JM3020-10G1DS1P300 Level Switch Product Introduction (English Version)
The JM3020-10G1DS1P300 level switch is an intelligent material detection device designed for industrial process monitoring, suitable for level control applications involving solid particles, powders, and liquid media. Utilizing Radio Frequency Admittance (RF Admittance) measurement principle with advanced signal processing algorithms, it effectively distinguishes actual material signals from coating interference, ensuring precise and reliable detection performance.
Constructed with 316L stainless steel housing through integral casting technology, the device features multi-layer protection for internal electronic components. It maintains stable operation within temperature ranges from -40℃ to +150℃ and withstands pressure up to 4.0MPa. The probe is equipped with wear-resistant ceramic coating, particularly suitable for detecting abrasive granular materials. The dual-chamber isolation structure completely separates signal processing units from field environments, significantly enhancing long-term operational stability in humid and dusty conditions.
Functionally, this model supports both PNP/NPN signal outputs compatible with mainstream control systems including PLC and DCS. The built-in temperature compensation module automatically corrects measurement deviations caused by ambient temperature changes. Three-color LED indicators provide visual status monitoring. Modular design facilitates quick field installation and maintenance, with multiple threaded connection options (G1", G1½", G1¾") available for different installation requirements.
Typical applications include material monitoring in cement production, grain processing, petrochemical plants, and metallurgical operations. It performs high/low level interlock control in fly ash silos, precise feeding system management in corn starch production lines, and safety alerts for lubricant tank levels. Corrosion-resistant characteristics make it suitable for liquid level monitoring in acid/alkali solution storage tanks, while explosion-proof versions meet hazardous area requirements.
