摘要： The invention relates to an apparatus for monitoring a field device for determining and/or monitoring a physical and/or chemical process parameter of a process medium with a first sealing stage facing toward the process and at least one housing with a predetermined interior volume. The housing is located on the side of the first sealing stage facing away from the process, wherein energy is transferable through the first sealing stage 4 in the direction of the process medium. This energy interacts with the process medium, wherein at least one detector unit is provided in the housing, which unit monitors at least one condition parameter of the interior volume of the housing. A control/evaluation device determines, on the basis of the energy interacting with the process medium, the physical and/or chemical process parameter, and wherein the control/evaluation unit and/or another monitoring unit recognizes and/or seals off and/or issues an alarm, on the basis of the monitored condition parameter in the interior volume of the housing, as soon as the monitored condition parameter in the interior volume of the housing a predetermined limit value.

摘要： An ultrasonic converter (1) is proposed with a housing (5) and a cylindrical ceramic oscillator (2) of slight thickness with metal electrodes (7, 8), arranged at the front faces of the ceramic oscillator (2) and an adaptation layer (3) made of a synthetic material arranged between the front face of the ceramic oscillator (2) facing the irradiating medium and the membrane (6) of the ultrasonic converter (1) formed by the floor of the housing. The remaining free space of the housing (5) is filled with a synthetic damping layer (4) for damping the ceramic oscillator [2]. The innovation of the invention lies in that the damping layer (4) is formed from a silicon elastomer of high density with a large proportion of metal oxide, which can be mixed and applied mechanically during the gel phase of the adaptation layer (4).

摘要： In an assembly for signal transmission between a transmitter location and a receiver location connected to each other by a two-wire conductor an analog signal current, variable between two limit values, flows via this two-wire conductor. This signal current represents a measured variable sensed by a sensor in the transmitter location and forms the supply current necessary for operating the transmitter location. The transmitter location comprises a circuit generating a constant operating voltage for the transmitter location. Also provided in the transmitter location is a controllable current source being provided, determining the current flowing via the two-wire conductor as a function of the measured variable. The circuit generating the operating voltage for the transmitter location is a switching regulator and in the transmitter location a controllable voltage regulator is provided, the output voltage of which changes in the opposite sense of the signal current and forms the input voltage of the switching regulator.

摘要： A fill level measuring device. On a plurality of different signal paths, microwave signals can be transmitted into a container, and their associated echo signals recorded. The device includes: measuring device electronics having a microwave generator for the successive production of microwave signals; and, connected thereto, a frequency-selective, passive antenna arrangement, which has a number of frequency-selective elements—especially bandpass filters—in each case transmissive for one of the different wanted frequencies. Via the antennas and the frequency-selective elements, for each of the different microwave signals and its echo signal, a uniquely associated signal path is specified, via which a microwave signal is transmitted into the container and its echo signal, reflected back to the antenna arrangement, is received and fed to the measuring device electronics. The device also includes an apparatus, which is provided in the measuring device electronics and which associates successively arriving echo signals with the associated signal path.
