German gehweiler lehn sensors, gehweiler lehn models, gehweiler lehn prices

gehweiler lehn sensors are devices that convert mass signals into measurable electrical signal outputs. When using sensors, the actual working environment of the sensor should be considered first. This is crucial for the correct selection of load cells, as it affects whether the sensor can operate normally, its safety and service life, and even the reliability and safety of the entire weighing system. There are qualitative differences between the old and new national standards in the basic concepts and evaluation methods of the main technical indicators of load cells. The main styles include S type, cantilever type, spoke type, plate ring type, membrane box type, bridge type, column cylinder type, etc.

gehweiler lehn 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 the purpose of measuring displacement 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 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. Due to the fact that the resistance of wire-wound potentiometers changes in steps of turn resistance when the brush moves, their output characteristics are also stepped. If this type of displacement sensor is used as a displacement feedback element in a servo system, excessive step voltage will cause system oscillation. Therefore, the resistance value per turn should be minimized during the manufacture of the potentiometer. Another major disadvantage of potentiometric sensors is that they are prone to wear. Their advantages are: simple structure, large output signal, ease of use, and low price. 2) Magnetostrictive displacement sensors accurately measure the actual displacement value of the detected product by detecting the absolute position of the active magnetic ring through 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 active magnetic ring, which 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 pollution. The IP protection rating is above IP67. In addition, the sensor uses high-tech materials and advanced electronic processing technology, so it can be used 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, the 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, which can greatly improve the reliability and service life of the detection. Magnetostrictive displacement sensors utilize the magnetostrictive principle to accurately measure position by generating a strain pulse signal through the intersection of two different magnetic fields. 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, which is transmitted within the waveguide, thereby generating a circumferential magnetic field outside the waveguide. When this magnetic field intersects with the magnetic field generated by the active magnetic ring sleeved on the waveguide (which acts as 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 is transmitted 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 active magnetic ring and the electronics housing, 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. It adopts a non-contact measurement method. Since the active 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 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.

gehweiler lehn sensor application areas

It can be widely used for level measurement and control of various liquid tanks in industries such as petroleum, chemical, water conservancy, pharmaceutical, food, and beverage, 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. It adopts an internal non-contact measurement method. Since the active 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 convenience for system automation. Even in harsh industrial environments (such as places prone to oil stains, dust, or other pollution), 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. 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, it is widely used in industries such as petrochemical, aerospace, electric power, and water conservancy.
