steute sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and have been widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Distance sensors can be classified into optical distance sensors, infrared distance sensors, ultrasonic distance sensors, etc., based on their working principles. Most distance sensors used in mobile phones are infrared distance sensors, which feature an infrared emitting tube and an infrared receiving tube. When the infrared rays emitted by the transmitting tube are received by the receiving tube, it indicates a short distance, requiring the screen to be turned off to prevent accidental operation. When the receiving tube does not receive the infrared rays emitted by the transmitting tube, it indicates a long distance, and there is no need to turn off the screen. The working principles of other types of distance sensors are similar, determining distance by emitting and receiving a certain substance, such as ultrasonic waves or light pulses.

steute sensor classification

1) Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output with 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 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. Typically, a power supply voltage is applied to the potentiometer to convert the resistance change into a voltage output. Due to the stepwise change in resistance per turn as the wiper moves, wire-wound potentiometers exhibit 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 value 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 of the detected product by detecting the absolute position of a moving magnetic ring using non-contact measurement technology. 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 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 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; even if the power is interrupted and reconnected, data is not lost, and re-zeroing is not required. Since the sensitive element is non-contact, repeated detection does 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, 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 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 within the waveguide due to magnetostriction. 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. 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 regular recalibration is not 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 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 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.

steute 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 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 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. 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 industries such as petrochemical, aerospace, electric power, and water conservancy.
