German ELECTRONXX sensor ELECTRONXX model ELECTRONXX price

ELECTRONXX sensors, also known as linear sensors, are linear devices based on metal induction. The function of a sensor is to convert various measured physical quantities into electrical signals. In production processes, displacement measurement is generally divided into two types: measuring physical dimensions and measuring mechanical displacement. Depending on the form of transformation of the measured variable, displacement sensors can be classified into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are mostly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, and Hall effect displacement sensors. An important advantage of digital displacement sensors is that they facilitate direct input of signals into computer systems. These sensors are developing rapidly and their application is becoming increasingly widespread.

ELECTRONXX sensor classification

1) Laser speed measurement: With the rise of precision manufacturing and the demand for cost savings, non-contact speed sensors are gradually replacing contact speed sensors. Currently, the most common and high-precision 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 high-speed CCD area imaging comparison. By comparing images at two points in time within an extremely short period, the distance moved by the object under test is determined, and the sensor's internal algorithms output 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. The (1) LED light emission port directs laser light at the object under test; 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 object under test has stopped but also its direction of motion. Mount the sensor on a stable bracket to ensure that the rotation of the object does not produce excessive vibration, 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.

ELECTRONXX 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, resulting in the output of an electrical pulse signal. When the light source is blocked by the disk, the reverse resistance of the phototube is very high, and no signal is output. Thus, the rotational speed of the shaft under test can be determined based on the number of holes or notches on the disk. The usual number of disk holes or notches is unclear in the source, so when the shaft under test completes one revolution, 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 similar to that of a transmissive sensor; it converts changes in received light into electrical signal changes via a phototube. However, it obtains pulse signals through light reflection, typically by attaching reflective material to the measurement area of the shaft under test to create a reflective surface. Common reflective materials include special speed-measuring reflective tape (adhesive tape), or aluminum foil and other reflective materials may be used as substitutes. Sometimes, white paint is applied to the measurement area to serve as a reflective surface. The projector and reflective surface must be properly configured, typically with a distance of 5-15M between them. When the shaft under test rotates, the photoelectric element receives pulsating light 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 vibration. Reflective types have no mechanical connection with the shaft under test and are convenient to use.

ELECTRONXX 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 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 magneto-electric sensor based on the Hall effect, It features 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 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 magnet to rotate, causing the magnetic field passing through the Hall element to change periodically, which causes the output voltage of the Hall element to change, 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 output voltage, low 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. It is a comprehensive testing device developed for performance measurement of commonly used Hall-effect vehicle speed sensors. Considering cost, the high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed sensor, and software control is used to calculate and graphically display 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, simple and intuitive testing process, and low system development cost. It has good market potential for widespread adoption, 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 switching 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.
