Germany ZAMAPRES sensor ZAMAPRES model ZAMAPRES price

ZAMAPRES sensors are a general term for sensors that replace contact detection methods such as limit switches, with the purpose of detecting objects without contact. They can convert the movement and presence information of the detected object into electrical signals. Detection methods that convert to electrical signals include methods utilizing eddy currents generated in the metal body of the detected object due to electromagnetic induction, methods utilizing capacitance changes in electrical signals caused by the approach of the detected object, and methods using reed and guide switches.

ZAMAPRES 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 a call, the phone is close to the ear, which can easily lead to accidental operations (for example, cheeks puffing out when laughing may accidentally hang up the call). Therefore, a distance sensor is needed to monitor the distance in real time and automatically turn off the screen when the distance is too close, thereby preventing 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).

ZAMAPRES sensor working principle

When a time-of-flight laser sensor operates, it must measure the transmission time extremely precisely because the speed of light is very 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 resolve the following extremely short time: 0.001m¸(3´108m/s)=3ps. Resolving a time of 3ps places excessive demands on electronic technology and is too costly to implement. 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.

ZAMAPRES sensor industry applications

1) Application in taxi meter testing systems: To further promote energy conservation and emission reduction and address 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 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 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: Today, in addition to ultrasonic sensors and standard photoelectric sensors, a new method capable of 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 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.
