German KELMA sensors KELMA models KELMA prices

KELMA sensors are measurement feedback devices that operate based on the optical principle of gratings. Grating scales are frequently used in the closed-loop servo systems of CNC machine tools and can be used to detect linear or angular displacement. The measurement output signal is a digital pulse, characterized by a large detection range, high detection accuracy, and fast response speed. For example, in CNC machine tools, they are often used to detect the coordinates of tools and workpieces to observe and track tool path errors, thereby compensating for tool motion errors. Depending on the manufacturing method and optical principle, grating scales are divided into transmission gratings and reflection gratings.

KELMA sensor features

High-precision single-axis tilt angle sensors based on capacitive 3D-MEMS technology demonstrate excellent reliability, superior stability, and unprecedented high precision across the entire temperature range. The tilt angle sensor series is designed, produced, and tested according to the reliability and stability requirements of the automotive industry. The series of tilt angle sensors has significant load capacity and very good impact 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; a zero-position adjustment button can be customized as required to achieve zeroing at a specific angle. This is very useful for applications measuring relative tilt angles, allowing the sensor to return to zero after use. When using the tilt sensor in such applications, simply fix the sensor to a specific plane and use the zero button to clear the reading before measurement; subsequent data read by the sensor will represent the relative tilt angle with respect to that plane.

KELMA sensor application areas

Using angle sensors to control your wheels can indirectly detect obstacles. The principle is very simple: if the motor is running but the gear is not turning, it indicates that your machine is blocked by an obstacle. This technology is very simple to use and highly effective; the only requirement is that the moving wheel must not slip on the floor (or slip too frequently), otherwise you will be unable to detect obstacles. If an idler gear connected to the motor is used, this problem can be avoided; this wheel is not driven by the motor but is driven by the movement of the device: if the idler wheel stops while the drive wheel is rotating, it indicates that you have hit an obstacle. In many cases, angle sensors are very useful: controlling the position of arms, heads, and other movable parts. It is worth noting that when the operating speed is too slow or too fast, RCX will be affected in terms of accurate detection and counting. 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 proven through experiments that a rotational speed between 50 and 300 rpm is a relatively suitable range, within which there will be no data loss issues. However, in the range below 12rpm or above 1400rpm, some data loss will occur. In the ranges of 12rpm to 50rpm or 300rpm to 1400rpm, RCX may also occasionally experience data loss issues.
