MEASURING DEVICE FOR A SUCTION BELT CONVEYOR AND SUCTION BELT CONVEYOR WITH A MEASURING DEVICE

摘要

The invention relates to a measuring device for a suction belt conveyor of a strand machine of the tobacco processing industry for conveying material, in particular tobacco, the suction belt conveyor having at least one strand guide channel (16) open to the outside, preferably downwards, the cavity (16c) of which is provided by two lateral channel cheeks (16a, 16b) and a suction belt (17) along a conveyor path, the measuring device being provided for determining properties of the material conveyed along the conveyor path and having a body (100), at least one microwave measuring device and at least one resonator cavity (118) , wherein the body (100) has a first end face (100a) and an opposite second end face (100b) and an opening (104) which opens into both end faces (100a, 100b) and is open towards the outside, preferably in the installation position of the measuring device and is designed so that the body ( 100) in the installation position of the measuring device with alignment of the opening (104) to the cavity (16c) of the strand guide channel (16) with one of its end faces (100a, 100b) can be arranged on the strand guide channel (16) or with its two end faces (100a, 100b) can be fitted into the strand guide channel (16), and the resonator cavity (118) within the body (100) is formed adjacent to the opening (104) and is open to the opening (104) via at least one measuring window (108). The special feature of the invention is that the microwave measuring device is subdivided into at least one high-frequency unit (130, 132) and into a processing unit (134) and the at least one high-frequency unit (130, 132) adjacent to the opening (104) and the processing unit (134) from the opening (104) is arranged on and / or in the body (100).
