German KLARIG sensor KLARIG model KLARIG price

KLARIG sensors, also known as torque sensors, torsion sensors, torque transducers, or torque meters, are divided into two main categories: dynamic and static. Dynamic torque sensors are also referred to as torque transducers, torque-speed sensors, non-contact torque sensors, or rotary torque sensors. Torque sensors detect the twisting moment on various rotating or non-rotating mechanical components. They convert the physical changes in torsional force into precise electrical signals. Torque sensors can be used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches, offering advantages such as high precision, fast frequency response, good reliability, and long service life.

KLARIG Sensor Classification

Lasers can be classified into 4 types based on their working medium. (1) Solid-state lasers: The working medium is solid. Common examples 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 achieve 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 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 due to their 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 use in aircraft, warships, tanks, and as portable equipment for infantry. They can be made into rangefinders and sights. However, they have lower output power, poorer directionality, and are significantly affected by ambient temperature.

KLARIG Sensor Principle

When a laser sensor operates, a laser diode first emits a laser pulse toward the target. After reflecting off the target, the laser scatters in various directions. Part of the scattered light returns to the sensor receiver, where it is captured by the optical system and imaged onto an avalanche photodiode. An avalanche photodiode is an optical sensor with internal amplification capabilities, allowing 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 transmission time with extreme precision due to the high speed of light.

KLARIG 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 upper-computer control software has also been designed. Field test data indicate that the system offers good real-time performance and high measurement accuracy, demonstrating practical value. Highway toll stations: Used at highway toll booths 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. These 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 higher sensitivity, higher accuracy, easier installation, better cost-performance ratio, and stronger stability. Google's second-generation driverless car: Equipped with laser sensors, the prototype of Google's second-generation autonomous vehicle retains a prominent roof-mounted laser sensor, while other sensors are discreetly integrated. Distinctive Google self-driving car logos are affixed to the front, rear, and sides of the vehicle. The control and driving principle involves numerous sensors installed around the car continuously collecting precise data about the vehicle itself and its surroundings. An onboard processor analyzes and computes this data to control the vehicle's movement. The autonomous vehicle uses GPS devices and sensors to accurately determine its position and forward speed, identifying pedestrians, vehicles, bicycles, traffic lights, and many other objects nearby. The Lexus vehicle features a 360° rotating laser holographic sensor on its roof, capable of simultaneously sensing conditions in front, to the sides, and behind the vehicle. Data collected by the sensor is transmitted via green data cables to a processor located at the rear right side of the vehicle. This laser sensor also enables global precise positioning for the autonomous 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 for assessment of traffic conditions ahead and controlled 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 self-driving car—the processor—is located at the rear right side. 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 autonomous vehicle. In addition to analyzing and judging the current positions of objects around the vehicle, the software calculates and accurately predicts the potential next positions of each object. Finally, the autonomous vehicle makes safe driving decisions based on all collected data, including controlling speed and maintaining safe distances from surrounding vehicles.
