Maximum permissible operating pressure
mer
Is the maximum permissible pressure of the working medium defined by the manufacturer for which a component or device is designed and at which the function and operational reliability are still guaranteed.
The maximum permissible operating pressure is always dependent/interactive with the maximum permissible operating temperature and ambient temperature. The interactions in plastic pressurised components are so strong that they must be taken into account and might mean that they cannot be used. In other cases the interactions must at least be checked. A reference temperature for the working medium and the environment of 20 °C usually serves to determine the maximum permissible operating pressure defined by the manufacturer. If the actual temperature of the working medium or the environment deviates from the manufacturer reference, the user must limit the maximum operating pressure accordingly or use more stable components. If the maximum operating pressure is permissible at simultaneously high temperatures, the manufacturer will define this accordingly in the documentation.

Maximum permissible operating temperature
mer
Is the maximum permissible temperature of the working medium defined by the manufacturer for which a component or device is designed and at which the function and operational reliability are still guaranteed.
The maximum permissible operating temperature is always dependent/interactive with the maximum permissible operating pressure and prevailing ambient temperature. The interactions in plastic pressurised components are so strong that they must be taken into account and might mean that they cannot be used. In other cases the interactions must at least be checked. A reference pressure for the working medium and an ambient temperature of 20 °C usually serves to determine the maximum permissible operating temperature defined by the manufacturer. If the actual pressure of the working medium or the ambient temperature deviates from the manufacturer reference, the user must limit the maximum operating temperature accordingly or use more stable components. If the maximum operating temperature is permissible at simultaneously high operating pressure and/or increased ambient temperature, the manufacturer will define this accordingly in the documentation.

Measurement
mer
Measurement device
mer
Is a device which continuously measures a mathematical, geometrical, chemical, physical or time variable directly (e.g. thermometer) or indirectly (e.g. turbine flow transmitter), processes it internally in a suitable form if necessary and shows it in a display.
Short definition: measurement is sensing and if necessary processing and displaying.
mindre

Measuring transducer
mer
Is a device which continuously measures an electrical variable on the input side, converts it internally and provides it on the output side in another electrical variable as a signal for further processing (e.g. 2-wire measuring transducers which pick up a physical variable on the input side by a potentiometric sensor and provide it as a current signal for further processing on the output side).
