Heat-generating plants are used in industry and in heating technology. The safe operation of such plants requires a large number of safety devices. They are designed to prevent, among other things, excess temperature, overpressure and vacuum. In the area of temperature …
When a constant current is passed through a thermometer of resistance Rt and a fixed reference resistor of known value Rs, the voltage across them will be in direct proportion to their resistance values. The ratio of the two voltages and therefore of the two …
In temperature calibration technology, there are two methods of calibration - the comparative calibration and the fixed point calibration. The method of calibration to be used will be defined through the demands on the accuracy and the type of test instrument. The …
Temperature - a term that we use almost daily as a matter of course, without being made aware of the physical correlations. But how is the term temperature defined? Everybody perceives temperature in their environment purely subjectively. If we are too warm or too …
In general usage, the term "verification" is often mixed up with "calibration". In contrast to calibration, where the deviation of a measured value is determined and certified from a standard, verification goes well beyond that and is only in very special cases a legal …
