摘要： A flow sensor for flowing media with a cylindrical housing (2) and with a sensor element located in the housing (2), the housing (2) preferably having an outside thread (3) and being screwable into a union (4) of a pipe (5) or into an opening of a connecting piece (43). The flow sensor (1) has very high measurement accuracy while still being economically producible. There is a lifting body (6) which projects into the flowing medium, the lifting body (6) being movably guided on the housing (2) and depending on the flow (7) of the medium to be monitored, can be moved against the reset force of a reset element which is located between the housing (2) and the lifting body (6), and the sensor element is made as a noncontact proximity switch (18, 20) which produces a signal that is dependent on the position of the lifting body (6).

摘要： A heat transfer measurement device, in particular a flow monitor for the electrical measurement of heat losses in a flowing medium, with a metallic, circular cylindrical measurement device housing having an outside thread, with a first temperature measurement element, a heating element and a second temperature measurement element. The flow monitor in accordance with the invention is on the one hand quick in a thermal sense and can be manufactured relatively simply on the other. This is because the first temperature measurement element, the heating element and the second temperature measurement element are disposed on one side of a carrier foil which is a good electrical insulator as well as a good conductor of heat and in that the carrier foil is brought into thermally conductive contact with the measuring device housing with its side facing away from the temperature measurement elements and the heating element, at least in those areas where the temperature measuring elements and the heating element are disposed.

摘要： A contactless motion detector is energized in series with a load from a source of direct current via a pair of supply leads connected across a binary switching circuit in parallel with a voltage-generating network designed to deliver operating current to the detector in either switching position. The switching circuit comprises a main electronic switch, designed as a transistor, which is turned on or off by an output signal of the detector and in turn controls an ancillary electronic switch (transistor or thyristor) whose conduction intensifies the load current. When both electronic switches are transistors, they are interconnected in a positive-feedback loop driving them into conduction as soon as the main transistor is turned on; the base current of the ancillary transistor then contributes significantly to the load current while its collector current helps maintain the energization of the detector. The voltage-generating network includes a current limiter as well as a constant-voltage generator, e.g. a Zener diode.

摘要： A contactless motion detector, such as an oscillator sensitive to an approaching metallic element, is connected across a storage capacitor which can be charged from a source of pulsating direct current through a constant-current unit whose current flow is throttled when the charging voltage of the capacitor reaches a predetermined level. A thyristor connected across the series combination of storage capacitor and constant-current unit has a gate connected to a tap on a voltage divider lying in parallel with the capacitor so as to fire when the capacitor voltage rises substantially above the aforementioned level in order to break down a Zener diode forming part of that divider. Such a rise occurs when a transistor, inserted between the capacitor and a higher-voltage output of the constant-current unit, is turned on by a switching transistor responsive to a trigger signal from the detector. Untimely firing of the thyristor due to voltage fluctuations in the supply circuit can be prevented by an ancillary transistor, responsive to the same trigger signal, which normally either cuts off a protective transistor between the capacitor and the thyristor gate or establishes a shunt path in parallel with the voltage divider and the storage capacitor.

摘要： A contactless motion detector, such as an oscillator sensitive to an approaching metallic element, is connected across a storage capacitor charged from a source of pulsating direct current through a current-limiting device and shunted by a Zener diode. Connected across the series combination of storage capacitor and current-limiting device is an ancillary thyristor, triggerable by the detector, forming part of a firing circuit for a main thyristor in parallel therewith; that firing circuit further includes another Zener diode and a stabilizing resistor in series with the ancillary thyristor. Conduction of the main thyristor, upon the triggering of the ancillary thyristor, reduces to near-zero the resistance in series with a load, such as a relay, which is traversed by the current drawn from the source. With both thyristors cut off between pulsations of the source current, the storage capacitor is briefly recharged through a decoupling diode upon a retriggering of the ancillary thyristor before the firing of the main thyristor.
