Measuring device for determining and/or monitoring process variable e.g. temperature, of medium e.g. liquid, has resistor line and electrode line consecutively aligned such that condenser is made by electrode line and resistor line

摘要

The device has a resistor line (1) and an electrode line (2) consecutively aligned such that a condenser is made by the electrode and resistor lines. A temperature measuring unit (3) determines and/or monitors temperature by the resistor line. A capacitance measuring unit (4) determines and/or monitors the capacitance of the condenser. The resistor line is designed in a form of a loop in sectionwise. The electrode line is arranged at a center in the loop in sectionwise. The resistor and electrode lines are partially covered by a layer, which is partially made of moisture-dependent polymer.
