German MAVIL STAMPI sensors, MAVIL STAMPI models, MAVIL STAMPI prices

MAVIL STAMPI sensors are the direct source of information for the entire machine vision system, mainly consisting of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of vision sensors is to acquire the raw 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 the latest digital cameras.

MAVIL STAMPI sensor classification

1) Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output that has a linear or arbitrary functional relationship with it. 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 the increase or decrease in resistance indicates the direction of displacement. Usually, 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 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 voltage can 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 detect the absolute position of a moving magnetic ring using non-contact measurement technology to measure the actual displacement of the product under test; the high precision and high reliability of this sensor have been widely applied in thousands of practical cases. Since the moving magnetic ring that determines the position does not directly contact 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 pollutants, with an IP protection rating of IP67 or higher. 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, repeated detection will not cause any wear to the sensor, greatly improving detection reliability and service life. Magnetostrictive displacement sensors accurately measure position by generating a strain pulse signal through the intersection of two different magnetic fields, based on the magnetostrictive principle. 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 sensor's electronics chamber, 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 moving magnetic ring sleeved on the waveguide (which changes with position), a strain mechanical wave pulse signal is generated inside 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 chamber. Since the transmission time of this strain mechanical wave pulse signal in the waveguide is proportional to the distance between the moving magnetic ring and the electronics chamber, measuring the time allows for highly precise determination of this distance. Since 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, it is not subject to friction or wear, resulting in long service life, strong environmental adaptability, high reliability, good safety, and convenience for system automation. Even in harsh industrial environments, it can operate normally. In addition, it can withstand high temperatures, high pressures, and strong vibrations, and is now widely used in the measurement and control of mechanical displacement.

MAVIL STAMPI 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, it is not subject to friction or wear, 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), it can operate normally [01]. In addition, it can withstand high temperatures, high pressures, and strong vibrations, and is 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, and for strokes above 1 meters, the sensor accuracy can reach 0.02% F, S, with repeatability up to 0.002% F·S, making it widely used in petrochemical, aerospace, electric power, water conservancy, and other industries.
