Germany PCE DEUTSCHLAND sensor PCE DEUTSCHLAND model PCE DEUTSCHLAND price

PCE DEUTSCHLAND 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 to electrical signals include those utilizing eddy currents generated in the metal body of the detection object due to electromagnetic induction, methods based on capacitance changes in the electrical signal caused by the approach of the detected object, and methods using reed and guided switches.

PCE DEUTSCHLAND 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 while laughing may easily hang up the call). Therefore, a distance sensor is 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 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).

PCE DEUTSCHLAND 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 utilizing a simple statistical principle, namely the law of averages, to achieve a resolution of 1mm while ensuring response speed.

PCE DEUTSCHLAND sensor industry applications

1) Application in taxi meter testing systems: To further save energy and reduce emissions, and to address the metrology 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 similar in size to 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 about seven to eight minutes. 2) Extensive uses in the automation field: Nowadays, in addition to ultrasonic sensors and standard photoelectric sensors, automatic detection and control methods have added a new method capable of solving long-distance measurement and inspection—time-of-flight laser distance sensors. It provides application flexibility for various occasions, which may include the following: (1) Equipment positioning. (2) Measuring the material level of 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.
