German MANTHEY instruments sensors, MANTHEY instruments models, MANTHEY instruments prices

MANTHEY instruments sensors are devices capable of detecting the approach of objects. They utilize the sensitivity of displacement sensors to nearby objects to identify proximity and output corresponding switching signals; therefore, proximity sensors are often referred to as proximity switches. This is a general term for sensors designed to replace contact-based detection methods such as switches, with the aim of non-contact detection of the target object. They can detect movement and presence information of the object and convert it into electrical signals.

MANTHEY instruments 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, which can easily lead to accidental operations (such as cheeks puffing out during laughter accidentally hanging up the call). Therefore, distance sensors are needed 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 in 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).

MANTHEY instruments sensor working principle

When time-of-flight laser sensors are in operation, the transmission time must be measured 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.

MANTHEY instruments 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 host 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 about seven to eight minutes. 2) Extensive use 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 problems has been added to automatic detection and control methods—the time-of-flight laser distance sensor. 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.
