Embodiment Construction
[0028] attached figure 1 A schematic diagram of an embodiment of the device of the invention is shown. A filling substance 7 is present in a container 8 . For determining the fill level of the filling substance 7 is a fill level measuring device 17 which is fitted in the opening 19 of the lid 16 of the container 8 . The measurement signal generated by the signal generation unit 1 and connected via the drop-in / drop-out unit 2 is radiated via the antenna unit 3 in the direction of the surface 6 of the filling substance 7 . The transmitted signal is partially reflected on the surface 6 as an echo signal. The echo signals are received by the antenna unit 3 , are tapped out via the drop-in / drop-out unit 2 , and are evaluated in the control / evaluation unit 9 . In combination with the control / evaluation unit 9 is a delay circuit, eg as described in DE 31 07 444 A1. Correct clocking of the transmission of the transmitted signal and the reception of the echo signal occurs via the t...

The invention relates to a device for determining or monitoring the filling level of a filling material (7) stored in a container (8) in a process, having a signal generation unit (1) which generates radio-frequency measurement signals, having a coupling-in / coupling-out unit (2) which couples the radio-frequency measurement signals into an antenna unit (3) and couples said measurement signals out of the antenna unit (3), wherein the antenna unit (3) has a waveguide (4) and an antenna element (5) which widens in the direction of the filling material, wherein the antenna unit (3) emits the radio-frequency measurement signals in the direction of the surface (6) of the filling material (7) and receives the echo signals reflected at the surface (6) of the filling material (7), and having a control / evaluation unit (9) which uses the transit time of the measurement signals to determine the filling level of the filling material (7) in the container (8), wherein a process separation (10) is provided in or on the antenna unit (3), which process separation is at least approximately transparent to the radio-frequency measurement signals and protects the coupling-in / coupling-out unit (2) from influences of the process, wherein the process separation (10) is an isostatically pressed moulded part which is produced from at least two plastics (11, 12) having different physical and / or chemical properties.
Description
technical field [0001] The invention relates to a device for determining or monitoring the filling level of a filling substance located in a container during a process, comprising: a signal generating unit, which generates a high-frequency measurement signal; an input / output unit, which connects the high-frequency measurement signal An incoming antenna unit or an outgoing antenna unit, wherein the antenna unit has a hollow conductor and an antenna element that widens towards the filling material, via which antenna unit high-frequency measurement signals are emitted in the direction of the filling material surface and are received The echo signal of the measurement signal; the control / evaluation unit determines the fill level of the filling substance in the container based on the travel time of the measurement signal. In or on the antenna unit, a process isolator is provided which is at least approximately permeable to the high-frequency measurement signal and which protects th...
