FILLING LEVEL MEASURING DEVICE OPERATING WITH MICROWAVES, HAVING AN INSERT COMPOSED OF A DIELECTRIC, AND PROCESS FOR PRODUCING THE DIELECTRIC |
摘要 |
A description is given of a filling level measuring device operating with microwaves, having a housing and an insert composed of a dielectric, and of a process for producing the dielectric, in which the dielectric constant of the insert is adjustable and in which the insert has a high chemical resistance and a mechanical strength adequate for industrial applications. The dielectric is a composite material composed of a fluoroplastic, in particular polytetrafluoroethylene, and ceramic and is produced by mixing powdered ceramic and powdered fluoroplastic, drying the mixture, pressing the mixture and sintering the pressed mixture.
