[0008] Even if this plug-in module is relatively simple in structure, the use of the plug-in module in the method for testing the performance of process equipment is relatively simple with respect to having an input function (by means of which the operator can directly check the position of use of the plug-in module). The use of simulators for determining the measured values to be simulated) has the disadvantage that tests can only be performed for certain measuring chains with a limited number of measuring tasks

Embodiment Construction
[0033] in figure 1 A test device 1 is shown in, by means of which the test chain of the process equipment can be tested. In the following, the corresponding test method is explained with the help of the measuring chain used for measuring pH, but the present invention should not be limited to the measuring chain used for measuring pH. As mentioned above, the method can be applied in the same way to other measurement parameters and measurement tasks such as conductivity measurement, gas sensing mechanism or temperature measurement chain, as long as there is a measurement switch with a corresponding sensor interface Energy device.
[0034] The measuring transducer 3 has a housing with a key switch 4 and a spin switch 5 (so-called micro switch) as an input element and a display 7. With the help of switches 4 and 5, the operator can select different menus on the display 7. In addition, the measurement transducer 3 can be connected to a higher-level unit (not shown) such as a proces...

A method for testing the behavior of a process plant as a function of the signals of a sensor, wherein the process plant includes at least one measuring chain with a measurement transmitter, which converts the sensor signal and outputs a measured value, and which has at least one sensor interface for connection of the sensor, wherein the method includes steps as follows: connecting a sensor simulator to the sensor interface for forming a test arrangement; selecting, by means of an input function on the measurement transmitter, a sensor signal to be simulated or a sequence of sensor signals to be simulated; transmitting from the measurement transmitter to the sensor simulator a selection signal corresponding to the selected sensor signal to be simulated or the selected sequence of sensor signals to be simulated; and transmitting from the sensor simulator to the measurement transmitter a simulated sensor signal assigned to the selection signal or a sequence of simulated sensor signals assigned to the selection signal.
Description
Technical field [0001] The present invention relates to a method for testing the performance of a process device based on a signal from a sensor, wherein the process device includes at least one measuring chain having a measuring transducer for converting sensor signals and emitting measured values And the measuring transducer has at least one sensor interface for connecting the sensor. Background technique [0002] In the context of the present invention, the measuring chain means the transmission path that transmits the initial sensor signal according to the parameter to be measured to the measuring transducer that receives the sensor signal or the adjusted sensor signal, so as to further process the sensor signal, which is particularly convenient The measurement value is obtained from the sensor signal. The measurement transducer has a sensor interface through which the measurement transducer is connected to the sensor during measurement operation. In addition, the measureme...
