Embodiment Construction

[0033] The sensor 1 comprises at least one measured sensor element for the automation of the detection process. The sensor 1 is then for example a pH sensor, also known as an ISFET - usually an ion-selective sensor, which is a sensor for measuring redox potential, measuring e.g. wavelengths in the UV, IR and / or visible range Absorption of electromagnetic waves in the medium, measurement of oxygen, measurement of conductivity, measurement of turbidity, measurement of the concentration of non-metallic materials or measurement of temperature, and measurement of their corresponding measurands.

[0034] figure 1 Such a sensor is shown, which comprises at least one metallic segment 8 .

[0035] The sensor 1 is at least partially immersed in the medium 2 to be measured. This leads to the media contact section 6 . The metal section 8 can also at least partially form the dielectric contact section 6 . The medium-contact section 6 of the sensor 1 comprises at least two distinct regi...

Abstract

The invention relates to a sensor (1) in the field of process automation and the production thereof for detecting a measurement of a medium (2), said sensor (1) comprising at least one metal section (8) comprising a coating having a diamond-like carbon layer (7). In addition, the invention also discloses a corresponding method.

Description

technical field [0001] The invention relates to a process automation sensor for detecting a measurand of a medium. The invention also relates to the production of sensors for this process automation technology. Background technique [0002] Sensors for analytical measuring technology are used in a wide variety of media, especially liquids. In many embodiments, steel components are used in combination with other materials for contact with the media. [0003] This can cause problems such as corrosion. Contents of the invention [0004] The aim of the present invention is to overcome these problems. [0005] This object is achieved by a sensor comprising at least one metal section which at least partially comprises a coating with a diamond-like carbon layer. [0006] " Kohlenstoffschicht" is the English term for a "diamond-like carbon" layer or DLC. [0007] The coating improves eg sliding properties so that less media remains stuck to the sensor. [0008] Furthermore...
