German EGE-Elektronik sensors, EGE-Elektronik models, EGE-Elektronik prices

EGE-Elektronik sensors precisely measure the actual displacement of the detected product by detecting the absolute position of a movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of these sensors have been widely applied in thousands of real-world cases. Since the movable magnetic ring used for position determination does not come into direct contact with the sensitive element, the sensor can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust, or other contaminants. In addition, the sensor uses high-tech materials and advanced electronic processing technology, enabling it to operate in high-temperature, high-pressure, and high-vibration environments. The sensor output signal is an absolute displacement value; even if power is interrupted and reconnected, data is not lost, and there is no need to re-zero. Since the sensitive element is non-contact, repeated detection causes no wear on the sensor, greatly improving detection reliability and service life.

EGE-Elektronik 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 higher-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 CCD area high-speed imaging comparison. By comparing images at two instants within an extremely short time, the distance moved by the object is determined, and combined with internal algorithms, the sensor outputs the object's speed in real time. As shown in the figure, (1) LED light emission port, (2) camera reception port, (3), (4) terminal blocks, (5) mounting screw holes. (1) The LED light emission port emits laser light toward the measured object, which reflects to 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, detecting not only whether the 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 rotating object. 2) Radar speed measurement: Traditional speed measurement mostly involves rotary motion speed and linear motion speed, but industrial automation often requires irregular speed measurements, such as athlete speed, traffic vehicle speed, and golf ball speed. Radar speed sensors can meet these requirements.

EGE-Elektronik sensor principle

Transmissive speed sensors consist of a slotted or notched disk, a light source, and a phototube. When the disk rotates with the measured shaft, light reaches the phototube only through the holes or notches. When the phototube is illuminated, its reverse resistance is very low, producing an electrical pulse signal. When the disk blocks the light source, 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 reflective speed sensors is similar to transmissive ones, converting changes in received light into electrical signals via a phototube, but they obtain pulse signals through light reflection. Typically, reflective material is adhered to the measurement area of the measured shaft to form a reflective surface. Common reflective materials include dedicated speed-measurement reflective tape (adhesive tape); aluminum foil or other reflective materials may also be used, and sometimes white paint is applied to the measurement area as a reflective surface. The projector and reflective surface must be properly configured, typically with a distance of 5-15M between them. When the measured shaft rotates, the photoelectric element receives pulsating light and outputs corresponding electrical signals to the electronic counter, thereby measuring the shaft's rotational speed. The waveform of the output signal from photoelectric speed sensors is relatively regular, close to a standard square wave, with almost no interference signals. However, vibration can reduce the lifespan of the light source in transmissive types, making them unsuitable for conditions with strong vibration. Reflective types have no mechanical connection with the measured shaft and are convenient to use.

EGE-Elektronik 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 greatly affect these control units. Vehicle 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 signals, 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 is driven externally, it rotates the permanent magnet, causing periodic changes in the magnetic field passing through the Hall element, which induces changes in the Hall element's output voltage. Subsequent circuit processing forms stable pulse voltage signals as the output of the speed sensor. Key electrical technical parameters for Hall-structure speed sensors include high-level output voltage, low-level output voltage, duty cycle, period, rise time, fall time, and pulses per cycle. To ensure product performance and reliability, these parameters must be quantitatively tested before factory shipment. Test systems featuring integration and intelligence, efficient automated measurement, software computation, and graphical or tabular display of results are increasingly favored by automotive speed sensor manufacturers. A comprehensive testing device has been developed for performance measurement of common Hall-effect vehicle speed sensors. Considering costs, the high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed sensor, and software control implements calculation and graphical display processing of the collected data. The completed testing device offers advantages such as high test precision, reliable data communication, a user-friendly graphical interface, strong anti-interference capability, simple and intuitive detection processes, and low system development costs. It has good market promotion potential, indicating significant application prospects for speed sensors in vehicle speed detection. 2) Speed sensors for belt conveyors use Hall sensors, which are sensors that utilize the Hall effect to achieve magnetoelectric conversion. The Hall effect was discovered in 1879 and has a development history of over 100 years, but its application gained attention and widespread adoption only in the 50s of this century, due to the rapid development of microelectronics, leading to the continuous development of various Hall elements. China began increasing research on Hall elements in the 20s of the 70 century. After nearly several decades of research and development, it is now possible to produce Hall elements with various performances, such as standard type, high-sensitivity type, low-temperature-coefficient type, temperature/magnetic-field sensing type, and switching type. Due to the characteristics of Hall sensors—high sensitivity, good linearity, high stability, small size, and high-temperature resistance—they are widely used in various industrial fields, including non-electrical quantity measurement and automatic control, computer devices, and modern military technology.
