Klaschka switch Germany Klaschka model Klaschka price

Klaschka switch, also known as a linear switch, is a linear device based on metal induction. The function of the switch is to convert various measured physical quantities into electrical signals. In the production process, displacement measurement is generally divided into two types: measuring physical dimensions and mechanical displacement. Depending on the form of transformation of the measured variable, displacement switches can be divided into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement switches are mostly analog structural types, including potentiometric displacement switches, inductive displacement switches, synchros, capacitive displacement switches, eddy current displacement switches, Hall effect displacement switches, etc. An important advantage of digital displacement switches is that they facilitate direct input of signals into computer systems. This type of switch is developing rapidly and its applications are becoming increasingly widespread.

Klaschka switch classification

1) Potentiometric displacement switch 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 switches, 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 switch is connected to the measured object. The displacement of the object causes a change in resistance at the moving end of the potentiometer. The amount of resistance change reflects the magnitude of 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 corresponding to the turn-to-turn resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement switch is used as a displacement feedback element in a servo system, excessive step voltages may cause system oscillation. Therefore, the resistance per turn should be minimized during the manufacture of the potentiometer. Another major disadvantage of potentiometric switches is their susceptibility to wear. Their advantages include: simple structure, large output signal, ease of use, and low cost. 2) Magnetostrictive displacement switch precisely detects the absolute position of a moving magnetic ring using non-contact measurement technology to measure the actual displacement value of the detected product; the high precision and high reliability of this switch 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 switch can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust, or other contaminants. Its IP protection rating is above IP67. In addition, the switch uses high-tech materials and advanced electronic processing technology, allowing it to operate in high-temperature, high-pressure, and high-vibration environments. The switch 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 switch, greatly improving detection reliability and service life. The magnetostrictive displacement switch accurately measures position by utilizing the magnetostrictive principle, where the intersection of two different magnetic fields generates a strain pulse signal. 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 switch, 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 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 moving 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 variation, and no periodic recalibration is required. The magnetostrictive displacement switch is a high-precision, long-stroke absolute position measurement displacement switch manufactured based on the magnetostrictive principle. It adopts a non-contact measurement method. Since the moving magnetic ring used for measurement and the switch 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. Furthermore, it can withstand high temperatures, high pressures, and strong vibrations, and is now widely used in the measurement and control of mechanical displacement.

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 strokes over 1 meters, the switch 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.
