20080303710 | Antenna for a Fill Level Radar for Applications Involving High Temperatures and/or High Pressures - An antenna for a fill level radar includes a high-temperature process separation device and an attenuation element. The attenuation element is used to improve the measuring signal in the near zone of the antenna and is affixed to the process separation device or in the process separation device. In this way antenna ringing may be significantly reduced. | 12-11-2008 |
20090085795 | Filling Level Radar with Variable Transmitting Power - A level measuring instrument has a variable transmitting power for measuring a filling level in a tank. The level measuring instrument includes a generator unit selectively generating different transmitting powers. The generator unit is controlled so that the transmitting power is respectively adapted to the corresponding environmental conditions. For this purpose, the generator unit has for instance two different oscillators, which are driven selectively. | 04-02-2009 |
20090128396 | Filling Level Sensor for Short Measuring Distances - A filling level sensor for a short distance measurement includes a first antenna transmitting a transmission signal to a material surface; a second antenna receiving a reception signal reflected by the material surface; and a common outer enclosure enclosing the first antenna and the second antenna. | 05-21-2009 |
20090211808 | Conductor leadthrough, housing device, field apparatus and method for producing a conductor leadthrough - A conductor leadthrough for a field device is for connecting two electrical conductors. The conductor leadthrough comprises an external conductor and a sealing apparatus. The sealing apparatus is divided into a first separation device and a second separation device. The external conductor comprises a hollow internal region that extends along a longitudinal axis of the external conductor. The first separation device and the second separation device are arranged along the longitudinal axis of the external conductor so as to be spaced apart so that they can separate a section of the hollow internal region of the external conductor. A pourable-sealing device is filled into the separated section of the hollow internal region of the external conductor so that the sealing apparatus can provide a leakage rate whose value is below a predeterminable value of a leakage rate. A signal of a predeterminable frequency can be transmitted along the longitudinal axis. | 08-27-2009 |
20100052974 | Variable Transmission Power for Fill Level Measuring - The transmission power of a fill level radar is varied in that the transmission power is switched, by a signal switch, from a first transmission power to a second transmission power. This switching takes place, for example, by bypassing the high-frequency amplifier or by switching off a drain voltage. | 03-04-2010 |
20100103024 | High Frequency Module for Filling Level Measurements in the W-Band - A high-frequency module is for fill level measuring and for use at frequencies of more than 75 GHz. The high-frequency module comprises a microwave semiconductor, a printed circuit board and a housing bonded to the printed circuit board. In order to reduce the power required, operation of the microwave semiconductor takes place in a pulsed manner. | 04-29-2010 |
20100123615 | Potential Separation for Filling Level Radar - For safety reasons the potential of an electrical supply line of a radar sensor should be separate from the potential of the filling level container. An arrangement for potential separation for a filling level radar is provided, which arrangement comprises a separation element for insulating the waveguide from the antenna. The separation element, corresponding to the cross section of the waveguide, is ring shaped. In this way rotatability between the sensor housing and the antenna subassembly is provided without influencing the signal line between the antenna and the waveguide. | 05-20-2010 |
20110057962 | DISPLAY DEVICE - Display device, with a plurality of display elements arranged in the shape of a bar, wherein each display element can represent at least one first display state (off) and one second display state (on), and a value being shown can be indicated by the second display state (on) of at least one display element assigned to the value, so that an intermediate value between the value being displayed and a succeeding or preceding value can be represented by activating the preceding or succeeding display element. | 03-10-2011 |
20120019423 | PLANAR ANTENNA WITH COVER - Provided is a planar antenna based system for use as a radar level meter, microwave barrier or other suitable system. The system includes a planar radiator element arranged on a substrate, and a cover plate element made from a dielectric to cover the planar radiator element. In one alternative embodiment, the cover plate includes a cavity proximate the planar radiator element, into which the microwaves generated by the planar radiator element can be coupled. In another alternative, the cover plate is provided in a surface-flush position against the substrate in the edge region of the cavity. These arrangements may be provided in a plurality so as to support an overall system containing multiple radiator elements. | 01-26-2012 |
20140007674 | GAS-TIGHT WAVEGUIDE COUPLING, HIGH-FREQUENCY MODULE, FILL-LEVEL RADAR AND USE - A gas-tight waveguide coupling is for coupling an electromagnetic transmission signal from a high-frequency module into a waveguide. The waveguide coupling includes a planar radiator, which is arranged on a carrier and is used for emitting the transmission signal. The waveguide coupling further includes a dielectric sealing element, which seals off the waveguide in a gas-tight manner. In this way, explosion protection can be provided. | 01-09-2014 |
20140009323 | WAVEGUIDE COUPLING, HIGH-FREQUENCY MODULE, FILL-LEVEL RADAR AND USE - A waveguide coupling includes a planar radiator element which couples the transmission signal into a waveguide of the waveguide coupling. The waveguide widens in the direction of the planar radiator element, in such a way that the radiator element can be of a comparatively large diameter without the inner walling of the waveguide detracting significantly from the signal quality. | 01-09-2014 |
