is coupled between the temperature sensor circuit and comparator circuit and supplies a temperature compensation signal to the comparator circuit.

摘要： The invention relates to an inductive proximity sensor for embedding in a mild steel mounting plate, comprising an enclosure with a front wall of synthetic material forming a sensing face at a front end of the enclosure, an oscillator comprising a sensor coil with a core made of a material with a relative magnetic permeability larger than 1, typically a ferrite, which is arranged within the enclosure behind the front wall so that an open side of the core is directed towards the sensing face in order to direct the magnetic field of the coil towards a target in front of the sensing face, a hollow cylindrical metal member arranged perpendicular to the sensing face and surrounding the core, and a measuring circuit for measuring an attenuation of the oscillator due to eddy currents. The core is radially surrounded by a metal layer with a low electrical resistivity of less than 15 μΩ·cm and with a thickness of less than 40 μm, in order to improve the embeddability of the sensor. Alternatively, this thin metal layer may be omitted, if the electrical resistivity of the metal member is adjusted to a value in the range of 15 μΩ·cm-50 μΩ·cm.

摘要： A proximity sensor includes an L-C resonator, an oscillator for oscillating the L-C resonator, an oscillation detector, an output circuit, and a burnout detecting means. The L-C resonator has a detection coil for detecting an object, and a resonant capacitor connected across the detection coil. The oscillation detector detects an oscillation of the L-C resonator. The burnout detecting means has a time counter for counting a length of a positive voltage period in which a voltage across the resonant capacitor is kept above a predetermined positive voltage, and a discriminator which determines burnout of the detection coil when the counted length exceeds a half of an oscillation cycle of the L-C resonator. The output circuit outputs a detection signal indicative of whether or not the object exists within a detection range of the detection coil, and provides a burnout signal indicative of the burnout of the detection coil.
