摘要： Disclosed is an arrangement for detecting rotational speed of a wheel or any other rotating body by a sensor (1, 6), which is coupled via a magnetic field to an encoder (23) that rotates with the rotating body. If a slot between sensor element (S1, S2) and encoder (23) becomes too small in the prior art arrangements, flipping and, hence, doubling of the measured rotational speed of the wheel can occur. This caused problems in safety devices of a vehicle, which require a correct indication of the wheel rotational speed for proper operation. To improve the tolerance with respect to the mounting position of the known arrangements, two separated signal paths (S1, f1; S2, f2) are provided with sensor elements (S1, S2) of differing sensitivity. The signal paths (S1, f1; S2, f2) are designed so that a signal path (S1, f1) is always available, which is provided with a maximum rate of sensitivity so that, in the undisturbed normal case, minimum image defects of the encoder track (13) are achieved, simultaneously with maximum air slots, while at the same time there is always an observing signal path (S2, f2), whose sensitivity is rated in such a way that flipping is safely prevented in all magnetic conditions.

摘要： Disclosed is an arrangement for the intrinsically safe detection of movements of a body, such as a wheel. The arrangement includes a magnetic encoder (5, 25) and a sensor (26), the magnetic encoder (5, 25) moving with the body and is magnetically coupled to at least two sensor elements (S1, S2) of the sensor (26) via a magnetic air gap. The sensor (26) has at least two mutually separate signal paths (S1, f1; S2, f2) which have at least one of the sensor elements (S1, S2) and a signal conditioning stage (28, 29). A primarily measuring signal path (S1, f1) is constructed so that during normal operation represents an output signal the basic frequency of the encoder movement or the temporal profile of the output signal have patterns. The temporal occurrence of the patterns correspond to the basic relative speed between the sensor (26) and the pole pairs of the encoder (5, 25) which are detected by the sensor.

摘要： The pressure in a motor vehicle tire can be determined by means of a ‘wheel-independent’ device (1) that is in a largely rigid manner connected mechanically to an element (2) of the vehicle body (3, 14) oscillating with the motor vehicle wheel (4). In order to determine the—preferably absolute—tire pressure by combining the evaluation of rotational speed data and axle frequency analysis, said device (1) includes a signal pre-processing element (6) provided with electronic components for processing the sensor signals, said element being connected to a magnetic sensor element (7) and an acceleration sensor element (8) or to a combined magnetic/acceleration sensor element (5) by means of an electrically conductive element connection (9), wherein the magnetic sensor element (7) or the magnetic/acceleration sensor element (5) is operatively connected to a magnetic encoder (16) arranged on the wheel side. To improve determination of characteristic quantities, preferably the vibration behavior of at least two wheels (4) is analyzed.

摘要： The present invention relates to a method for checking or determining the installation air slot between an active sensor and an encoder, wherein the maximum size of the air slot (maximum air slot) which still ensures trouble-free operation of the sensor depends on the level of the supply voltage of the sensor at least within a range of said supply voltage, and which is more particularly characterized by the following method steps: reducing the supply voltage of the sensor to at least one value by which the maximum air slot is each time decreased by a desired test measure, and comparing the at least one test measure with a desired difference between the maximum air slot and the existing air slot by sensing a variation of the sensor output signal by the reduction of the supply voltage, as well as evaluating the comparison result by signaling and/or storing. A corresponding device is also described.

摘要： An arrangement for sensing the rotational speeds of a wheel or any other rotating member includes a sensor module with a sensor element, a controllable current source with a modulator and a signal conditioning and evaluating circuit. The modulator controls the current source in response to the signals of the sensor element and/or external signals and, as an output signal of the sensor module, delivers a current signal representative of the rotational behavior with status or additional signals superposed on the current signal. The evaluating circuit of the sensor module includes at least two different signal-conditioning networks which, by way of a control network, in dependence on predetermined criteria or conditions, are connected between the sensor element and the modulator controlling the current source and take care of signal conditioning. The shift from one signal-conditioning network to another occurs in response to control signals which the control network derives automatically from the control of one of these networks, or in response to control signals which are sent to the control network by a signal-receiving external circuit outside the sensor module via the same signal line.

摘要： A process and a system for multi-channel gathering and evaluation of measured data in which measured data channels are distinguished into analog data channels and into digital or event channels. By means of a signal derived from the events, or rather from event signals, and processed in the event channels the analog measured data are synchronously sampled, (i.e. picked up, converted into a digital value and stored). Each time an identification number is stored for the event signal triggering the sampling operation, or rather of the corresponding event channel, the phase time between this sampling signal and the preceding sampling signal, the associated sampled measured data and the time sequence of the sampling operations. The signal triggering the synchronous sampling operation is preferably formed by OR-linking of all event signals which are scaled down, if applicable.
