摘要:
A valve arrangement from microstructured components worked out of a basic body, for the control of fluids, include an actuation element which is movable relative to a flow path distributor and opens or closes fluid paths depending on its position. A transition from one position into the other is effected by adding an actuating drive connected to an electrical power source. The actuation element is held in its switch position. For a high fluid flow, a large force can be applied to the actuation element. The actuating drive works according to an operating principle aimed at covering the longest distance possible. A holding device is provided, which works according to an operating principle working independent of the first operating principle and provides the generation of the greatest cohesion possible.

The invention is directed to a sensor for making capacitive measurements of the pressure in gases and contains two measuring electrodes conjointly defining a capacitor and arranged in spaced relationship to each other. This sensor is improved such that a pressure measurement is possible without deformable parts. Long-term drift free measurements can be carried out with even the smallest electrode spacing being realized so that miniature sensors can be provided. The intermediate space between the electrodes is accessible to the gas to be investigated and has electrically insulating spacers between the electrodes. The spacers determine the spacing between the electrodes and maintains the electrode spacing during the measurement.

The invention is directed to a method of operating a measuring arrangement for detecting combustible gases in a gas mixture with the measuring arrangement including a display unit, a measuring unit, a detector element and a drivable compensator element. The method is improved in that the power input is minimized. This is achieved in that the detector element is supplied with the detector operating current ID during a first operating phase in the operational-ready condition; whereas, the compensator element is driven with a compensator component operating current IK1 and a first measuring signal U1 for gas analysis is formed from the voltages on the detector element and compensator element and that, in a second operating phase, the compensator element is connected in a component heat-up phase to the compensator operating current IK from the switch-in time point t0 to the time point t1 and the steady-state terminal value of the compensator voltages UK(ts) is extrapolated at the end of the heat-up phase from the increase of the compensator voltage UK(t) in the time interval t0 to t1 with a processing function and a second measuring signal U 2 for gas analysis is formed with the extrapolated terminal voltage UK(ts) and the voltage UD on the detector element.

A method for integrating a field device of automation technology into a radio network composed of a plurality of field devices, wherein the field device to be integrated switches, or is switched, at start-up, respectively, first start-up, into a special start-up mode, wherein, in the special start-up mode, a peer to peer connection to a service device or to a selected field device is produced on a specific channel and wherein integration data are transmitted from the service device or the selected field device to the field device to be integrated and/or diagnostic data of the field device are transmitted to the service device or to the selected field device.
摘要:
A method for monitoring the remaining service life of a battery used for operating a field device in automation technology. The present power consumption of the battery is ascertained. Then, during a first phase of life, power consumption of the battery ascertained during operation of the field device is compared with a predetermined threshold value. In the case of exceeding the predetermined threshold value, during a second phase of life, the battery is exposed to defined load spikes at predetermined time intervals. Voltage collapses corresponding to the defined load spikes are detected, and a warning report is generated when the voltage collapses reach a predetermined maximum limit value.
