German TRAFAG sensors sensor TRAFAG sensors model TRAFAG sensors price

TRAFAG sensors sensors are sensors that use laser technology for measurement. They consist of a laser emitter, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument; their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference.

TRAFAG sensors 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 it easy for accidental operations to occur (for example, cheeks puffing out while laughing may easily hang up the call). Therefore, distance sensors are needed to monitor the distance in real time. When the distance is too close, the screen is automatically turned off 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).

TRAFAG sensors sensor working principle

When a time-of-flight laser sensor is in operation. 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 transmission time ranging sensor must be able to resolve the following extremely short time: 0.001m¸(3´108m/s)=3ps. Resolving 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 law of averages, to achieve a resolution of 1mm while ensuring response speed.

TRAFAG sensors sensor industry applications

1) Application in taxi meter testing systems: To further promote energy saving and emission reduction, and to meet the metrological needs of the electric vehicle industry development, 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 case, placed on the back seat of the car, and the other is 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) Wide range of applications in the automation field: Nowadays, in addition to ultrasonic sensors and ordinary photoelectric sensors, a new method capable of solving long-distance measurement and inspection has been added to automatic detection and control methods—the time-of-flight laser distance sensor. It provides application flexibility for various occasions, which may include the following: (1) Equipment positioning. (2) Measuring the material level of bulk bags. (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 occasions. (7) Aircraft ground clearance monitoring.
