Ultrasonic Sensor: Industrial Insight Breaking Through Detection Boundaries, Analysis of Three Series of Precise Solutions

In the field of industrial automation, the innovation of detection technology has always been the key to improving production efficiency and accuracy. When traditional sensors face detection bottlenecks such as color, material, and reflection, ultrasonic sensors, with their unique technological advantages, have become versatile players across multiple scenarios such as liquid level, material level, and target detection. Today, we will delve into the three major series of ultrasonic sensors from Kronz U12, U18, and U30, and see how they break through the boundaries of industrial testing with "sound" as their focus.

1、 Ultrasonic sensors: versatile players in industrial testing

1.Ultrasonic sensors can detect almost all liquids, such as purified water, oil, and various solvents.

2. Ultrasonic sensors detect different colors of ink, ink, etc.

3. Testing various transparent materials, such as glass bottles, glass plates, transparent PP/PE/PET films, etc.

4. Ultrasonic sensors for reflective materials can perform well, such as detecting gold foil, silver foil, etc.

Almost all fiber fabrics of different colors can be easily detected by ultrasonic sensors.

6. Ultrasonic sensors are also very suitable for automatic control of powder particle levels such as grain, coal, sawdust, cement, etc.

2、 Three core series: precise matching of different industrial scene requirements

(1) U12 series: short distance high-precision detection expert

Size advantage: M12 external thread design, with a minimum external size of only 57mm, suitable for small spaces

Detection capability: 120/200mm range, narrow cone focusing on small targets

Function highlights: three mode output (switching value/analog value/RS485), white line distance learning, temperature compensation

（2） U18 series: cost-effective choice for 1-meter range

Flexible installation: M18 external thread, 45/55mm shell+elbow model

Range coverage: 0-1 meter universal detection, balancing volume and cost

Intelligent configuration: gray line distance learning, temperature compensation, external synchronization function

（3） U30 Series: King of Large Range Anti Interference

Strong detection: 2000/4000/6000mm wide range, suitable for large scenarios

Environmental adaptation: anti dust, anti vibration design, stable operation under harsh working conditions

All round configuration: three mode output, grey line learning, temperature compensation, external synchronization

3、Full scenario application: Deep penetration from industrial production lines to intelligent devices

(1) Liquid level and material level detection: visualizing "invisible" materials

In the powder granule packaging machine, the U30 series monitors the particle level inside the tank in real-time, calculates the material height accurately through sound wave reflection, and provides real-time data support for the automatic feeding system to avoid production line downtime caused by material shortage.

In the drainage system of subway stations, the U30 series serves as a "water level sentinel", monitoring the water level in the pit 24 hours a day and issuing timely warnings when the water level reaches the warning value to ensure the safety of subway operations. This non-contact detection method not only avoids the wear problem of traditional contact sensors, but also can work stably in harsh environments such as corrosive liquids.

(2) Target detection: the "tactile nerve" of industrial robots

In the robot grasping system, the U18 series is installed in the machine system to provide accurate grasping feedback for the robot by detecting whether the target object is grasped.

When the car rain line is running, the U30 series takes on the task of vehicle inspection. Whether it is a sedan, SUV, or truck, regardless of the color or material of the body, it can accurately identify the vehicle's position, control the start and stop of the rain system, and ensure that each vehicle can undergo uniform rain testing. This detection feature, which is not affected by the appearance of objects, greatly enhances the compatibility and reliability of automated production lines.

（3） Obstacle detection: the "safety protection net" of industrial equipment

In the field of port machinery, the U30 series' remote detection capability builds collision barriers for large equipment such as gantry cranes, providing early warning of obstacle distances and preventing collision accidents.

Rail cars and inspection robots prefer the flexible and compact U18 series, which can achieve close range collision detection and avoid dangerous situations such as robot falling off stairs through anti fall detection function. From large construction machinery to small mobile devices, ultrasonic sensors are combined in different series to ensure industrial safety.

（4） Roll diameter detection and tension control: the "precision guardian" of precision machining

In the cutting and stacking integrated machine, the U18 ultrasonic sensor is installed vertically with the winding surface. By calculating the time difference between the emission and reception of ultrasonic waves, the distance between the sensor and the winding surface is fed back in real time, thereby accurately monitoring the diameter of the pole block winding and providing key data support for precision processes such as lithium battery pole piece processing.

In the application of leveling machines, the U30 series detects the sag of steel plates and provides real-time parameters for the tension control system, ensuring that the steel plates achieve ideal flatness during the leveling process and improving the quality of metal processing.

Conclusion

From micro part detection to large-scale equipment monitoring, from single function sensors to full scene solutions, whether pursuing high-precision electronic manufacturing or heavy industry requiring a large number of processes, there is always an ultrasonic sensor that can become the "industrial eye" for upgrading your production line. Now, let's use "sound" as a guide to usher in a new era of precision in industrial testing. Feel free to leave a message to discuss your specific testing needs and obtain customized solutions.
