Abstract: The present disclosure relates to an apparatus the for verification, calibration, and/or adjustment of a measuring instrument. The apparatus includes the measuring instrument, a reference measuring instrument, and a smart device. The apparatus performs a measuring operation in which the measuring instrument determines a value of a variable of the medium and the reference instrument determines a reference value of the variable from a sample of the medium. The measuring instrument communicates wirelessly and performs the verification, calibration, and/or adjustment on the basis of the measured value and the associated reference value. The reference measuring instrument is portable and communicates wirelessly with the smart device and the measuring instrument. An application executed on the smart device controls a data transfer between the measuring instrument, the reference measuring device, and/or the device that is required for executing the verification, calibration, and/or adjustment.

Abstract: The present disclosure relates to a method for operating a measurement site for determining at least one measurand of a medium, wherein the measurement site has at least one sensor unit, in contact with the medium, for detecting measured values, and an operating unit with a display element, wherein the sensor unit is connected wirelessly or by wire to the operating unit for communication, wherein the method includes the steps of determining a first value that represents a remaining time span up to a specified time point for a maintenance measure to be performed on the sensor unit; determining a second value that represents a current state of the sensor unit; determining a third value, based at least upon the first and second values, that represents a recommended action with regard to the sensor unit; and displaying the third value or a symbol derived therefrom, or a signal derived from the third value, by means of the display element.

Abstract: A method for informing a process control center about the fact that a sensor is being disconnected from a measuring transducer that is arranged spatially remote from the process control center and electrically connected with the process control center. The sensor is connected with the measuring transducer via a plug-in connection. A method involving automatic transmission of a signal to the process control center when the plug-in connection is opened is designed in such a way that, when opening a bayonet joint that covers the plug-in connection, or when disconnecting the plug-in connection, in order to disconnect the sensor from the measuring transducer, an electric signal is generated in the plug-in connection or the bayonet joint, which is transmitted to the process control center.

Abstract: A transmitter and a method for mounting a transmitter on a panel, wherein the panel is a door or wall of an electrical cabinet, a display panel, a control panel or a diaphragm, wherein the transmitter includes a display module and a computer module, wherein the display module includes at least a first securement means and a cable, and the display module is connectable via the cable with the computer module. The method comprises the steps of: drilling at least a first hole in the panel, wherein the first hole is less than the area of the display module lying against the panel bringing the cable from a first side of the panel through the first hole to a second side of the panel securing the display module to the panel using a second securement means complementary to the first securement means securing the computer module to the second side, and connecting the computer module with the display module via the cable.
