Vibrating Level Switch
Vibrating Level Switch is based on a cantilever beam vibrating principle. A cylindrical rod or a fork is used as a vibration probe. Piezoelectric devices are utilized to drive and detect the vibration. With state-of-the-art techniques, the specifications of our Vibrating Level Switch and its reliability reach to an advanced level in the field. When vibration probe comes in contact with medium, vibration amplitude and frequency of the probe will substantially decrease, so does the output of detecting piezoelectric device. The amount of decrease is analyzed by an intelligent circuit which outputs a switching signal as a result. Depending on the chemical and physical properties of medium, a series of Vibrating Level Switches can be chosen.
Jiwei has been granted 4 invention patents and 4 utility patents on Vibrating Level Switches so far.
Compared with similar products in the market, Jiwei Vibrating Level Switches have following advantages:
● Broader range of medium density, can be used for powder particles with extreme low density as 0.008g/cm³, and liquid density as low as 0.5g/cm³.
● Excellent adaptability, particularly suitable for a wide range of applications with unstable humidity and dielectric constant.
● Larger redundancy for medium buildup thanks to the precisely pre-adjusted resonance, highly reliable for the medium with higher viscosity and adhesiveness.
● High reliability because of higher quality chips purchasing, detail-oriented design, and strict production workflow and quality control.
● An industry-leading product for high process temperature applications, excellent performance under temperature up to 250℃, or ultra-high temperature up to 400℃ with water/air cooling.
● Smaller probe, particularly suitable for pipelines.
● Vibration probe is made of strong corrosion resistant materials, such as 316L.
● With SIL2/3 Qualification, CE certificates, CCC certificates, CCS certificate for ships (China Classification Society), gas/dust Flameproof Enclosure and gas/dust Intrinsic Safety certificates, and IP66/IP67 Ingress Protection.
● Strong self-diagnostic function makes it possible to accurately locate the faults.
Jiwei Vibrating Level Switch has four series of products to meet requirements of various applications:
Tube-11 Vibrating Rod Level Switch: This innovative Vibrating Rod Level Switch is designed with double vibrating rods, which is a first made-in-China model. It suits the majority level switch applications for granular and powdery bulk solids. The lowest medium density can be as low as 0.02g/cm³.
Fork-11 Tuning Fork Level switch: The area of fork body has been reasonably increased for higher sensitivity. Particularly suitable for powder and fine-granule with a density as low as 0.008g/cm³.
Ring-11 Liquid Level Switch: Qualified with SIL2 / SIL3 Certificates. With only 40mm length of the fork body, Ring-11 is a point level sensor to measure the liquid level in vessels, storage tanks, other process tanks, as well as bypass pipelines. The density of the liquid can be as low as 0.5 g/cm³.
Ring-21 Compact Liquid level switch: Ring-21 is compact, lightweight, easy to carry and economic. It is mainly designed for non-explosive applications. Suitable for pipelines or other applications with confined space.
