Apparatus for determining and/or monitoring at least one physical or chemical process variable of a medium in a containment comprising at least one sensor element, at least one housing module and at least one flange, wherein the sensor element and the flange are connected with the housing module, wherein the flange in a first portion, which is at least partially media contacting, is manufactured at least partially of a first material, which is selected application specifically, and wherein the flange in a second portion, which is at least partially environment contacting, is manufactured at least partially of a synthetic material.

Hybrid flange

A method for operating a measuring apparatus, comprising the steps as follows: ascertaining a flow velocity; comparing the ascertained flow velocity with a threshold value, which corresponds to a critical loading, especially to a resonant frequency, of a measuring apparatus immersion body protruding into the flow; and outputting a report, which signals reaching of a critical flow and/or frequency.

Method for operating a measuring apparatus

The invention relates to an apparatus for the calibration of a thermometer in situ, wherein the apparatus has a temperature sensor (S) for determining a temperature (T); wherein a reference element (K) is provided for calibrating the temperature sensor (S); wherein the reference element (K) at least partially comprises a ferroelectric material (D), which experiences a phase transformation at at least one predetermined temperature (T) in a temperature range relevant for calibrating the temperature sensor (S).

Method and apparatus for calibrating a thermometer in situ

A sensor element, comprising first and second measuring paths, wherein the first measuring path extends via a first segment of a first material and the second measuring path at least partially extends via this first segment of the first material, wherein the second measuring path extends additionally via a second segment, which is composed of a second material different from the first material.

Sensor element, thermometer as well as method for determining a temperature

The invention relates to an apparatus for the calibration of a thermometer in situ, wherein the apparatus has a temperature sensor (S) for determining a temperature (T); wherein a reference element (K) is provided for calibrating the temperature sensor (S); wherein the reference element (K) at least partially comprises a ferroelectric material (D), which experiences a phase transformation at least one predetermined temperature (T) in a temperature range relevant for calibrating the temperature sensor (S).

A temperature measuring insert composed of ceramic or sintered materials of magnesium oxide or aluminum oxide accomodates, on its end facing the measured medium, temperature sensor elements, such as thermocouples and temperature measuring resistors, as a measuring tip, installable singly or with others in metal or ceramic protective tubes. The site of the measuring tip, a water adsorption behavior differing from the remaining measuring insert material is present, in order to protect the temperature sensor elements in the case of rapid process related temperature changes, in order to prevent, in the case of heating, effects due to superheated steam. A solution is provided by features including that the measuring insert has a jacketing comprising densified desiccant coatings, which have a gradient with a continuously or stepwise adapted water adsorptive behavior in the direction of the temperature sensor element, wherein, for example, a decreasing water adsorption is realized according to the invention by means of different fractions of modified and unmodified adsorbents as well as hydrophobic, super hydrophobic or hydrophobized ceramic parts.

Measuring insert for temperature measurement

A thermometer with protective tube inner part for insertion into a protective tube, especially a protective tube of a thermometer, wherein the protective tube inner part serves for arranging conductor elements, and wherein the protective tube inner part is matched to the shape of the inside of the protective tube in the region of a closed, protective tube end, and wherein the protective tube inner part serves to arrange the conductor elements on the side of the protective tube inner part facing the protective tube in the installed state.

Protective tube inner part for a thermometer with a protective tube

An apparatus for connecting a measuring transducer with a control/evaluation unit, wherein at least one clamping apparatus is placed on a molded part. The clamping apparatus serves for producing a connection between at least one connecting line of the measuring transducer and at least one connecting line of the control/evaluation unit, wherein a soldering tab is provided, which serves for producing a soldered connection between the connecting line of the measuring transducer and the clamping apparatus, and wherein the soldering tab is embodied at least partially in such a manner so as, and serves, to damp possibly occurring vibrations.

Connection terminal block

A resistance temperature sensor with a first temperature sensor element and a second temperature sensor element, wherein the first temperature sensor element comprises a first measuring path and the second temperature sensor element a second measuring path, wherein the first and the second measuring paths extend on a substrate, wherein the substrate has an anisotropic thermal expansion with at least two mutually differing expansion directions (a, c), and wherein a projection of the first measuring path on the expansion directions (a) differs from a projection of the second measuring path on the expansion directions (c).

Resistance temperature sensor

A gas analyzer for continuously determining the concentration of a gas in a gas mixture, having a measuring cell, a radiation source, a detector and signal processing facilities, characterized in that the radiation source is slidingly arranged in the measuring cell.
