摘要： A contactless motion detector responsive to the approach of a ferromagnetic element, including an oscillator with a sensing coil, has an output lead connected to one input of a first Exclusive-OR gate having another input connected to a square-wave generator whose pulses appear in the output of that gate with or without phase inversion depending on the output voltage of the motion detector. These pulses are fed, via an amplifier, to one input of a second Exclusive-OR gate whose other input receives the output pulses of the square-wave generator directly but with a delay compensating a lag introduced by the first gate and the amplifier. In the absence of a malfunction, the inputs of the second gate are energized either cophasally or antiphasally to produce either a low or a high output voltage of substantially constant magnitude fed to a load; in the event of a malfunction interrupting the pulse transmission to either input of this second gate, its output becomes a pulsating voltage. Such malfunction can further be indicated by an integrator connected in parallel with the second gate to the amplifier output. A conductor connecting the output of the square-wave generator to the corresponding input of the first gate is preferably led inside a housing around the motion detector, in front of its sensing coil, in order to let a damaging physical force aimed at the detector disrupt that conductor for giving rise to a malfunction indication.

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, 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, specifically an oscillator whose signal amplitude is attenuated or enhanced by the approach of a monitored metallic element, is periodically switched for brief periods into its alternate state by a train of short test pulses giving rise to corresponding checking pulses that are superimposed upon the integrated output voltage of the oscillator whereby that voltage is intermittently increased when at low level and/or intermittently reduced when at high level. These checking pulses, whether of the voltage-increasing or the voltage-reducing kind, are integrated to provide an enabling signal allowing a controlled load to be energized or de-energized according to the mean value of the output voltage; an absence of the enabling signal indicates a malfunction.

摘要： An electronic sensor of the contactless type has a free-running oscillator with internal positive feedback supplemented by an external negative feedback including a capacitive path whose impedance is normally high but is lowered in the presence of an object to be detected, thereby reducing the output signal of the oscillator from a normal amplitude above a predetermined level to a diminished amplitude below that level. The negative feedback is provided through an IGFET, e.g. of n-channel depletion type, with the aid of a capacitor bridging its source and gate electrodes to form with the external capacitance a voltage divider for the output signal of the oscillator.

摘要： A signal detector of a contactless proximity sensor feeds three voltage comparators with reference inputs connected to points of different threshold potentials. When the incoming signal exceeds only the lowest threshold, a light-emitting diode is flashed at a low frequency; when the intermediate threshold is surpassed, the diode flashes at a higher frequency, whereas its light emission is continuous in the presence of a signal level above the highest threshold. Only in the last two instances will a load-control circuit be switched.
