A sensor apparatus for detecting a target object influenced by a process or formed in the process includes a sensor unit and an evaluation device. The sensor unit detects the target object in a detection zone of the sensor unit and generates a sensor signal that can be influenced by the target object. The evaluation device processes the sensor signal as a first input variable and generates an output signal, which indicates the detection of the target object, in dependence on the sensor signal. The evaluation device further processes a process parameter of the process, which acts on the target object, or a target object parameter, which characterizes the target object and is influenced by the process, as a respective further input variable and to generate the output signal in dependence on the process parameter and/or the target object parameter.

Sensor apparatus

A contrast sensor for evaluating identification markings and a method of evaluating identification markings on detecting objects using a contrast sensor, having at least one light transmitter and at least one light receiver, with the light receiver having a single photodiode; having a control and evaluation unit for evaluating the light receiver signal of the light receiver, and having an output for a sensor signal that is formed by the control and evaluation unit on the basis of the light receiver signal, wherein the identification marking has lettering or a marking; an elongate illumination field is projected by the light transmitter onto a region of the identification marking narrow in the direction of movement; and the control and evaluation unit compares a reception signal sequence having a plurality of contrast transitions with a stored reception signal sequence and outputs the sensor signal in dependence on the comparison.

Contrast sensor

The invention relates to a sensor for determining a filling level of a liquid fellable into a container, having a light transmitter for transmitting at least one light pulse; having a receiver for receiving at least one reflected back light pulse, wherein the light pulse is at least partly reflect able at a liquid surface; having a control and evaluation unit for controlling the sensor and for evaluating the received back light pulse; and having a coupling and decoupling unit for coupling the light pulse into a liquid jet which can be introduced into the container and for decoupling the back light pulse to the receiver, wherein the control and evaluation unit is configured for determining a time difference between a transmission of the light pulse and a reception of the back light pulse to calculate a distance between the coupling and decoupling unit and the liquid surface.

Sensor for determining a filling level

An optoelectronic sensor () is provided with a plurality of light transmitters () and light receivers () that form between one another a field () of mutually parallel monitoring beams (), wherein beam shaping optics () are assigned to the light transmitters () and the light receivers (). The optics () comprise a geometry and arrangement leading to a mutual overlap of the optics () in a direction diagonal, in particular perpendicular, to the field ().
