A device for transmitting measured values having a sensor module including miniaturized components and an evaluation unit, in which the sensor module has connections for different sensors, one or more sensors are connected to the sensor module, and the sensor detect operating states of a centrifugal pump arrangement including a pump and a drive motor as measured values. The sensor module is connected to a power supply and processes the measured values. Sensors that are connected to the sensor module are identified. The sensor module is constructed as a signal transmitter with a standardized output signal, an integrated evaluation unit, which has a microcomputer, and a display. The evaluation unit processes the measured values from the sensors and displays measured values and/or calculated variables on the display.
