Gaga Radar Level Sensor

Gaga Radar Sensors use millimeter waves, which refer to radar waves with extremely short wavelength ranges. Gaga has been producing non-contact level sensors using millimeter waves since 2009. Currently, Gaga Radar Sensors are used for a variety of applications, including silo level measurement, molten metal level measurement, collision prevention, hot metal detection, conveyor belt speed measurement, vehicle speed measurement, etc.

Gaga Radar Sensors are impervious to environmental factors such as snow, rain, fog, and clouds, and are capable of penetrating thick dust or vapors. Installing a GAGA Radar Sensor in a location that was difficult to acquire accurate readings with existing level or distance sensors can help operators manage nearby equipment.

Special Particulate Level Sensor :

Measuring the particulate level with a 26GHZ radar sensor inside a silo with extremely high particle levels may lead to a hunting phenomenon.

However, GAGA’s radar uses millimeter waves with short wavelengths. This improves its ability to penetrate through highly contaminated air and boosts its ability to measure the particulate level inside silos with extremely high dust or vapor levels.

Super-High Temperature Molten Metal :

This product uses millimeter waves with excellent penetrating capabilities, making them perfect for measuring targets with super-high temperatures. When a sensor is inserted into a tank or container to measure its internal environment, the microprocessor will malfunction due to the extreme temperature or pressure levels inside the tank or container.

GAGA sensors use ceramic flanges, etc. fitted to a hole at the top of a container. This prevents its waves from diffusing, which would happen if you use gamma-rays or x-rays from the outside of a container, and makes sure nothing can interfere with the measurement results from inside the container.
Moreover, GAGA sensors maintain their detection capacity even when the container has high levels of particulates or open flames inside.

They also retain a stable TOF gain and linearization in cases where the container holds lava-like molten iron or molten glass, molten zinc, or molten magnesium, which means the sensors can perform their measuring functions without being affected by the medium inside the container.
Not only that, GAGA sensors do not display any spot diffusion effects that typically appear in ultrasonic waves or other radar waves of 6GHZ, and 26GHZ. Instead, they can emit a source to the target much like a laser.

• Level measurement in extraordinary environments (super-high temperature silo levels, shaft furnace levels)
• Continuous casting mold level measurement, Torpedo ladle car level measurement, Molten metal level measurement
• Measured outside the tank, therefore no damage due to extreme temperatures

Hot Metal Detector :

GAGA HMD/CMD products use millimeter waves instead of detecting light in the infrared spectrum. As such, they remain accurate (no errors) under conditions with extremely high particulate levels, which is typical during steel production processes.

Millimeter waves also have outstanding penetration capabilities impervious to vapors. GAGA HMD/CMD products are easy to maintain - they do not require cleaning even when dust covers the lens. Not only that, their sensors work when the lens is completely covered with fabric as well.

Belt Speed Detector :

Belt Speed Detectors measure the speed of conveyor belts used to transport materials such as ores, cokes, etc. without requiring contact (non-contact measurement), and they notify the operator when any anomalies are detected.

Specifically, they can warn the operator of any belt slippage or stoppage to prevent accidents. Existing rotary contact-type belt speed detector sensors require contact with the belt, which wears down the belt over time.

Moreover, axles can deteriorate and bearings can become rigid. All of these are typical shortcomings of contact-type detectors that will require operators to replace parts regularly.

• Belt Conveyors

Crane Anti-Collision Sensor :

GAGA Crane Anti-collision Sensors use millimeter waves instead of detecting light in the infrared spectrum. As such, they remain accurate (no errors) under conditions with extremely high particulate levels, which is typical during steel production processes. Millimeter waves also have outstanding penetration capabilities impervious to vapors. GAGA Crane Anti-collision Sensors are easy to maintain - they do not require cleaning even when dust covers the lens.

GAGA Crane Anti-collision Sensors use millimeter waves with excellent penetrating capabilities, making them perfect for preventing crane collisions.

3D Radar Sensor :

All radar sensors currently used for level-measuring purposes in the field are capable of measuring a single point only. As such, when a bridge occurs inside a silo, it is extremely difficult to get an accurate and precise level reading. GAGA 3D Radar Sensors, however, acquire up to 36 Polygon Data points to measure the level inside a container. This means that it can provide accurate level measurements even if the surface of the medium inside is not smooth.

GAGA 3D Radar Sensors are also impervious to dust, open flames, or vapors, making them the perfect solution when measuring powder silos with high particulate levels. Since GAGA 3D Radar Sensors use millimeter waves with extremely short wavelengths, and the sensors are easy to maintain - they do not require cleaning even when dust covers the lens.
