Abstract
Official abstract text for this publication.
A field device electronics for a conductive, limit-level switch, with a conductive probe and a measuring circuit including a control/evaluation circuit. The measuring circuit, a measuring bridge circuit is present, with at least one coupling capacitor (C2) being present for the DC voltage separation of the probe from the measuring circuit, and with the at least one coupling capacitor (C2) being integrated into the measuring bridge circuit.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus embodied to measure the limit level of a fluid in a container, comprising: an electronic field device; at least one conductive probe projecting into the container; and a measuring circuit with a control/evaluation circuit, wherein: said control/evaluation circuit supplies said measuring circuit with a measurement voltage which is an alternating-current voltage; said measuring circuit includes a measuring bridge circuit, with a prob…
