RHEINTACHO switch German RHEINTACHO model RHEINTACHO price

The RHEINTACHO switch is the direct source of information for the entire machine vision system, mainly composed of one or two image sensors, sometimes accompanied by light projectors and other auxiliary equipment. The main function of the vision sensor is to acquire sufficient raw images for the machine vision system to process. Image sensors can use laser scanners, linear and area array CCD cameras or TV cameras, as well as newly emerging digital cameras.

RHEINTACHO switch classification

1) Potentiometric displacement switch, converting mechanical displacement into resistance or voltage output that is linearly or arbitrarily related to it. Ordinary linear potentiometers and circular potentiometers can be used as linear displacement and angular displacement switches, respectively. However, potentiometers designed for measuring displacement require a definite relationship between displacement change and resistance change. The movable brush of the potentiometric displacement switch 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 stepwise change in resistance based on turn resistance when the brush moves, wire-wound potentiometers exhibit a stepped output characteristic. If such a displacement switch 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 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 determining 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 pollutants, with an IP protection rating of IP67 or higher. 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, generating a strain pulse signal through the intersection of two different magnetic fields. The measuring element is a waveguide, with the sensitive element inside the waveguide made of special magnetostrictive material. The measurement process involves generating a current pulse in the electronics housing of the switch, which transmits 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 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 change, 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 ease of 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.

It can be widely used for level measurement and control of various liquid tanks in industries such as petroleum, chemical, water conservancy, pharmaceuticals, food, and beverages, as well as in aerospace refueling systems, automotive refueling systems, diesel refueling systems, various hydraulic tanks, hydrological monitoring, and water treatment. The magnetostrictive displacement switch is a high-precision, long-stroke absolute position measurement displacement switch manufactured based on the magnetostrictive principle.
