  • Field measuring device
    Patent number: 10784884
    Abstract: A field measuring device includes a sensor, a measuring transducer, and interface electronics. The interface electronics include a measuring and control device, and first and second terminals for connecting an external electrical device. A current controller and a current measuring device are connected in series in a terminal current path between the first and second terminals. The interface electronics has a voltage source that can be switched on in the terminal current path and disconnected from the terminal current path, so that the voltage source can drive a current in the terminal current path in the switched-on state and in the case of a connected external electrical device. The measuring and control device actuates and reads the current controller, the current measuring device, and the voltage source such that a current signal is output or input via the first and second terminals when an external device is connected.
