Abstract: A method for installing a fiber-optic sensor in a protective tube, wherein a reshapable filler element which is preferably a wire made of spring steel is used as the filler element that, when twisted assumes an essentially helical shape, is introduced into the protective tube essentially in parallel to the axis of the fiber-optic sensor, where by changing the shape of the filler element, the free internal cross-section of the protective tube remaining for supporting the fiber-optic sensor is reduced such that the sensor is pressed against the wall of the protective tube whereby the thermal interface between the protective tube and sensor is improved and the reaction time during temperature measurements is reduced.

Abstract: A measurement transducer having a sensor for converting a physical or chemical variable into an electrical signal which can be further processed, and an electronics unit proximate the sensor, for pre-processing the electrical signal and generating a measurement signal, wherein an evaluation device is connected to the receiver by an interface for transmitting the measurement signal and serves to determine a measurement value as a function of the measurement signal and output the measurement value, and so that the sensor can be operated at a relatively high temperature and the electronics unit arranged proximate the sensor, for reducing measurement noise is operable at a relatively low temperature, the electronics unit proximate the sensor, is provided with a thermal insulation with respect to the sensor and is cooled by a heat pipe, and where the evaluation device housing approximately at ambient temperature preferably serves as a heat sink.

Abstract: A Coriolis mass flow measuring device, comprising at least one measurement pipe, through which a medium flows and which is induced to vibrate by an exciter arrangement, wherein two optical vibration sensors, arranged before and after the exciter arrangement in the longitudinal direction of the at least one measurement pipe, provide vibration signals, based on which an activation and evaluation device determines the mass flow and/or the density of the medium. The optical vibration sensors each have a pair of superimposed grids having periodic structures to improve the resolution that can be achieved by the optical vibration sensors.

Abstract: A binary data transmission system uses a code consisting of n-bit code words of a quasi-cyclic code with k information bits and n-k check bits. An encoder and a decoder with an error-detection and -correction facility are provided which use a quasi-cyclic code that has a high error-correcting capacity and requires little storage space.
