Übersetzung für "Capacitance probe" in Deutsch

The WGA-AS capacitance probe is mounted above the constant level of the separator.

Changing with fill level is the capacitance of the probe PB.

Hence the capacitance of the probe changes.

The measuring device for determining the density of the medium is, for example, a gamma densitometer or a capacitance probe.

The WGA-ES4 capacitance probe is mounted at least 150 mm below the constant level of the separator.

Taking into consideration the parasitic capacitance of the probe, the line inductance can now be determined precisely.

However, the evaluation of the current amplitude by comparison with a fixed value is uncertain, as the value of the capacitive current depends on the inexactly defined capacitance to the probe.

Here, the electrical potential of the individual film sections 271 to 273 is dimensioned such that the resulting capacitance between probe core 10 and measuring winding 11 becomes minimal.

Such a design of the matching amplifier 13 is especially preferred because, here, the matching amplifier 13 can be provided with a high input resistance, which is, e. g., one hundred times greater than the internal resistance of the induction probe 10, and with a low input capacitance, which amounts approximately to only the 0.1 multiple of the probe capacitance.

Thus, thermal, mechanical or chemical influences may change the capacitance, that condensation deposits on the probe or the capacitance of the probe is increased due to an accumulation of filling material in the area of attachment, i.e., near the passage of the probe through the container wall.

Thus, the total capacitance of such measuring probes is composed of the probe capacitance, i.e., the capacitance along the actual measuring probe and the capacitance in the attachment area, i.e., near the passage through the container wall.

The advantage of this probe is the electronic with digital display, which shows the actual measured capacitance at the probe.

An electronic charging/discharging circuit 2 ensures charging and discharging, to be able to measure the effective capacitance between a probe, e.g., in the form of a pipette tip 3, and a grounded base plate 4 .

While both the measuring electrode and the supply connections of the amplifier are connected to the AC voltage source, it is possible to detect variations in the capacitance between the probe electrode and the target object.

From the current measurement via the corresponding measuring device 10, the total capacitance of the probe unit is ascertained and therefrom the fill level.

In the case of a capacitive sensor, a probe capacitance is measured, wherein the capacitance is dependent, inter alia, on the distance between the capacitor plates or the dielectric between the capacitor plates, i.e. on a material which is fitted between the capacitor plates, for example.

If no electrical connection has arisen through the medium, then the test signal is being applied essentially only to the capacitance of the probe unit (i.e.

For measuring the capacitance, the probe unit 5 is supplied by the electronics unit 7 with an actuating signal AS.

For the case, in which the medium 17 is non-conductive, no insulation is required, and the capacitance between probe electrode 14 and container 16 with the medium 17 as dielectric is measured.

For the case, in which the medium 17 has at least a low conductivity, additionally the capacitance between probe electrode 14 and medium 17 is measured, wherein the insulation 15 serves as dielectric of the capacitor formed of probe electrode 14 and medium 17 .

Reference 26 denotes a suitable capacitive probe.

The application was solved with a capacitive probe RFnivo 3300.

The capacitive measuring probe 12 is formed in the outlet valve 30 of FIG.

According to another possibility, the identifying data sensing probe may be formed as a capacitive probe for reading capacitive identifying data.

Capacitive measuring probes, hydrostatic pressure measurement converters, and flow measuring devices are all manufactured and distributed by the assignee of the present application.

The invention can, however, also be reduced to practice with the use of other probes, such as, for instance, capacitive probes.

If a vane anemometer is used, pulses are emitted as the vanes pass over a capacitive probe.

Precise moisture and temperature measurement in bulk solids – even in applications that capacitive probes do not master.

If possible, the capacitive probe should be mounted vertically or parallel to the counter electrode.

This device comprises a capacitive measuring probe 12, which is made up of two electrodes.

Floats, capacitive probes, or other sensors respond to the accumulation of gas and control the disposal of the gas fully or partly automatically.

However, on especially difficult products, it has been shown that the regulation of the feed is not always appropriate, because some of the product can stick to the capacitive probe and thus make fine adjustments difficult.

For evaluation of the actual frequency a capacitive probe 67 is connected through housing 52 via output 68 to the control stage 13', thus closing the control loop.
