Explosion-Proof Fork Level Switch Manufacturer Recommendation: Jiwei Fork-11 Competing with VEGA
In industries such as chemical, pharmaceutical, food processing, grain storage, powder conveying, and new energy material production, monitoring the level of powders and fine granular materials is crucial for production efficiency, equipment safety, and on-site management. Particularly in explosive hazardous environments with flammable gases, dust, or high-temperature conditions, ordinary level measurement instruments often fail to meet the requirements for safety, stability, and sensitivity. Therefore, selecting a high-performance, highly reliable explosion-proof fork level switch has become an essential step for enterprises to enhance automation control and ensure safe production.
As a professional explosion-proof fork level switch manufacturer, Shenzhen Jiwei has independently developed the Fork-11 series, a high-performance product designed for measuring powder and fine granular material levels in explosive hazardous environments. This product excels in measurement sensitivity, explosion-proof rating, high-temperature resistance, anti-adhesion structure, intelligent diagnostics, and corrosion-resistant materials. Its technical specifications are comparable to international high-end brands like VEGA, providing stable, safe, and precise level monitoring solutions for hazardous applications.
1. Working Principle of Explosion-Proof Fork Level Switches
An explosion-proof fork level switch is a level detection instrument based on the vibration principle. The core component is the fork. When powered, the fork vibrates continuously at a specific frequency. When material comes into contact with the fork, the vibration frequency or amplitude changes. The internal electronics detect this change and output a switch signal, enabling high-level alarms, low-level alarms, silo overfill prevention, empty silo protection, or automatic control.
Compared with mechanical level devices, fork level switches have no complex transmission parts and are less affected by material impact, dust concentration, or media color. They are especially suitable for powders, fine granules, and low-density materials. The explosion-proof design is critical for safe operation in hazardous environments, making explosion-proof fork level switches widely applied in chemical powders, pharmaceutical raw materials, plastic granules, grain dust, lithium battery materials, mineral powders, and environmental treatment.
2. Core Advantages of Shenzhen Jiwei Fork-11 Explosion-Proof Fork Level Switch
2.1 Ultra-High Sensitivity, Minimum Measurable Density as Low as 0.008g/cm³
In powder measurement, lower material density requires higher instrument sensitivity. Traditional level instruments often fail to detect light powders, produce false alarms, or give unstable signals.
The Fork-11 series features a meticulously designed fork structure that significantly improves the response between the fork and the material, capable of detecting materials with a minimum density of 0.008g/cm³. It performs reliably for ultra-low density powders, fluffy materials, or highly flowable fine granules, maintaining stable and sensitive detection. Its performance matches high-end brands such as VEGA, providing a competitive solution from a Chinese manufacturer.
2.2 Anti-Adhesion Design for Powders and Fine Granules
Powders and fine granular materials often adhere, accumulate, or cake during production. Ordinary level switches may malfunction if material covers the fork surface, affecting continuous production.
The Fork-11 adopts an anti-adhesion design optimized for powders and fine granules, minimizing material buildup on the fork surface. It ensures long-term stable operation even in high-dust, high-humidity, or sticky material environments, reducing detection errors and maintenance frequency. This design enhances measurement reliability and reduces labor for on-site cleaning, making it ideal for continuous and unattended operations.
2.3 Extreme High-Temperature Resistance Up to 400℃
In chemical reactions, drying, sintering, heat treatment, and high-temperature powder conveying, level instruments must maintain stable detection and withstand harsh temperatures.
The Fork-11 series employs industry-leading high-temperature designs, working stably at up to 250℃ and capable of handling extreme 400℃ conditions. It ensures reliable monitoring for high-temperature storage bins, hot material silos, drying equipment, and reactors.
2.4 Dual Explosion Protection for Gas and Dust Hazardous Areas
In explosive hazardous environments, the instrument’s explosion protection directly affects personnel and system safety. The Fork-11 offers dual protection with intrinsic safety (IS) and flameproof design, suitable for complex gas and dust environments.
- Gas/Dust Flameproof: Ex db IIC T1…T6 Gb; Ex tb IIIC T80℃…T440℃ Db
- Gas/Dust Intrinsic Safety: Ex ia IIC T1…T6 Ga; Ex ia IIIC T200100℃…T200450℃ Da
This dual certification allows the Fork-11 to be used in chemical plants, pharmaceutical factories, dust workshops, grain processing, coal powder handling, and lithium battery material production, meeting stringent safety requirements.
2.5 Intelligent Fault Self-Diagnosis to Reduce Downtime
Unexpected instrument failure may cause silo overfill, empty silo operation, equipment blockage, or production interruption. The Fork-11 includes an intelligent self-diagnosis system, monitoring operation in real-time and quickly identifying abnormalities.
When fork anomalies, electronics malfunctions, signal errors, or potential failures occur, the system provides prompt feedback, helping personnel locate issues quickly and minimizing downtime. This feature improves reliability and control for continuous production enterprises.
2.6 Simplified Installation and Maintenance-Free Design
A top-quality fork level switch should be accurate, easy to install, and low-maintenance. The Fork-11 supports flexible installation for various silos, hoppers, tanks, and pipelines, suitable for top or side mounting.
Its maintenance-free design requires minimal intervention, significantly lowering operational costs. For high-dust, complex environments, or high/elevated installations, the Fork-11 reduces inspection frequency and improves overall efficiency.
2.7 316L Stainless Steel Material for Enhanced Corrosion Resistance
Corrosive environments shorten the life of level instruments. The Fork-11 uses high-quality 316L stainless steel, offering excellent corrosion resistance and mechanical strength, suitable for chemicals, food powders, pharmaceuticals, minerals, and other complex media.
316L steel improves durability against long-term vibration and material impact, extending service life. For industries requiring hygiene, corrosion resistance, and stability, the Fork-11 is a highly reliable choice.
2.8 Flexible Extension Cable Design Up to 20 Meters
For deep silos, large tanks, or special installation sites, standard short-rod level switches may be insufficient. The Fork-11 features a flexible cable extension up to 20 meters, adapting to deeper silos and complex environments.
Flexible cable design reduces external stress and mechanical impact, improving reliability and extending service life. It is particularly advantageous for large silos, powder storage, and deep-level detection applications.
