ProSight Automation Radar Level Gauge Non Contact
ProSight Automation Radar Level Gauge for Liquid Solid Transmitter Non Contact 80GHz 4-20mARS485 HART is a non-contact radar level transmitter designed for continuous liquid level measurement in industrial tanks and vessels.
It is primarily used in water treatment, chemical processing, petroleum storage, food and beverage, pharmaceutical, and wastewater applications where accurate level monitoring is essential.
Featuring advanced 80GHz FMCW radar technology, ±1 mm measurement accuracy, multiple communication outputs, and a maintenance-free design, it provides dependable performance even in harsh operating environments.
Overview
ProSight Automation Radar Level Gauge for Liquid Solid Transmitter Non Contact 80GHz 4-20mARS485 HART is an advanced industrial level measurement instrument that utilizes high-frequency Frequency Modulated Continuous Wave (FMCW) radar technology to provide continuous, non-contact measurement of liquid levels. Unlike traditional contact sensors, the radar antenna never touches the process medium, making it ideal for corrosive liquids, chemicals, wastewater, oils, and other demanding applications.
Its narrow radar beam minimizes interference from tank walls, internal structures, agitators, and pipework while maintaining exceptional measurement accuracy. The instrument remains stable under varying temperatures, pressure, vapor, foam, and condensation, making it suitable for both simple and challenging process conditions.
Designed for modern industrial automation systems, the transmitter supports multiple output signals including 4-20mA, RS485, and optional HART, allowing seamless integration into PLC, DCS, SCADA, and remote monitoring systems.
How It Works
- Emits continuous 80GHz microwave radar signals toward the liquid surface.
- The radar signal reflects from the liquid surface back to the antenna.
- Internal FMCW signal processing accurately calculates the distance to the liquid surface.
- The transmitter converts this distance into a continuous level measurement.
- The measured level is transmitted through industrial communication outputs for monitoring and control.
- Since the measurement is non-contact, sensor performance is unaffected by contamination or product buildup on the liquid surface.
