Germany MP-Sensor sensor MP-Sensor model MP-Sensor price

MP-Sensor sensors are a general term for sensors designed to detect objects without contact, replacing contact-based detection methods such as limit switches. They convert the movement and presence information of the detected object into electrical signals. Detection methods that convert to electrical signals include those utilizing eddy currents generated in the metal body of the detected object due to electromagnetic induction, those detecting capacitance changes in the electrical signal caused by the approach of the detected object, and those using reed and guide switches.

MP-Sensor sensor classification

1) Potentiometric displacement sensor converts 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 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 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. In wire-wound potentiometers, the resistance changes in steps based on the turn-to-turn resistance as the wiper moves, so 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 can 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 cost. 2) Magnetostrictive displacement sensors precisely measure the actual displacement value of the detected product by detecting the absolute position of a movable magnetic ring using non-contact measurement technology. The high precision and high reliability of this sensor have been widely applied in thousands of actual cases. Since the movable 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 pollutants. The IP protection rating is above IP67. In addition, the sensor uses high-tech materials and advanced electronic processing technology, allowing it to 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, 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 utilizing the magnetostrictive principle, 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. This current pulse 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 acts as the position variable), 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 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 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 convenience for 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.

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 petrochemical, aerospace, electric power, water conservancy, and other industries.
