摘要： The invention relates to an apparatus intended especially for making a contactless measurement of the thickness of measurement objects made of transparent material. In the course of this measurement, two opposing beams produced by a first and second radiation source are directed through first and second beam splitters and through a deflecting device consisting of a body of transparent material having reflecting and refracting boundary surfaces. Thereafter, the beams are directed obliquely onto the surface of the object to be measured. The first and second component beams are reflected off the forward and rearward surfaces, respectively, of the object and are directed through first and second beam splitters onto first and second detecting devices. In order to facilitate a compact configuration and higher measurement precision, the first and second beam splitters define the incidence surfaces of the deflecting device facing towards the radiation sources.

摘要： The cooktop has a cooking zone (2), at least one electric heating unit (7, 7′) assigned to the cooking zone (2) and a device for detecting a metal pot on the cooking zone (2) and determining its size when the metal pot is resting on the cooking zone (2). The device for detecting the presence and advantageously the size of the metal pot includes a measuring sensor (3) arranged near the cooking zone (2) and one or more evaluation devices (5, 5″) communicating with the measuring sensor (3). The measuring sensor (3) includes a primary measuring coil (8) and one or more secondary measuring coils. The primary measuring coil terminals (8a,8b) are electrically connected with corresponding poles of an alternating voltage generator (4) for generating an alternating current in the measuring coil (8) and a magnetic alternating testing field that interacts with the one or more secondary measuring coils to induce a voltage in them. The respective evaluation devices (5, 5″) include comparators (15,15″) for comparing the induced voltages in the corresponding secondary measuring coils (9,20) with voltage threshold values to detect the presence and advantageously the size of a metal pot placed on the cooking zone (2) as a result of eddy currents produced in the metal pot.
