What makes the 80GHz FMCW radar better than lower-frequency radar?

The 80GHz frequency produces a narrower beam angle (about 8°), enabling better focusing in narrow tanks and avoiding false echoes from agitators or internal structures. It achieves ±2mm accuracy up to 80m range.

Is the AM-RL80 certified for hazardous areas?

Yes, it carries ATEX and IECEx Ex d IIC T6 explosion-proof certification, making it suitable for hazardous area installations including oil and gas, chemical, and LPG/LNG applications.

What is the maximum process temperature?

The AM-RL80 operates from -40°C to +200°C process temperature with IP67 protection.

Does it require contact with the measured medium?

No, the AM-RL80 is a non-contact radar level transmitter. It mounts on top of the tank and measures through air, making it ideal for corrosive, abrasive, or high-temperature media.

What output protocols are supported?

4-20mA HART and RS485 Modbus RTU are standard, powered by 12-36V DC.

How to Choose

What to look for

•Accuracy: Match your process tolerance. 0.25% FS for custody transfer, 1% FS for tank level monitoring.
•Range: Ensure the sensor covers your full tank depth, including dead zones. Add 20% margin.
•Medium compatibility: Check wetted material against your fluid's chemical compatibility chart.
•Output signal: Match your PLC/DCS interface. 4-20mA is universal; RS485 for Modbus; EtherNet/IP for industrial Ethernet.

Installation & Wiring

•Power: Most AccuMeasure instruments run on 12–36V DC. Battery-powered models available for remote sites.
•Mounting: Threaded (G1/4, G1/2, M20), flange (DN25–DN200), or clamp-on. Standard process connections ship with the unit.
•Wiring: 2-wire (loop-powered) or 4-wire configurations. All units include a wiring diagram on the housing label.
•Environment: Check IP rating for outdoor installations. IP67 units are suitable for direct rain and dust exposure.

Not sure which configuration is right for you? Ask our engineers — we'll review your spec and recommend the best option.

Quality & Certification

72-Hour Aging Test

Every unit runs continuously for 72 hours under temperature cycling (0°C to 50°C) to detect infant mortality failures before shipment.

Calibration Certificate

Individual calibration certificate with traceable reference standards included with every shipment at no extra charge.
