In order to eliminate false alarm given due to medium with high viscosity sticking onto the probe , a special material acting as an insulation electrode have been added in between the active section and the grounding section.
As shown in the diagram, sensing probe always experience medium clogging on it and thereby produces a capacitance and resistance between the 3 parts. Since the electric field between the active section and the guard section is round shaped, there will be no current passing through the medium between the electrodes.
The Admittance level switch uses this principle, to add a guard section between the active section and the grounding section to block the admittance current to reach the vessel wall from the medium between the active section and grounded electrode. Although there would be a small amount of admittance current between the guard section and the active section, the circuit would not take this current value into account. Due to the guard section, only the admittance current change between the active section and the tank wall will be detected by the circuit, thus only when the sensing probe is in contact with the medium will there be a precise signal.

| The vibrating blade detector VEGASWING 60 became the standard for the anti-overflow applications on liquids. This solution offers maximum guarantees of safety because independent and not influenced by the same physical sizes as measurements of level. Concerned with safety units (valve, pump, warning signal, alarms,...) are directly connected downstream on a circuit separately which can be controlled regularly by simple support on a key test located on the off-set electronics of the detector. The threshold does not require any adjustment, it completely transparent because is given by the length of the sensor and the assembly. The principle is without wear and maintenance. Aggressive products are detected with reliability with materials with high chemical behavior like the hastelloy or enamel. These detectors offer a very broad applicatif spectrum because insensitive with the variations of dielectric, viscosity, pressure, temperature and foams. They in addition have a continuous self-monitoring which announces any defect instantaneously (rupture of line, failure of the blades, corrosion, short-circuit, etc.). Approvals ATEX II G for explosive zones are available and of the versions answering the classes of safety SIL 2 and SIL 3 according to standard IEC 61508 are deliverable. |

All of the capacitive level sensors are now available with automatic calibration should the overall length need to be changed.
The required length can be easily adjusted by the user. Once the length has been shortened the unit will require to be re-calibrated. This is now very simple, just requiring the "Zero Adjustment" button to be pressed with the tank empty and the "Maximum Value Adjustment" button to be pressed with the tank full. The calibration is then done automatically by the integrated micro controller.
The advantages of these level sensors includes the ease of adjustment, voltage or current outputs, extremly robust by virtue of the coaxial measuring principle and a 2" BSP head. Additional switching points are available optional. |
