Abstract: A sensor device (100), for measuring a surface (101), includes a lighting device (103) emitting a light beam (105); an optical device (107) splitting the light beam (105) into partial light beams (109, 111), and emitting the first partial light beam (109) toward a first surface area (113) and emitting the second partial light beam (111) toward a second surface area (115). A light sensor (117) is configured to receive a first surface area reflection (109-1) of the first partial light beam (109) and a second surface area reflection (111-1) of the second partial light beam (111). A processor (119) is configured to detect a distance of the first surface area (113) and of the second surface area (115) to the sensor device (100) based on a position of the first partial light beam reflection (109-1) and the second partial light beam reflection (111-1) on the light sensor (117).

Abstract: A multi-radiation identification and dosimetry system and method that allows for monitoring of alpha, beta, and gamma radiation is disclosed. The system/method incorporates a segmented silicon drift detector (SSDD) that allows measurement of directly absorbed radiation in the semiconductor (betas, conversion electrons, Lx lines, and alphas) on one SSDD segment and radiation from a radiation scintillation detector (RSD) on multiple segments of the SSDD. With the anode side of the SSDD directed toward the radiation inspection surface (RIS), the SSDD+RSD stacked radiation detector collects radiation which is processed by a charge sensitive amplifier (CSA) and then processed by a time stamping differentiator (TSD). A computing control device (CCD) may be configured to collect the time stamp differentiation data from the various SSDD segments to permit the simultaneous discrimination of several types of radiation by and presentation of these radiation types and counts on a display monitor.

Abstract: The invention relates to a valve cartridge for a solenoid valve, having a capsule, a magnetic armature that is movably guided within the capsule, a valve insert that is inserted into the capsule at a first end, and a valve body, which is pressed into a second end of the valve insert and has a main valve seat. The magnetic armature, moved by a generated magnetic force, moves a tappet guided within the valve insert. The tappet has a closing element with a sealing element which plunges into the main valve seat of the valve body in a sealing manner for carrying out a sealing function, and an associated solenoid valve. According to the invention the valve insert is configured as a one-part slotted bushing, and the valve body is configured as a bonnet-shaped bushing. The valve body configured as a bushing is pressed into a second end of the valve insert configured as a slotted bushing such that the main valve seat is disposed within the valve insert.

Abstract: The invention relates to a method and a device for producing a high-pressure-tight connection between a pole core and a valve sleeve of a solenoid valve and to an associated valve cartridge for a solenoid valve. According to the invention, the pole core is placed in a two-part compression mold, which comprises a middle die and an outer die, in such a way that a joining gap is produced between an inner bore of the outer die and the placed-in pole core. Subsequently, the pole core is placed against the valve sleeve and the valve sleeve is inserted into the joining gap. Then, the middle die and the outer die are pressed simultaneously with the pole core such that the valve sleeve passes into the joining gap. When a pressed diameter of the pole core is reached, the valve sleeve expands and is shaped in the joining gap between a first shaping edge and a second shaping edge and is joined onto the pole core. The diameter of the inner bore tapers between the first shaping edge and the second shaping edge.
