German BST sensor BST model BST price

BST sensors are a general term for sensors designed to detect objects without physical contact, replacing contact-based detection methods such as limit switches. They convert information about an object's movement and presence into electrical signals. Detection methods that convert data into electrical signals include those utilizing eddy currents generated in the metal body of the detected object due to electromagnetic induction, methods detecting capacitance changes in the electrical signal caused by the approach of the detected object, and methods using reed and guide switches.

BST sensor applications

The most widespread application of distance sensors is in mobile phones. Smartphones on the market all contain distance sensors. When a user answers a call, the phone is close to the ear, making accidental operations likely (for example, cheeks puffing out during laughter may easily hang up the call). Therefore, distance sensors are required to monitor the distance in real time, automatically turning off the screen when the distance is too close to prevent accidental operations. In addition, distance 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).

BST sensor working principle

When a time-of-flight laser sensor is in operation, it must measure the transmission time with extreme precision because the speed of light is very high. 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 resolve the following extremely short time interval: 0.001m¸(3´108m/s)=3ps. Resolving a time interval of 3ps places excessive demands on electronic technology, making implementation prohibitively expensive. However, today's affordable time-of-flight laser sensors cleverly avoid this obstacle by utilizing a simple statistical principle, namely the law of averages, to achieve a resolution of 1mm while ensuring response speed.

BST sensor industry applications

1) Application in taxi meter testing systems: To further promote energy conservation and emission reduction, and to address 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: a main unit similar in size to a password case, placed on the rear 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 the car for 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) Extensive use in the automation field: Nowadays, in addition to ultrasonic sensors and standard photoelectric sensors, automatic detection and control methods have added a new solution for long-distance measurement and inspection—the time-of-flight laser distance sensor. It provides application flexibility for various occasions, including the following: (1) Equipment positioning. (2) Measuring the material level in bins. (3) Measuring the distance and height of objects on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection scenarios. (7) Aircraft ground clearance monitoring.
