German RUBINETTERIE sensors RUBINETTERIE models RUBINETTERIE prices

RUBINETTERIE sensors precisely measure the actual displacement of the detected product by detecting the absolute position of a movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of these sensors have been widely applied in thousands of practical cases. Since the movable magnetic ring used for position determination and the sensitive element do not come into direct contact, the sensors can be used in extremely harsh industrial environments and are not easily affected by oil stains, solutions, dust, or other contaminants. In addition, the sensors use high-tech materials and advanced electronic processing technology, enabling them to operate in high-temperature, high-pressure, and high-vibration environments. The sensor output signal is an absolute displacement value; even if power is interrupted and reconnected, data is not lost, and re-zeroing is not required. Since the sensitive element is non-contact, repeated detection causes no wear to the sensor, significantly improving detection reliability and service life.

RUBINETTERIE sensor operating principle

Photoelectric sensors achieve control by converting changes in light intensity into changes in electrical signals. Generally, photoelectric sensors consist of three parts: a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam toward the target; the emitted light beam generally comes from semiconductor light sources, such as light-emitting diodes (LED), laser diodes, and infrared emitting diodes. The light beam is emitted continuously, or the pulse width is varied. The receiver consists of photodiodes, phototransistors, and photocells. Optical components such as lenses and apertures are installed in front of the receiver. Behind it is the detection circuit, which filters out valid signals and applies them. In addition, structural components of photoelectric switches include emitter plates and optical fibers.

RUBINETTERIE sensor classification

1) Slot-type photoelectric sensors: A slot-type photoelectric sensor is formed by mounting a light emitter and a receiver face-to-face on opposite sides of a slot. The emitter emits infrared or visible light, which the receiver detects when unobstructed. However, when the detected object passes through the slot, the light is blocked, causing the photoelectric switch to actuate and output a switching control signal that cuts off or connects the load current, thereby completing a control action. Due to limitations imposed by the overall structure, the detection distance of slot-type switches is generally only a few centimeters. 2) Through-beam photoelectric sensors: Separating the emitter and receiver increases the detection distance; an emitter and a receiver form a separated through-beam photoelectric switch, referred to as a through-beam photoelectric switch. The detection distance of through-beam photoelectric switches can reach several meters or even tens of meters. When using through-beam photoelectric switches, the emitter and receiver are installed on opposite sides of the path through which the detected object passes; when the object passes, it blocks the light path, and the receiver actuates to output a switching control signal. 3) Retro-reflective photoelectric switches: The emitter and receiver are housed in the same unit, with a reflector plate installed in front; this uses the reflection principle to perform photoelectric control and is called a retro-reflective (or mirror-reflective) photoelectric switch. Under normal conditions, the light emitted by the emitter is reflected back by the reflector plate and received by the receiver; once the detected object blocks the light path and the receiver no longer receives light, the photoelectric switch actuates and outputs a switching control signal. 4) Diffuse-reflective photoelectric switches: The detection head of a diffuse-reflective photoelectric switch also contains an emitter and a receiver, but there is no reflector plate in front. Under normal conditions, the receiver does not detect the light emitted by the emitter. During detection, when the detected object passes, it blocks the light and reflects part of it back; the receiver then receives the light signal and outputs a switching signal.

RUBINETTERIE sensor application cases

1) Application of photoelectric sensors in laser weapons: Because photoelectric sensors are particularly sensitive to infrared radiation, visible light, or both, they are more likely to become targets of laser attacks. In addition, electronic systems and the sensors themselves are highly susceptible to interference from thermal noise and electromagnetic noise generated by lasers, preventing normal operation. Methods by which battlefield laser weapons attack photoelectric sensors mainly include the following: using a laser beam of appropriate energy to "blind" the sensor, rendering it unable to detect or continue tracking already detected targets. Alternatively, if the sensor is guiding a weapon toward a target, blinding causes it to lose the target. In summary, because sensors play an increasingly important role on the battlefield and are vulnerable to laser attacks, they have become the preferred targets of low-energy laser weapons. 2) Application of photoelectric sensors in automatic meter reading systems: With the development of microelectronics, sensor technology, computer technology, and modern communications, photoelectric sensors can be used to develop automatic meter reading systems. The aluminum disk of an electricity meter rotates under torque generated by eddy currents and magnetic fields. Using photoelectric sensors converts the number of rotations of the aluminum disk into pulse counts. For example, by partially blackening a rotating shiny aluminum disk and pairing it with a reflective photoelectric emitter-receiver pair, pulses are generated at the blackened areas as the disk rotates; the number of rotations is sampled and converted into corresponding pulse counts, then sent via an optocoupler isolation circuit to the T0 port of the CPU for counting processing. Using optocoupler isolators effectively prevents interference signals from entering the microcomputer. Combined with other transmission methods, this forms an automatic meter reading system. 3) Application of photoelectric sensors in monitoring smoke and dust pollution: Photoelectric sensors are small electronic devices that detect changes in received light intensity, achieving control functions by converting changes in light intensity into changes in electrical signals. Due to characteristics such as non-contact operation, fast response, and reliable performance, photoelectric sensors are widely used in industrial automation equipment and robotics. We can leverage the characteristics of photoelectric sensors to detect smoke and dust conditions, so the strength of the photoelectric sensor output signal reflects changes in flue gas turbidity. 4) Hygienic washdown-resistant photoelectric sensors: Washdown-resistant sensors provide extremely high reliability and ease of use while minimizing operating costs. Equipped with IO-Link interfaces and the proTect+ sealing concept, which significantly extends service life, these two new sensors are suitable for demanding application environments and represent an ideal solution for the food and beverage industry.
