Radar level transmitter MRL-3300

Marmonix MRL-3300 Non-Contact High-Frequency Radar Level Transmitter

The Marmonix MRL-3300 is an industrial-grade, non-contact radar level transmitter engineered with a high-frequency 26 GHz radar sensor and advanced microprocessor signal processing. Specifically designed for high-dust, aggressive solid material environments, the MRL-3300 delivers stable continuous level monitoring up to 30 meters with an accuracy of ±15 mm.

In heavy industrial process environments—such as cement silos, grain storage bins, mining aggregate hoppers, and chemical solid reactors—suspended dust and angled surface reflections severely disrupt conventional ultrasonic sensors. The Marmonix MRL-3300 emits a narrow 26 GHz microwave beam that penetrates heavy atmospheric dust, high ambient vapor, and fluctuating media surfaces, ensuring continuous and maintenance-free inventory tracking without probe wear or product contamination.

Key Features & Operational Advantages

• Non-Contact Measurement: Horn antenna configuration (SS304) avoids mechanical wear, product coating, and corrosive buildup.
• High Dust & Vapor Immunity: Shorter 26 GHz wavelength guarantees optimal beam reflection from uneven solid angles and turbulent media.
• Narrow Beam Angle: Concentrated microwave energy minimizes false vessel-wall reflections and internal obstruction echoes.
• Hazardous Area Certified: Built to Exia IIC T6 Ga intrinsically safe standards (with optional flameproof Exd(ia) IIC T6 Ga casing).
• Versatile Output & Telemetry: Supports 4–20 mA (2-wire/4-wire), HART protocol, and RS485/Modbus integration into DCS/SCADA networks.
• Rugged Enclosure: IP67 die-cast aluminum housing (optional SS304L) with process temperature handling from -40°C to +250°C (Kalrez seal).
