ELIGRAF sensors are devices that convert optical signals into electrical signals. Their operating principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a material absorb photon energy when light strikes certain substances, resulting in corresponding electrical effects. Based on the different manifestations of the photoelectric effect, it is categorized into three types: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells. The performance and characteristic curves of photoelectric devices are analyzed.

ELIGRAF sensor features

High-precision single-axis tilt angle sensors, based on capacitive 3D-MEMS technology, demonstrate exceptional reliability, outstanding stability, and unprecedented high precision across the entire temperature range. The tilt angle sensor series is designed, manufactured, and tested according to the reliability and stability requirements of the automotive industry. The series of tilt angle sensors features significant load capacity and excellent shock durability without requiring additional components. Tilt sensors are part of the analog accelerometer product family and are fully compatible with accelerometers. Tilt sensors allow adjustment of the output frequency and have built-in zero-position adjustment. Zero-adjustment buttons can be customized upon request to achieve zeroing at a specific angle. This is particularly useful for applications measuring relative tilt angles; after use, the sensor can return to the zero position. When used in such applications, simply mount the sensor on a fixed plane and use the zero button to clear the reading before measurement. Subsequent data read from the sensor represents the relative tilt angle with respect to that plane.

ELIGRAF sensor application areas

Using angle sensors to control your wheels allows for indirect obstacle detection. The principle is straightforward: if the motor is running but the gear is not turning, it indicates that your machine is blocked by an obstacle. This technology is simple to use and highly effective; the only requirement is that the moving wheels must not slip on the floor (or slip excessively), otherwise, obstacles cannot be detected. Connecting an idler gear to the motor can avoid this issue. This wheel is not driven by the motor but is rotated by the movement of the device: if the idler wheel stops while the drive wheel is rotating, it indicates that an obstacle has been encountered. Angle sensors are very useful in many situations: controlling the position of arms, heads, and other movable parts. It is worth noting that RCX may be affected in terms of precise detection and counting when the operating speed is too slow or too fast. In fact, the problem does not lie with RCX itself, but with its operating system; if the speed exceeds its specified range, RCX will lose some data. Steve Baker has demonstrated through experiments that a rotational speed between 50 and 300 rpm is a suitable range, within which no data loss occurs. However, at speeds below 12rpm or above 1400rpm, some data loss may occur. In the ranges of 12rpm to 50rpm or 300rpm to 1400rpm, RCX may also occasionally experience data loss.
