摘要： The method of the present disclosure is used to monitor a condition of a measurement sensor comprising an oscillator, which has a measuring tube for conveying the medium, and a condition parameter dependent upon a further physical parameter. The method comprises: determining tuples containing a value of the physical parameter and an associated value of the condition parameter; assigning the tuples to a value range of the physical parameter; and forming a reference value of the condition parameter for this value range of the physical parameter using the value of the condition parameter when no valid reference value of the condition parameter for this value range is present; or comparing the value of the condition parameter of the tuple with the reference value when a reference value of the condition parameter for this value range is present; and generating a finding on the basis of the result of the comparison.

摘要： The present disclosure relates to a thermal flowmeter comprising at least one measurement sensor having at least one sensor element for determining a measured value for determining the flow rate of a medium. A measurement transducer determines the flow rate using the determined measured value. A tubular connecting element connects the measurement sensor to the measurement transducer and a protective sleeve is provided, which is mechanically connected to the tubular connecting element. The protective sleeve has a sleeve casing having at least two openings, an inflow opening through which the medium can be delivered to the measurement sensor and an outflow opening through which the medium can flow out of the measurement sensor. The connection between the protective sleeve and the tubular connecting element is a connection which is positively engaged at least in part.

摘要： The present disclosure includes a method for producing a printed circuit board having at least one coating includes mixing a first component with a second component of a two component coating system to form a coating mixture by means of a dynamic mixer or by means of a static-dynamic mixer. The method also includes supplying the coating mixture to an output unit, and coating the printed circuit board by outputting the coating mixture using the output unit onto the printed circuit board. The output unit is moved automatically in at least one, two, or three dimensions relative to the printed circuit board. The mixer is connected with the output unit in such a manner that it is moved together with the output unit relative to the printed circuit board. The present disclosure also includes a coating head for performing the method.
