Translation of "Vibration detector" in German

In the case of the field device, it is a vibration detector or a vibration limit switch.

The handy vibration detector weighs only 32 grams (including supplied battery).

By the integration, in accordance with the invention, of the microprocessor into the oscillation circuit, it is possible to influence a vibration detector in an ‘intelligent’ manner such that it exhibits a constant phase-frequency characteristic over an extended working range.

The safety chain 20 comprises, for example, a vibration detector, a manual (emergency) switch and a rotational speed relay.

Further, at least one sensor 20, e.g., a temperature sensor for monitoring the power tool temperature or ambient temperature, a pressure sensor for the fuel pressure, a pressure sensor for the atmospheric pressure, an acceleration sensor, a position sensor, a proximity sensor (e.g., for detecting the position of a fastener or tool), a Hall sensor (e.g., for measuring the speed of the setting piston), a humidity sensor, a vibration detector, a CCD receiver, or a microphone, is provided at the power tool 10 .

The data carrier according to claim 1, wherein a vibration detector is disposed on the data carrier.

It is set forth below in yet more detail which different oscillation modes occur for a vibration detector having, for example, paddle-shaped oscillating bars.

This minimizes the mechanical stress of the clamping, with the result that approximately no oscillation energy is transferred to the housing or to the fastening of the vibration detector.

Consequently, the fastening means of the vibration detector 1 are effectively prevented from being stimulated to execute resonant oscillations which could, in turn, interfere with the oscillations of the oscillable unit and falsify the measured data.

As soon as the BURGprotectTM vibration detector registers the vibrations an alarm signal of up to 100 decibels will sounds via the Smart Home Central Base 2200 siren.

The vibration detector Vibrancy 2020 recognizes these and triggers an alarm before potential thieves have even entered the property.

The base control unit, two contact detectorsfor window and door protection, a vibration detector for windowsand showcases and a handy remote control are included.

To guarantee reliable stable contacts against mechanical shock and vibration, the detector switches use a double-sided sliding-contact point structure.

It is also disadvantageous that there is no protection against reverse engineering in the case of known detectors comprising electronic components: A competitor can replicate a vibration detector with knowledge of the components without possessing detailed knowledge of the functional principle of the detector.

Analog measurement signals can hereby be detected from a test specimen using vibration detectors.

Known vibration detectors are distinguished by a closed oscillatory circuit constructed of analog components.

In contrast to known analog vibration detectors, the solution of the invention is implemented largely digitally.

If that isn't enough, there's microphones, electric eyes, pressure-sensitive mats, vibration detectors, tear gas, and even thermostats that detect the slightest rise in temperature.

The intrusion detectors are constructed as infrared detectors, ultrasonic detectors, microwave detectors, sonic detectors, vibration detectors, as well as capacitative detectors.

The invention relates to active intrusion detectors such as ultrasonic detectors, microwave detectors and capacitative detectors and passive to intrusion detectors such as infrared detectors, sonic detectors and vibration detectors.

The “in situ” determination of the actual, transferred vibrations by the detector 3 allows the secondary vibrations to be always changed on the basis of the transferred vibrations.

Apparatuses, so-called vibration detectors, are already known, which employ an oscillatable unit for detecting, respectively monitoring, the fill level of a medium in a container.

Consequently, at constant degree of covering, there is functional relationship between frequency change and the density of the medium, so that vibration detectors are well suited both for fill level and for density determination.

Vibration detectors of this kind are made and sold by the assignee under the mark ‘LIQUIPHANT’.

Vibration detectors in the form of fill level measuring devices make use of the effect that the oscillation frequency and oscillation amplitude depend on the particular amount of covering of the oscillatable unit: While the oscillatable unit executes its (resonance) oscillations in air free and undamped, it undergoes a frequency and amplitude change, thus a detuning, as soon as it becomes immersed, partially or completely, in the medium being measured.

A frequent metrological deviations during optical detection is incorrect positioning of the security marker relative to the detector, vibrations or different lighting conditions.

The control/evaluation unit comprises identical components for all embodiments of oscillatable units and for all areas of application of the vibration detectors.

Vibration detectors, or limit level switches, for detecting or monitoring fill level, phase boundary or density of a medium in a container are already known.

For example, TDR (time-domain reflectometry) detectors, vibration limit switches and sensors which operate in accordance with the capacitive measurement principle are known.

Therefore, with a constant degree of covering, a functional relationship with the density of the medium exists, so that vibration detectors are well suited both for fill level determination as well as for density determination.

The harvested grains that strike pulse detector 39 induce structure-borne acoustic vibrations in pulse detector 39, it being possible to determine—according to the present invention—the impact points of harvested grains 14 that strike pulse detector 39 via structure-borne acoustic vibrations 42 detected by pulse detector 39 and, based on these points of impact, to determine, across the working width of upper sieve 25, the separation of a sieve loss 33 that does not fall through upper sieve 25 .
