Tube-11 Vibrating Rod Level Switch

Jiwei has been granted two invention patents on Tube-11 vibrating rod level switch (patent number: ZL 201510009538.3 and ZL 201510059187.7) and one utility patent (patent number: ZL 201620679133.0). One more invention patent is under checking and verification (application number: ZL 201610511184.7). 

●　High sensitivity thanks to the fine adjustment on the resonant vibrating frequency. It is suitable for the majority of granular bulk solids. The medium density can be as low as 0.02g/cm³;

●　An industry leading product that can tolerate high process temperature up to 250℃, and ultra-high temperature up to 400℃(Water/air cooling);

●　Excellent in the medium interface detection and control;

●　Larger redundancy to avoid medium buildup and highly reliable for the medium with higher viscosity and adhesiveness;

●　Strong self-diagnostic function makes it possible to accurately locate the fault.

●　Easy installation and no calibration necessary;

●　With CE certificates, gas/dust Flameproof Enclosure and gas/dust Intrinsic Safety certificates, and IP66/IP67 Ingress Protection.

●　Strong anti-corrosion probe thanks to the probe material selection, such as 316L and 318 S13.

●　The level switch for the silo with mixture of CaSO_₄and CaSO_₃ resulting from semi-dry desulfurizing reaction at a coal power plant.

　　● The problem of the medium buildup has been successfully solved due to a larger redundancy.

●　The fluctuation of the humidity results in an unstable dielectric constant of the mixture of CaSO_₄ and CaSO_₃. Our Tube-11 vibrating level switch could provide a reliable measurement in this situation because the measurement is independent of the dielectric constant.

●　Level switches for the soot bin inside the desulfurization equipment and the silo in the regeneration tower at a power plant.

　　● The temperature of the active coke is up to 180℃. Our Tube-11 can tolerate process temperature up to 250℃, and ultra-high temperature (Water/air cooling) up to 400℃.

●　The level switch for the environment friendly fuel tank in the combustion system at a power plant.

　　● The density of sawdust or straw is very low, only at 0.1g /cm³. It is out of measurable range for most of level switches in the market. However, Our Tube-11 successfully provided a reliable result in this situation. Tube-11 can work reliably for the medium density as low as 0.02g/cm³.

●　Level switches for the electrostatic precipitator bag, the ash hopper and the conveying pump in the ash transport system at a power plant.

　　● The probe is only 125mm long. It significantly reduces the impact area from the filling material and therefore prevent the probe from the possible impact damage.

●　The level switch for the coal bunker or powdery coal bunker in the ash collecting device in a coal power plant.

●　The level switch for the sintering ash silo at a smelting plant.

●　The level switch for monitoring the PVC granule storage silo, and the silo in the packaging line at a chemical plant.

●　The level switch for the hopper of a raw material bucket elevator at a cement plant.
