German ASC GMBH sensors, ASC GMBH models, ASC GMBH prices

ASC GMBH sensors are devices capable of sensing the approach of objects. They utilize the sensitivity of displacement sensors to nearby objects to detect proximity and output corresponding switching signals; therefore, proximity sensors are often referred to as proximity switches. This is a general term for sensors designed to replace contact-based detection methods such as switches, with the aim of detecting without contacting the object. They can detect movement and presence information of objects and convert it into electrical signals.

ASC GMBH sensor classification

1) Potentiometric displacement sensors convert mechanical displacement into resistance or voltage outputs that have a linear or arbitrary functional relationship with the displacement. Ordinary linear potentiometers and circular potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, potentiometers designed for displacement measurement require a definite relationship between displacement change and resistance change. The movable wiper of the potentiometric displacement sensor is connected to the measured object. The displacement of the object causes a resistance change at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while an increase or decrease in resistance indicates the direction of displacement. Typically, a power supply voltage is applied to the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps based on the turn-to-turn resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement sensor is used as a displacement feedback element in a servo system, excessive step voltages may cause system oscillation. Therefore, the resistance per turn should be minimized during potentiometer manufacturing. Another major disadvantage of potentiometric sensors is susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost. 2) Magnetostrictive displacement sensors accurately measure the actual displacement value of the detected product by non-contact measurement and control technology to detect the absolute position of a moving magnetic ring. The high precision and high reliability of this sensor have been widely applied in thousands of practical cases. Since the moving magnetic ring determining the position and the sensitive element do not come into direct contact, the sensor can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust, or other pollution. The IP protection rating is above IP67. In addition, the sensor uses high-tech materials and advanced electronic processing technology, allowing it to operate in high-temperature, high-pressure, and high-vibration environments. The sensor output signal is an absolute displacement value; even if the power is interrupted and reconnected, data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, continuous repeated detection will not cause any wear to the sensor, significantly improving detection reliability and service life. Magnetostrictive displacement sensors utilize the magnetostrictive principle, generating a strain pulse signal through the intersection of two different magnetic fields to accurately measure position. The measuring element is a waveguide, and the sensitive element inside the waveguide is made of special magnetostrictive material. The measurement process involves generating a current pulse in the electronics housing of the sensor. This current pulse travels through the waveguide, creating a circumferential magnetic field outside the waveguide. When this magnetic field intersects with the magnetic field generated by the moving magnetic ring sleeved on the waveguide (which changes position), a strain mechanical wave pulse signal is generated within the waveguide due to the magnetostrictive effect. This strain mechanical wave pulse signal travels at a fixed speed of sound and is quickly detected by the electronics housing. Since the transmission time of this strain mechanical wave pulse signal within the waveguide is proportional to the distance between the moving magnetic ring and the electronics housing, measuring the time allows for highly precise determination of this distance. Because the output signal is a true absolute value, rather than a proportional or amplified signal, there is no signal drift or value change, and no periodic recalibration is required. Magnetostrictive displacement sensors are high-precision, long-stroke absolute position measurement displacement sensors manufactured based on the magnetostrictive principle. They adopt a non-contact measurement method. Since the moving magnetic ring used for measurement does not directly contact the sensor itself, friction and wear are avoided, resulting in long service life, strong environmental adaptability, high reliability, good safety, and convenience for system automation. Even in harsh industrial environments, they can operate normally. Furthermore, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement.

ASC GMBH sensor application areas

Widely applicable for level measurement and control of various liquid tanks in industries such as petroleum, chemical, water conservancy, pharmaceuticals, food, and beverages, as well as aerospace refueling systems, automotive refueling systems, diesel refueling systems, various hydraulic tanks, hydrological monitoring, and water treatment. Magnetostrictive displacement sensors are high-precision, long-stroke absolute position measurement displacement sensors manufactured based on the magnetostrictive principle. They adopt an internal non-contact measurement method. Since the moving magnetic ring used for measurement does not directly contact the sensor itself, friction and wear are avoided, resulting in long service life, strong environmental adaptability, high reliability, good safety, and convenience for system automation. Even in harsh industrial environments (such as those prone to oil stains, dust, or other contamination), they can operate normally [01]. In addition, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement. Its stroke can reach 3 meters or longer, with a nominal accuracy of 0.05% F·S. For sensors with a stroke of 1 meters or more, the accuracy can reach 0.02% F, S, and repeatability can reach 0.002% F·S. Therefore, they are widely used in industries such as petrochemical, aerospace, electric power, and water conservancy.
