German ATS ELECTRO sensors, ATS ELECTRO models, ATS ELECTRO prices

ATS ELECTRO sensors are the direct source of information for the entire machine vision system. They mainly consist of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of a vision sensor is to acquire the rawest images that the machine vision system needs to process. Image sensors can use laser scanners, line-scan and area-scan CCD cameras, or TV cameras, as well as newly emerging digital cameras.

ATS ELECTRO sensor classification

1) Laser speed measurement: With the rise of modern precision manufacturing and the demand for cost savings, non-contact speed sensors are gradually replacing contact speed sensors. Currently, the most accurate and commonly used non-contact laser speed sensor on the market is the ZLS-Px aberration speed sensor. The aberration speed sensor has two ports: one emission port that emits a LED light source, and one high-speed imaging port that achieves CCD area high-speed imaging comparison. By comparing images at two points in time within an extremely short period, it determines the distance the measured object has moved. Combined with internal algorithms, the sensor outputs the object's speed in real time. As shown in the figure, (1) is the LED light emission port, (2) is the camera reception port, (3) and (4) are terminal blocks, and (5) are mounting screw holes. (1) The LED light emission port emits laser light toward the measured object; after reflection, it reaches the (2) camera reception port. Upon receiving the signal, it is transmitted to the signal processor, which calculates the speed using algorithms. The ZLS-Px aberration speed sensor can simultaneously measure speed and length in two directions. It can detect not only whether the measured object has stopped but also its direction of motion. Mount the sensor on a stable bracket to ensure that excessive vibration is not generated during the rotation of the object, thereby allowing measurement of the rotational angle and speed of the rotating object. 2) Radar speed measurement: Traditional speed measurement mostly involves rotary motion speed and linear motion speed. However, there are many irregular speed measurement scenarios in industrial automation, such as athlete speed measurement, traffic vehicle speed measurement, and golf ball speed measurement. Radar speed sensors can meet these requirements.

ATS ELECTRO sensor principle

A transmissive speed sensor consists of a slotted or notched disk, a light source, and a phototube. When the disk rotates with the shaft under test, light can only reach the phototube through the holes or notches. When the phototube is illuminated, its reverse resistance is very low, thus outputting an electrical pulse signal. When the light source is blocked by the disk, the reverse resistance of the phototube is very high, and there is no signal output at the output terminal. In this way, based on the number of holes or notches on the disk, the rotational speed of the shaft under test can be measured. The number of holes or notches on the disk is usually set to sixty, so for each revolution of the shaft under test, the photoelectric converter outputs 60 pulse signals. If the time base signal of the electronic counter is set to 1s, the rotational speed of the shaft under test can be read directly. The principle of a reflective speed sensor is the same as that of a transmissive one; it converts changes in received light into changes in electrical signals via a phototube, but it obtains pulse signals through light reflection, typically by adhering reflective material to the measurement area of the shaft under test to form a reflective surface. Commonly used reflective materials are specialized speed-measuring reflective paper tapes (adhesive tapes); aluminum foil or other reflective materials can also be used as substitutes; sometimes white paint can be applied to the measurement area to serve as a reflective surface. The emitter and the reflective surface must be properly configured, typically, the distance between them is 5-15M. When the measured shaft rotates, the photoelectric element receives pulsating light, and outputs the corresponding electrical signal to the electronic counter, thereby measuring the rotational speed of the measured shaft. The waveform of the output signal from the photoelectric speed sensor is relatively regular, close to a standard square wave, with almost no interference signals generated. However, for the transmissive type, vibration reduces the service life of the light source, so it is not suitable for use under conditions with strong vibration. The reflective type has no mechanical connection with the measured shaft, making it convenient to use.

ATS ELECTRO sensor industry applications

1) Modern vehicles are generally equipped with engine control, autonomous driving, ABS, TRC, automatic door locking, active suspension, guidance systems, electronic instruments, and other devices, all of which require vehicle speed signals. Therefore, the accuracy and stability of the output signal from the vehicle speed sensor will have a significant impact on these control units. Automotive speed sensors mostly adopt a Hall-effect structure. A Hall speed sensor is a magnetoelectric sensor based on the Hall effect, featuring high sensitivity to magnetic fields, stable output signal, high frequency response, strong anti-electromagnetic interference capability, simple structure, and ease of use. It mainly consists of a permanent magnet with a specific number of pole pairs (generally 4 or 8 pairs), a Hall element, a rotating mechanism, and input/output connectors. Its working principle is that when the rotating mechanism of the sensor rotates under external drive, it drives the permanent magnet to rotate, causing the magnetic field passing through the Hall element to change periodically, causes a change in the output voltage of the Hall element, which is processed by subsequent circuits to form a stable pulse voltage signal, serving as the output signal of the vehicle speed sensor. The main electrical technical parameters of Hall-effect speed sensors include: high output voltage, low output voltage, duty cycle, period, rise time, fall time, number of pulses per period, etc., To ensure product performance and reliability, these parameters must be quantitatively tested before leaving the factory. Test systems featuring integration and intelligence, efficient automatic measurement, software computation, and graphical or tabular display of test results are increasingly favored by automotive speed sensor manufacturers. It is a comprehensive testing device developed for performance measurement of commonly used Hall-effect vehicle speed sensors. Considering cost factors, the high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed sensor, and software control is employed to compute the acquired data and process it for graphical display. The completed testing device offers advantages such as high testing accuracy, reliable data communication, a user-friendly graphical interface, strong anti-interference capability, a simple and intuitive testing process, and low system development costs, having good potential for market adoption, therefore, speed sensors will have significant application prospects in vehicle speed detection. 2) The speed sensor of the belt conveyor uses a Hall sensor, which is primarily a sensor that utilizes the Hall effect to achieve magneto-electric conversion, The Hall effect has been under development for more than 100 years since its discovery in 1879, but its application occurred in the 50s of this century, Due to the rapid development of microelectronics, it gained attention and widespread adoption, and various types of Hall elements have been continuously developed. China began to increase research on Hall elements in the 70s of the 20th century, After nearly several decades of research and development, it is now capable of producing Hall elements with various performance characteristics, For example: standard type, high-sensitivity type, low temperature coefficient type, temperature and magnetic field measurement type, and switch-type Hall elements. Due to the characteristics of Hall sensors, such as high sensitivity, good linearity, high stability, small size, and high temperature resistance, they have been widely applied in various industrial fields, including non-electrical quantity measurement and automatic control, computer devices, and modern military technology.
