German VES SVET sensor VES SVET model VES SVET price

VES SVET sensor precisely measures the actual displacement of the detected product by detecting the absolute position of the movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of this sensor have been widely applied in thousands of practical cases. Since the movable magnetic ring used for position determination 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 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 the power supply is interrupted and reconnected, data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, repeated detection will not cause any wear to the sensor, greatly improving detection reliability and service life.

VES SVET sensor classification

1) Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output that has a linear or arbitrary functional relationship. 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 brush 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 amount of resistance change reflects the magnitude of the displacement, while an increase or decrease in resistance indicates the direction of displacement. Typically, a 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 brush 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 voltage may cause system oscillation. Therefore, the resistance per turn should be minimized during potentiometer manufacturing. Another major disadvantage of potentiometric sensors is their susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost. 2) Magnetostrictive displacement sensors precisely measure the actual displacement of the detected product by detecting the absolute position of the movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of this sensor have been widely applied in thousands of practical cases. Since the movable magnetic ring used for position determination 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 contaminants, with an IP protection rating of IP67 or higher. 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 the power supply is interrupted and reconnected, data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, repeated detection will not cause any wear to the sensor, greatly improving detection reliability and service life. Magnetostrictive displacement sensors accurately measure position based on the magnetostrictive principle, generating a strain pulse signal through the intersection of two different magnetic fields. The measuring element is a waveguide, with the sensitive element inside made of special magnetostrictive material. The measurement process involves generating a current pulse in the sensor's electronics housing, which travels through the waveguide, creating a circumferential magnetic field outside the waveguide. When this magnetic field intersects with the magnetic field generated by the movable magnetic ring sleeved on the waveguide (which changes with 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 movable 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 variation, 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 employ a non-contact measurement method; since the movable magnetic ring used for measurement and the sensor itself do not come into direct contact, they are not subject to friction or wear, resulting in long service life, strong environmental adaptability, high reliability, good safety, and ease of integration into automated systems. They can operate normally even in harsh industrial environments. Furthermore, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement.

VES SVET sensor application areas

Widely used for level measurement and control in various liquid tanks in industries such as petroleum, chemical, water conservancy, pharmaceuticals, food, and beverages, as well as in 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 employ an internal non-contact measurement method; since the movable magnetic ring used for measurement and the sensor itself do not come into direct contact, they are not subject to friction or wear, resulting in long service life, strong environmental adaptability, high reliability, good safety, and ease of integration into automated systems. They can operate normally even in harsh industrial environments (such as those prone to oil stains, dust, or other contamination) [01]. Furthermore, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement. Their stroke can reach 3 meters or more, 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.
