Technical details and application highlights

Review the complete description, feature set, and specification details before sending your inquiry.

The HR1200 60GHz millimeter wave radar level sensor is engineered for accurate and reliable liquid level measurement across demanding industrial environments. Using advanced high-frequency radar technology, it delivers precise, non-contact measurement unaffected by temperature, pressure, or vapor conditions. This makes it a dependable solution for industries requiring continuous monitoring and automation.

Key Features

The HR1200 sensor provides high-resolution measurement with ±2mm accuracy, ensuring consistent level detection in both static and dynamic conditions. Its narrow beam angle enhances targeting precision, reducing interference from tank walls or internal structures. With robust IP68 protection and wide temperature tolerance, it operates effectively in harsh industrial settings.

Application

This radar level sensor is widely used in oil storage tanks, wastewater treatment plants, chemical processing units, HVAC systems, food production tanks, marine vessels, and vehicle-based fluid monitoring systems. It is also suitable for process control environments where stable and maintenance-free measurement is critical.

Design & Functionality

Built with a compact and rugged housing, the HR1200 integrates seamlessly into industrial systems. The 60GHz frequency ensures strong signal penetration and stable readings even in challenging conditions like foam, vapor, or condensation. Its RS485 MODBUS RTU communication allows easy integration with PLC and SCADA systems for real-time monitoring.

Total Crossed Beams

The sensor utilizes focused radar transmission with minimal beam dispersion, ensuring accurate detection even in narrow or obstructed tanks. This improves measurement reliability in complex industrial installations.

Beam Pitch Options

With an optimized 8° beam angle, the HR1200 minimizes signal reflection from surrounding surfaces, enhancing accuracy in confined or irregularly shaped tanks.

Intrinsic Synchronism

The sensor maintains consistent signal synchronization, enabling stable readings even during fluctuating liquid levels or environmental changes.

Operational Advantages

The HR1200 offers non-contact measurement, eliminating wear and reducing maintenance costs. Its low power consumption supports energy-efficient operations, while its durability ensures long service life. This makes it a preferred choice for industries seeking reliable, automated level monitoring solutions.
