GEMS RLI80 RADAR LEVEL SENSOR

Radar Level Sensor for Continuous, Non-Contact Tank Level Sensing Applications

PRODUCT LAUNCH: March 2022

• Compact Design – small footprint for flexibility in restricted spaces.
• Easy to Configure – simplified programming and setup via Bluetooth connection; run diagnostics to view signal strength and tank obstructions.
• Premium Housing Material – PVDF housing material grants high temperature resistance and chemical inertness to most medias.
• Pulsed Radar System – no contact required, no moving parts and reliable continuous sensing in the toughest applications.

Available in a compact design constructed from chemically inert PVDF material, the RLI-80 non-contact radar sensor works in tanks up to 15 meters (49.21 ft) deep! It’s simplified programming and setup via Bluetooth® connection makes installation quick and easy. In addition, it can run diagnostics to view signal strength and tank obstructions. Read below to learn more about Radar Technology and its benefits over other sensing technologies.

Features & Benefits:

• Non-contact design means no media ever encounters the Radar sensor. This eliminates the need to worry about material compatibility between the media and sensor components.
• The non-contact design is by default a no moving parts solution, which eliminates the potential for any mechanical failures from a float-based sensor.
• The non-contact design also eliminates the need to use large floats with long stems, decreasing shipping cost and shipping transit time. This also makes installation time a fraction of the time saving countless labor hours.
• Infinitely configurable to match any tank depth up to 15m eliminates the need to source multiple level transmitters, reducing inventory and sourcing costs.
• Also, since it never comes in contact with the media, there are no issues with debris coating or causing a float to get stuck.
• Radar through the air technology is a very accurate sensing technology and can detect liquid level within 5mm, with no effect on its accuracy based on changes in temperature or pressure.
• Radar technology is not affected by condensation or dust in the air like ultra-sonic based sensors.
