German Dichtomatik sensor Dichtomatik model Dichtomatik price

Dichtomatik 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 are widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Distance sensors can be classified into optical distance sensors, infrared distance sensors, ultrasonic distance sensors, and others based on their working principles. Most distance sensors used in mobile phones are infrared distance sensors, which have an infrared emitting tube and an infrared receiving tube. When the infrared light emitted by the transmitting tube is received by the receiving tube, it indicates a short distance, requiring the screen to be turned off to prevent accidental operations. When the receiving tube does not receive the infrared light emitted by the transmitting tube, it indicates a long distance, and the screen does not need to be turned off. The working principles of other types of distance sensors are similar, judging distance by the emission and reception of a substance, such as ultrasonic waves or light pulses.

Dichtomatik sensor applications

The most widespread application of distance sensors is in mobile phones. Smartphones on the market all contain distance sensors. When a user makes or receives a call, the phone is close to the ear, which can easily lead to accidental operations (for example, cheeks puffing out when laughing may hang up the call). Therefore, a distance sensor is needed to monitor the distance in real time; when the distance is too close, it automatically turns off the screen to prevent accidental operations. In addition, distance sensors are also widely used for measuring mine shaft depth, detecting aircraft altitude, and exploring outdoor environments. With the continuous development of technology, they also show prominent performance in wearable devices (such as smart belts).

Dichtomatik sensor working principle

When time-of-flight laser sensors operate. Time-of-flight laser sensors must measure 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 transmission time 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 inexpensive time-of-flight laser sensors cleverly avoid this obstacle by using a simple statistical principle, namely the averaging law, to achieve a resolution of 1mm while ensuring response speed.

Dichtomatik sensor industry applications

1) Applied in taxi meter testing systems: To further save energy and reduce emissions and meet the metering 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: a host unit about the size of a password box placed on the back seat of the car, and a distance sensor attached to the car body. According to reports, 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 take 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 for solving long-distance measurement and inspection has been added—time-of-flight laser distance sensors. It provides application flexibility for various occasions, including the following: (1) Equipment positioning. (2) Measuring the level of material packages. (3) Measuring object distance and object height on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection occasions. (7) Aircraft ground clearance monitoring.
