H760 series are positioned in the high-end intelligent product market and are widely used in the field of industrial automation, including chemical, oil and gas, food and beverage production, water and wastewater treatment, pharmaceutical, and environmental monitoring. They are suitable for various working environments, regardless of the type of liquid, the shape or material of the container, and can achieve millimeter-level measurement standards even under different temperature conditions.
Parameters
High-Performance Ultrasonic Technology: Provide a non-contact liquid-level measurement solution for industrial process control and monitoring.
Wide Range of Applications
Precision and Stability: High precision with a resolution of ≤3mm and are known for their stability in measurements.
Temperature Compensation: Built-in sound speed temperature compensation to ensure accuracy across different temperatures.
Versatile Communication Protocols: Support RS485 + Modbus RTU and capable of operating with sensors in the frequency range of 20KHz to 125KHz, with open channel users preferring sensors above 100KHz.
Sensor Disconnection Detection: Sensor disconnection detection, enhancing reliability and safety.
Customizable Display: 128×64 pixel LCD display, multiple variables including percentage, loop current, temperature, or distance.
Measurement Modes: Measure level, distance, or empty height, allowing for adjustment based on application requirements.
Robust Design: -20°C to 70°C (with LCD) and -40°C to 85°C (without LCD)
