Overview

The difference between radio frequency admittance technology and traditional capacitance technology lies in the diversity of measurement parameters, the driving three terminal shielding technology, and the addition of two important circuits, which are improved based on valuable experience in practice. The above technology not only solves the problems of cable shielding and temperature drift, but also solves the problem of hanging materials at the root of vertically installed sensors. The two added circuits are a high-precision oscillator driver and an AC phase detector sampler.

Product Details

SIEMENS radar level gaugeFor a container made of highly conductive material, since the material is conductive, the grounding point can be considered to be on the surface of the probe insulation layer. For the transmitter probe, it only appears as a pure capacitor. As the container is discharged, material is hung on the probe rod, which has impedance. In this way, the previous pure capacitor has now become a complex impedance composed of capacitors and resistors.

Radio frequency admittance technology introduces measurement parameters other than capacitance, especially resistance parameters, which increases the signal-to-noise ratio of instrument measurement signals, greatly improving the resolution, accuracy, and reliability of instruments. The diversity of measurement parameters also effectively expands the reliable application fields of instruments.

The problem is that the material itself is equivalent to a capacitor to the probe, which does not consume the energy of the transmitter (pure capacitor does not consume energy). However, if the equivalent circuit of the hanging material to the probe contains a resistor, the impedance of the hanging material will consume energy, thereby pulling down the oscillator voltage and causing changes in the bridge output, resulting in measurement errors. We have added a driver between the oscillator and the bridge to replenish the consumed energy, thus stabilizing the oscillation voltage applied to the probe.

SIEMENS radar level gaugeDue to its good directionality, small emission angle, and strong resistance, the high-frequency radar level gauge is very suitable for measuring material levels in silos with large aspect ratios, especially in situations such as calcium carbide furnace and converter silos, where low-frequency radar cannot be used for measurement.

Compared with high-frequency radar, low-frequency radar has a much lower ability to combat dust due to its low frequency, dispersed energy, and insufficient energy concentration.

These reasons determine that high-frequency radar is the mainstream product for solid level measurement, and the difference between low-frequency radar level meters highlights the advantages of high-frequency radar level meters.
