FONDERIE ET sensors are the direct source of information for the entire machine vision system. They mainly consist of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of a vision sensor is to acquire the raw images required for processing by the machine vision system. Image sensors can use laser scanners, line-scan and area-scan CCD cameras or TV cameras, as well as newly emerging digital cameras.

FONDERIE ET sensor classification

1) Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output that has a linear or arbitrary functional relationship with the displacement. Ordinary linear potentiometers and rotary 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 a potentiometric displacement sensor is connected to the measured object. The displacement of the object causes a change in resistance 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 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 corresponding to 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 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 determine the actual displacement of the product under test. The high precision and high reliability of these sensors have been widely demonstrated in thousands of practical applications. Since the moving magnetic ring that determines the position 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. The IP protection rating is IP67 or higher. Furthermore, the sensor uses advanced materials and 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; data is not lost even if the power is interrupted and reconnected, and there is no need to re-zero. Since the sensitive element is non-contact, repeated detection does not cause any wear on the sensor, significantly 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 chamber, which travels through the waveguide, creating a circular magnetic field around it. When this magnetic field intersects with the magnetic field generated by the moving magnetic ring sleeved on the waveguide (which represents the position change), 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 chamber. 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 chamber, 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 moving magnetic ring used for measurement does not directly contact the sensor itself, friction and wear are avoided. This results in long service life, strong environmental adaptability, high reliability, good safety, and ease of integration into automated systems. Even in harsh industrial environments, they operate normally. Additionally, they can withstand high temperatures, high pressures, and strong vibrations, and are now widely used in the measurement and control of mechanical displacement.

FONDERIE ET sensor application areas

Widely applicable for level measurement and control in various liquid tanks in the petroleum, chemical, water conservancy, pharmaceutical, food, and beverage industries, 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 moving magnetic ring used for measurement does not directly contact the sensor itself, friction and wear are avoided. This results in long service life, strong environmental adaptability, high reliability, good safety, and ease of integration into automated systems. Even in harsh industrial environments (such as those prone to oil stains, dust, or other contamination), they operate normally [01]. Additionally, 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 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 the petrochemical, aerospace, electric power, and water conservancy industries.
