Abstract: A measuring device for analyzing a lubricant of a bearing. The measuring device has an electromagnetic radiation emitter, a receiving element and a test area that is arranged between the emitter and the receiving element. The measuring device allows for current information on the condition of the lubricant in the bearing to be obtained. At least some sections of the test area are inside the bearing and the receiving element supplies a spectrum of electromagnetic radiation captured by the test area. Also, a bearing and a seal for the bearing and a method for detecting and monitoring the condition of the lubricant of a bearing.

Abstract: A sensor part for an infrared sensor, including an IR-sensitive detector (1), at least one reference source (2) emitting IR radiation, and an IR-sensitive reference detector (3) which, in the direction of the incident IR radiation, is at a distance from the detector (1), wherein the at least one reference source (2) is arranged at the side of the reference detector (3), and including a support (5), on the first side (6) of which the detector (1), the at least one reference source (2) and the reference detector (3) are arranged. The support (5) includes a blank made of a flexible material bent in some sections, in particular a blank made of a flexible printed circuit board bent in some sections. The invention achieves the aim of specifying a three-dimensional sensor part for an IR sensor that can be produced by a simple method. The invention further relates to a method for producing a sensor part and to an IR sensor.

Abstract: A device for detecting leaks in membranes, etc., for liquid media, whereby the membrane is provided, over at least one partial area of its surface extension, with at least one electrical conductor that produces a change in a measurement signal of the electrical resistance of the conductor when a change occurs on the membrane surface, the membrane being provided with a swellable nonwoven that joins or separates the conductors when influenced by the liquid.

Abstract: A method for measuring the pumping operating parameters of a diaphragm delivery unit, the conductivity of a resistance device mounted on a diaphragm being measured, at least over one pumping period, as a time-dependent quantity, and this quantity being used in the measurement.

Abstract: A device for monitoring the integrity of a diaphragm (1) of a diaphragm transport+ unit, made of one or a plurality of layers, having a resistance device (3) connected to one layer and having a measuring device interconnected to a current source (15) via a connecting arm (20), the measuring device being a Wheatstone bridge (2) in which the resistance device (3) forms a bridge resistance (S1, S2, S3, S4) in at least one bridge arm, and an incipient rupture of a layer of the diaphragm having the effect of altering the galvanometer arm voltage (B-D).
