German RUBI ZETA sensors, RUBI ZETA models, RUBI ZETA prices

RUBI ZETA 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.

RUBI ZETA sensor classification

1) Laser speed measurement: With the rise of modern precision manufacturing and the demand for cost savings, non-contact speed sensors will gradually replace 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: a transmission port that emits LED light sources, and a high-speed imaging port that achieves CCD area high-speed imaging comparison. By comparing images at two instants within an extremely short time, 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 directs laser light at 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 the rotating object does not generate excessive vibration during rotation, thereby allowing measurement of the rotation angle and rotational speed of the measured object. 2) Radar speed measurement: Traditional speed measurement mostly involves rotary motion speed measurement and linear motion speed measurement. 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.

RUBI ZETA 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 measured shaft, light can only reach the phototube through the holes or notches. When the phototube is illuminated, its reverse resistance is very low, outputting an electrical pulse signal. When the light source is blocked by the disk, the phototube's reverse resistance is very high, and no signal is output. Thus, based on the number of holes or notches on the disk, the rotational speed of the measured shaft can be determined. The usual number of disk holes or notches is unclear in the source, so each revolution of the measured shaft allows the photoelectric converter to output 60 pulse signals. If the time base signal of the electronic counter is set to 1s, the rotational speed of the measured shaft can be read directly. The principle of a reflective speed sensor is similar to that of a transmissive one; it converts changes in sensed light into changes in electrical signals via a phototube. However, it obtains pulse signals through light reflection, typically by attaching reflective material to the measurement area of the measured shaft to form a reflective surface. Commonly used reflective materials include special speed-measurement reflective tape (adhesive tape); aluminum foil or other reflective materials can also be used. Sometimes, white paint is applied to the measured area to serve as a reflective surface. The projector and the reflective surface must be properly configured, typically with a distance of 5-15M between them. When the measured shaft rotates, the photoelectric element receives pulsed illumination and outputs corresponding electrical signals to the electronic counter, thereby measuring the rotational speed of the shaft. The waveform of the output signal from photoelectric speed sensors is relatively regular, close to a standard square wave, with almost no interference signals generated. However, vibration in transmissive types can reduce the lifespan of the light source, making them unsuitable for conditions with strong vibrations. Reflective types have no mechanical connection with the measured shaft and are easy to use.

RUBI ZETA 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 these devices require the vehicle speed signal. Therefore, The accuracy and stability of the output signal from the sensor measuring vehicle running speed 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, Characterized by high sensitivity to magnetic fields, stable output signal, high frequency response, strong resistance to electromagnetic interference, simple structure, and ease of use. It mainly consists of permanent magnets with a specific number of pole pairs (generally 4 or 8 pairs), Hall elements, a rotating mechanism, and input/output connectors. Its working principle is that when the sensor's rotating mechanism rotates under external drive, it drives the permanent magnets to rotate, causing periodic changes in the magnetic field passing through the Hall element, which causes changes in the output voltage of the Hall element, forming a stable pulse voltage signal through subsequent circuit processing, serving as the output signal of the vehicle speed sensor. The main electrical technical parameters of Hall-structure speed sensors include: high-level output voltage, low-level output voltage, duty cycle, period, rise time, fall time, number of pulses per cycle, etc. To ensure product performance reliability, these parameters must be quantitatively tested before leaving the factory. Test systems featuring integration and intelligence, efficient automatic measurement, software calculation, and graphical or tabular display of test results are increasingly favored by automotive speed sensor manufacturers. A comprehensive testing device developed for performance measurement of commonly used Hall-effect vehicle speed sensors. Based on cost considerations, the high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed sensor, and software control is used to implement calculation and graphical display processing of the acquired data. The completed testing device offers advantages such as high testing precision, reliable data communication, a user-friendly graphical interface, strong anti-interference capability, a simple and intuitive testing process, and low system development cost, and has good market promotion potential, Therefore, speed sensors have significant application prospects in vehicle speed detection. 2) The speed sensor of the belt conveyor adopts a Hall sensor, which is primarily a sensor that utilizes the Hall effect to achieve magneto-electric conversion, The Hall effect has a development history of more than 100 years since it was discovered in 1879, but its application began in the 50s of this century, Due to the rapid development of microelectronics, it has 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 possible to produce Hall elements with various performance characteristics, such as: standard type, high sensitivity type, low temperature coefficient type, temperature and magnetic 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, automatic control, computer devices, and modern military technology.
