German TOX PRESSOTECHNIK sensors, TOX PRESSOTECHNIK models, TOX PRESSOTECHNIK prices

TOX PRESSOTECHNIK sensors are components that convert changes in non-electrical quantities (such as speed and pressure) into changes in electrical quantities. Depending on the non-electrical quantity converted, they can be classified into pressure sensors, speed sensors, temperature sensors, etc., and serve as parts and accessories for measurement and control instruments and equipment.

TOX PRESSOTECHNIK sensor classification

Lasers can be divided into 4 types based on the working medium. (1) Solid-state lasers: The working medium is solid. Common types include ruby lasers, neodymium-doped yttrium aluminum garnet lasers (i.e., YAG lasers), and neodymium glass lasers. Their structures are roughly similar, characterized by compactness, robustness, and high power. Neodymium glass lasers offer the highest pulsed output power, reaching tens of megawatts. (2) Gas lasers: The working medium is gas. Various gas atomic, ion, metal vapor, and gas molecular lasers are available. Common types include carbon dioxide lasers, helium-neon lasers, and carbon monoxide lasers. Shaped like ordinary discharge tubes, they feature stable output, good monochromaticity, and long service life, but have lower power and conversion efficiency. (3) Liquid lasers: These can be further divided into chelate lasers, inorganic liquid lasers, and organic dye lasers, with organic dye lasers being the most important. Their key feature is continuously tunable wavelength. (4) Semiconductor lasers: A relatively newer type of laser, with gallium arsenide lasers being the more mature variant. They are characterized by high efficiency, small size, light weight, and simple structure, making them suitable for carriage on aircraft, warships, tanks, and by infantry. They can be made into rangefinders and sights. However, they have lower output power, poorer directionality, and are significantly affected by ambient temperature.

TOX PRESSOTECHNIK sensor principle

When a laser sensor operates, a laser diode first emits a laser pulse toward the target. After reflection from the target, the laser scatters in various directions. Part of the scattered light returns to the sensor receiver, where it is received by the optical system and imaged onto an avalanche photodiode. An avalanche photodiode is an optical sensor with internal amplification capability, enabling it to detect extremely weak light signals and convert them into corresponding electrical signals. A common type is the laser distance sensor, which determines the target distance by recording and processing the time elapsed from the emission of the light pulse to its reception. Laser sensors must measure the transmission time with extreme precision due to the high speed of light.

TOX PRESSOTECHNIK sensor applications

Oversize vehicle width and height detection: Laser sensors are used for rapid measurement. An PC industrial PC and the network kernel of the visualization programming software VB enable real-time data transmission and processing with the sensors. User-friendly HMI control software has also been designed. Field test data show that the system offers good real-time performance and high measurement accuracy, demonstrating practical value. Highway toll stations: Used at highway toll stations for vehicle counting and safety protection. Malaysia's Teras company has deployed hundreds of BEA laser sensors in its manual and automatic toll collection systems. The laser sensors use the Time-of-Flight (TOF) measurement principle to form 4 planes within the detection zone for vehicle monitoring. The product also features anti-rear-end collision and vehicle safety protection functions. Compared to traditional light curtains, laser sensors offer advantages such as high sensitivity, high accuracy, easy installation, cost-effectiveness, and strong stability. Google's second-generation driverless car: Equipped with laser sensors. In Google's second-generation autonomous vehicle prototype, the top-mounted laser sensor remains quite prominent, while other sensors are discreetly integrated. Distinctive Google driverless car logos are affixed to the front, rear, and sides of the vehicle. The control and driving principle of the Google driverless car involves numerous sensors installed around the vehicle that continuously collect precise data about the vehicle itself and its surroundings. An onboard processor analyzes and computes this data to control the vehicle's movement. The driverless car uses GPS devices and sensors to accurately determine the vehicle's position and forward speed, identifying surrounding pedestrians, vehicles, bicycles, traffic lights, and many other objects. The roof of this Lexus features a 360° rotating laser holographic sensor, which can almost simultaneously sense conditions in front of, beside, and behind the vehicle. Data collected by the sensor is transmitted via green data cables to a processor located at the right rear of the vehicle. This laser sensor also enables global precise positioning for the driverless car. The original L emblem on the front of the Lexus was removed and replaced with a radar sensor to measure forward distance and vehicle speed, allowing assessment of traffic conditions ahead and controlling safe acceleration and deceleration. Position sensors are also mounted on the wheel hubs to detect wheel rotation, aiding in vehicle localization. The heart of the Google driverless car—the processor—is located at the right rear of the vehicle. Data from all sensors is transmitted here via data cables for software-based analysis and processing, enabling precise sensing and judgment of different objects near the driverless car. In addition to analyzing and judging the current positions of objects around the driverless car, the software calculates and accurately predicts the potential next position of each object. Finally, the driverless car makes safe driving decisions based on all collected data, including controlling vehicle speed and maintaining distances from surrounding vehicles.
