ABSTRACT:
Disclosed is an arrangement for monitoring changes in an object's surrounding field, including a sensor-active region(s), a measurement path(s) with a driver for applying a variable, a receiver(s) detecting a variable, a circuit connected downstream of the receiver for determining changes in a surrounding field and generating a control and/or measurement signal, a further measurement path(s) or reference section(s) with a driver to detect changes in the variable and the measurement path(s), a clock circuit switched on at time intervals of the measurement path and the reference path a regulating device for the variable(s) introduced by the drivers in response to changes in the variable in the field, with the result that at the receiver average the same amplitude of the variable passes from the drivers and the sensor-active region to the receiver from the measurement paths the sensor-active region being coupled with high resistance to the drivers.
