摘要:
A plug-in module for a liquid- or gas-sensor comprised of a sensor module (SM) and a sensor module head (SMH), which can be releasably connected together, and which, when connected, enable data and energy transfer via a galvanically decoupled transfer section, wherein the sensor module head (SMH) includes an energy supply unit for operating the sensor module head (SMH) and the sensor module (SM), as well as a data memory (MEM), in order to store sensor data received from the sensor module (SM).
摘要:
A method for calibrating and/or adjusting a sensor, especially an electrochemical, electrophysical or optical sensor, wherein the sensor has an evaluating electronics, which is embodied in such a manner, that a signal produced by the sensor is essentially non-changeable by a subsequent transmission. The sensor is calibrated and/or adjusted at a site other than a later measuring location or a later measuring environment or the like.
摘要:
In a method for compatibility checking of a measuring system including a measurement transmitter and a sensor, a first signature is externally created for an identifying data set and is stored in the measurement transmitter. After transmission of the identifying data set from the measurement transmitter to the sensor, a second signature is calculated for the identifying data set in the sensor. If the signatures match, then the measurement transmitter and the sensor are compatible and the measurement transmitter can access data and/or functions of the sensor.
摘要:
A process automation system for determining, monitoring and/or influencing different process variables and/or state variables in at least one manufacturing or analytical process. Included is: at least one control station; and a plurality of field devices; wherein in each field device at least one sensor is provided for ascertaining a measured value of a process variable and/or state variable and/or an actuator is provided for influencing a process variable and/or state variable by means of an actuating value. Each field device makes available its cyclically or acyclically ascertained, measuring-device-specific, measured values and/or actuating values of the process variable and/or state variable to every other field device of the process automation system as information, and the current information of all ascertained measured values and/or actuating values of the process variables and/or state variables is available to each field device as a current process-state-vector.
摘要:
The inventive modular measuring transducer is used for galvanic separation of the modules of said transducer and for avoiding the use of data transmission channels and comprises a sensor module for detecting a measured value, and an electronic module. Said sensor module and electronic module are connected to each other by means of a contactless interface, thereby making it possible to power the sensor module, and to carry out the data exchange between the sensor module and the electronic module. In addition, said electronic module comprises a receiver-transmitter for wireless data interchange with an additional transmitting or receiving-transmitting station.
摘要:
A symmetrically wired device and a process for measurement of the concentration of ions, especially hydrogen (H+) ions, in a measurement liquid. The device comprises a pH-sensitive measurement electrode, a reference electrode and a comparison electrode, all located in the measurement liquid and which places the measurement liquid at a definable ground reference. The device forms a difference signal referenced to the ground reference from the difference between a measurement signal (φpH) of the measurement electrode and the reference signal (φref) of the reference electrode. The difference signal is dependent on the ion concentration in the measurement liquid. The device compensates for the noise potential (φchem) arising between the comparison electrode and the measurement electrode by setting a reference potential (φbez) on the comparison electrode, such that φref assumes a zero value.
摘要:
A field device for process automation, composed of at least two components coupleable with one another, wherein, in each of the components, a control/memory unit is provided, in which, in each case, a parameter set with defined parameters is stored, and wherein, for the case, in which the at least two components are coupled with one another, at least one of the control/memory units reads, and compares with one another, the parameter sets stored in the separate control/memory units of the components, and wherein, in the case of a deviation in the parameter sets, the comparing control/memory unit of the control/memory units makes available, to the components coupled with one another, the intersection of the parameters of the parameter sets.
