Abstract: A measurement system for a construction machine, in particular a road construction machine including a temperature measuring device and an evaluation device. The temperature measuring device is configured to determine a first surface temperature for a first area of a measuring field as well as a second surface temperature for a second area of the measuring field, the temperature measuring device being directed to a reference surface, in relation to which the construction machine is moving, and the measuring field being shifted as a function of a movement of the construction machine along the reference surface. The evaluation device is configured to determine a movement parameter by means of a shift in a first temperature zone, defined for a first point in time by the first surface temperature within the first area, in relation to the first and/or second area(s) or in relation to the measuring field.

Abstract: A device for determining the temperature of a road building material applied by a construction machine in a mounting width is arranged at the construction machine in a range within the mounting width and has an infrared temperature measuring head, a motor and a controller, the infrared temperature measuring head being arranged to be twistable by the motor transverse to the direction of travel of the construction machine and being effective to record temperature measuring values of the surface of road building material during a rotational movement at at least two measuring points spaced apart from one another. The controller is effective to control the motor based on the fitting position of the device at the construction machine such that the distance between the measuring points on the surface to be measured remains equal.

Abstract: The invention relates to a system for pulse magnetizing high-precision magnetic scales. The system comprises a shaped current conductor (1) and a pulse current source (2) that is composed of a capacitor bank (3), a transfer switch (4) and a control unit (5). The compact set-up of the system is the prerequisite for a power circuit that has such a low resistance that the required high pulse currents are obtained at supply voltages of below 60 V. The transfer switch is an H bridge with four switches (7) that contain equal numbers of MOS transistors connected in parallel. The short pulse times that are achieved using the MOS transistors allow the use of shaped current conductors with which magnetized areas can be produced with a very high precision. The inventive system provides a means for saving components, electric power and time by a factor of up to 100.
