Radar sensors ensure proper material levels in hoppers for smooth production. When materials such as grains or concrete mixtures are loaded into the hopper, the air is filled with dry dust particles. Dust can cause signal loss in many optical sensors, and if dust accumulates on sensors, ultrasonic equipment may give incorrect readings. Radar waves, however, can penetrate airborne particles to accurately measure the material level in the hopper. People working at vending machines in restaurants, banks, or pharmacies need to react quickly to customers. KJT radar sensors can detect vehicles in snow, rain, fog, strong light, or low light conditions. In these environments, other sensor technologies may result in false detections or failures to detect vehicles. Through fast and efficient vehicle recognition, businesses can analyze traffic patterns, eliminate bottlenecks, minimize wait times, and ensure timely service.
The intense temperature fluctuations, fog, steam, and water mist within automatic car washes can make vehicle location detection difficult, even with commonly used ultrasonic sensors. Temperature changes affect the speed of ultrasonic waves, leading to inaccurate vehicle location information. Noise from the equipment and constantly changing airflow within the car wash can also interfere with ultrasonic sensors. However, a KJT radar sensor configured in retroreflective mode can reliably determine the vehicle's position, instructing the washing system to open and close the appropriate sections at the correct times. This saves water and detergent, improves washing efficiency, prevents equipment contact and damage to the vehicle, and ensures a high-quality wash.
There are over 100,000 commercial flights worldwide every day. These flights require a large number of ground support vehicles, such as belt loaders, passenger boarding stairs, and catering carts. This constant traffic on the tarmac greatly increases the likelihood of accidents and aircraft damage. New standards mandate that certain ground support vehicles be equipped with collision avoidance sensors. Unlike narrow-beam radar, radar sensors with wider beams, such as the KJT, use a 45-degree beam to detect aircraft being moved by tugboats or parked on the tarmac. These sensors continuously monitor the distance between the vehicle and the aircraft and send this information to the vehicle's controller. If the vehicle gets too close to the aircraft, the controller automatically reduces the vehicle's speed, lowering the chance of a collision and saving money and time.
In automotive assembly plants, new wheels are identified by sensors and picked up from the assembly line conveyor belt by robotic arms. Optical sensors struggle to accurately identify wheels because the shiny, curved surfaces of metal reflect light away from the sensor's receiver. KJT radar sensors, such as the KJT series, can identify these uneven surfaces, objects with glossy, reflective, matte black, or any other color, or objects with mirrors or windows. This allows KJT radar sensors to reliably detect the position of each wheel on the automotive plant's conveyor belt. The sensors then send this position information to the robotic arm's controller, allowing them to accurately determine their ready position. By detecting objects of any color, shape, or reflectivity on the assembly line, continuous production can be ensured, reducing downtime.
Large gantry cranes often move heavy loads close together in outdoor freight yards. Collisions can damage cargo, incur high crane repair costs, and lead to prolonged yard shutdowns and indefinite halts to freight transport. Long-range radar sensors using narrow-beam patterns can reliably detect obstacles and other cranes, preventing collisions while ignoring nearby cargo containers. Warehouse lifting equipment such as stacker cranes and forklifts can collide with and damage freight containers. These collisions result in lost time, cargo damage, and equipment damage. KJT sensors can be used for short-range collision avoidance. When installed on lifting equipment, these sensors can detect freight containers and signal the equipment, causing it to automatically slow down and approach at a safe speed. Because radar is unaffected by changes in environmental conditions, radar sensors can even be used to monitor equipment operating both indoors and outdoors, such as vehicles moving goods from indoor loading areas to waiting areas outdoors. Using the same sensors on all equipment also minimizes maintenance costs.
Some radar sensors operate at low frequencies, such as emitting radio waves at 24 GHz. Others use higher frequencies, such as the KJT30R which operates at 122 GHz. Still others, like the K50R, operate at a moderate frequency of 60 GHz. Whether low-frequency, high-frequency, or in between, each frequency has its advantages. The 24 GHz low-frequency sensor is best suited for detecting large objects due to its longer wavelength. It offers long-range detection and is unaffected by heavy rain or snow, making it the most effective outdoor detection solution. Conversely, the 122 GHz high-frequency sensor produces short waves, excelling in detecting small objects with high accuracy and capable of detecting a wider range of dielectric materials. Radar sensors operating at 60 GHz have capabilities comparable to higher-frequency sensors, detecting various materials both indoors and outdoors. They can also ignore precipitation, just like low-frequency radar sensors.
As electric vehicles (EVs) become increasingly common, EV charging stations in public places will also become more prevalent. These charging stations not only need to be resistant to vandalism, but also to prevent non-EVs from parking in front of them and obstructing their use. This necessitates a system that reliably identifies unauthorized vehicles while concealing and protecting them from damage. Radar sensors like KJT are ideal for EV charging stations, functioning even when housed in plastic enclosures. KJTs can detect the presence of vehicles when parked at the station, regardless of weather conditions. If a vehicle is detected but not plugged into the charging station, a signal is sent to a central location to alert relevant personnel to the violation or improper use of the parking space. The offending vehicle is then removed, ensuring EVs can use the charging station.
Monitoring material levels in storage tanks typically requires sensors installed inside the tank. However, sometimes external sensor solutions are necessary, especially when direct contact with the liquid could damage or adversely affect the sensor. Radar sensors, capable of penetrating most plastics and glass, can be installed outside the tank for easy installation and maintenance.
KJT radar sensors can be installed on the outer wall of plastic storage tanks or on the inspection window of metal tanks. The inspection window or tank may be dusty or dirty, the plastic may be opaque, or the material inside the tank may be shrouded in mist. Even with uneven liquid levels or under pressure or vacuum conditions, high-frequency radio waves can penetrate plastic or glass to measure the liquid level. When connected to an illuminated indicator system, operators can visually assess the tank level without the need for an external controller.
To identify vehicles entering the auto repair shop, KJT radar sensors can be mounted under heavy-duty plastic, flush with the driver's side surface. Radar waves can penetrate dust and water left on the repair area floor and detect vehicles as they park. These sensors in the indication system can notify employees of a customer's arrival, allowing for a quicker greeting, minimizing wait times, and improving registration efficiency.
In some situations, sensors monitoring large areas must identify only certain objects while ignoring others, such as background objects or small objects near the sensor. The horizontally mounted KJT wide-beam sensor can detect trucks approaching a loading dock. By instructing the sensor to identify the nearest target, it detects the truck parts closest to the dock, rather than axles or truck body that might return a stronger signal. A strip of illumination connected to the sensor provides real-time feedback to the driver so they know exactly how close the truck is to the dock. Using KJT's radar configuration software, the T30R's detection range can be set so the sensor only observes within a predetermined range. Vehicles traveling in the background, pillars near the dock, and other unwanted objects, near or far, are all ignored.
Busy railway yards present a large-scale, dynamic working environment where multiple operations occur simultaneously. Vehicles and railcars of varying shapes and sizes move at different speeds along multiple tracks and around the yard, carrying various types of materials, posing a significant challenge to object detection. Trains consist of locomotives and a wide variety of railway vehicles, including box cars, flatcars, hopper cars, tank cars, and more. Radar sensors like KJT can track the types of goods on numerous trains and trailers at varying distances, even when they are in motion. Because it can detect both moving and stationary targets, KJT radar is a more reliable solution than Doppler radar, which can only detect moving targets. Even in dusty yards or with dust accumulating on KJT sensors, the radar signal can still detect objects up to 40 meters away. The radar sensor can be configured to ignore trains stopped in the track background but identify them when other trains pass by, triggering the RFID antenna, allowing operators to know the exact location of goods in the yard. The long-range detection capabilities offered by radar sensors, coupled with their ability to "ignore" surrounding weather conditions and airborne dust, make them an ideal solution for railway freight yards.
Sharp edges and flat surfaces installed at an angle can deflect radar signals like a mirror, making it difficult for radar systems to receive accurate information. To ensure reliable object detection, wide-wave radar sensors can be used to monitor large areas and continuously identify circular surfaces and tilted objects. Busy open-pit mines contain equipment of varying shapes and sizes, both mobile and stationary. Huge haul trucks transport both minerals and waste, and their massive bodies create numerous blind spots around the vehicles. With little room for error, collision avoidance becomes crucial for efficient operation. The outdoor environment also presents other detection challenges, including wind, rain, snow, and dust generated by mining operations. Wide-angle radar sensors such as KJT can be deployed at the front and rear of haul trucks as a key component of collision avoidance systems. They not only ignore surrounding weather conditions but can also be configured to detect objects in blind spots, regardless of the object's shape, size, color, material, or surface finish. By connecting KJT radars to LED indicator lights, truck operators can quickly identify when to check blind spots and slow or stop the equipment, reducing costly potential collisions.
