Germany LIEBISCH sensor LIEBISCH model LIEBISCH price

LIEBISCH sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and have been widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Proximity sensors can be divided into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, etc., based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which have an infrared emitting tube and an infrared receiving tube. When the infrared light emitted by the emitting tube is received by the receiving tube, it indicates that the distance is close, and the screen needs to be turned off to avoid accidental operation. When the receiving tube does not receive the infrared light emitted by the emitting tube, it indicates that the distance is far, and there is no need to turn off the screen. The working principles of other types of proximity sensors are similar, judging the distance by the emission and reception of a certain substance, such as ultrasonic waves or light pulses.

LIEBISCH sensor applications

The most widespread application of proximity sensors is in mobile phones. Smartphones on the market all contain proximity sensors. When a user answers a call, the phone is close to the ear, making accidental operations likely (such as hanging up the call due to a cheek pressing against the screen when laughing). Therefore, the proximity sensor monitors the distance in real time and automatically turns off the screen when the distance is too close to prevent accidental operations. In addition, proximity sensors are widely used for measuring mine shaft depth, detecting aircraft altitude, and exploring outdoor environments. With continuous technological development, they also show prominent performance in wearable devices (such as smart belts).

LIEBISCH sensor working principle

When time-of-flight laser sensors operate. Time-of-flight laser sensors must measure the transmission time extremely precisely because the speed of light is too fast. For example, the speed of light is approximately 3´108m/s. To achieve a resolution of 1mm, the electronic circuit of the time-of-flight ranging sensor must be able to distinguish the following extremely short time: 0.001m¸(3´108m/s)=3ps. Distinguishing a time of 3ps places excessive demands on electronic technology, making implementation too costly. However, today's affordable time-of-flight laser sensors cleverly avoid this obstacle by using a simple statistical principle, namely the averaging rule, to achieve a resolution of 1mm while ensuring response speed.

LIEBISCH sensor industry applications

1) Application in taxi meter testing systems: To further save energy and reduce emissions, and to meet the metrological needs of the electric vehicle industry, the mobile electric taxi meter testing system has been officially launched. The testing device is roughly divided into two parts: one is a host unit about the size of a password box, placed on the back seat of the car, and the other is a distance sensor attached to the car body. It is reported that the device uses the driving distance measurement method. As the driver drives a certain distance, the testing device and the meter sample synchronously. The entire testing process is expected to be completed in seven to eight minutes. 2) Wide range of applications in the automation field: Currently, in addition to ultrasonic sensors and standard photoelectric sensors, a new method capable of solving long-distance measurement and inspection tasks has been added—time-of-flight laser distance sensors. They provide application flexibility for various scenarios, including the following: (1) Equipment positioning. (2) Measuring the level of bulk materials. (3) Measuring object distance and height on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection scenarios. (7) Aircraft ground clearance monitoring.
