摘要： 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.

摘要： The invention relates to a sensor for determining a filling level of a liquid fillable 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 reflectable 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.

摘要： A method of measuring objects that are conveyed in a conveying direction comprises the steps that
(i) a first object edge of a conveyed object is detected at a first measurement position by means of a first optoelectronic sensor,
(ii) the first object edge or a second object edge of the object is detected at a second measurement position, which is spaced apart from the first measurement position in the conveying direction, by means of a second optoelectronic sensor that is spatially resolving at least in the conveying direction,
(iii) a time difference between the detection of the first object edge at the first measurement position and the detection of the object edge detected in step (ii) at the second measurement position is determined,
(iv) a transit time is determined in which the object edge detected in step (ii) moves through a predetermined measurement path,
(v) the object speed is determined based on the transit time and a length of the measurement path, and
(vi) the length of the object is determined based on the determined time difference and the determined object speed.-

摘要： 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.
