German KLEINSTEIN sensor KLEINSTEIN model KLEINSTEIN price

KLEINSTEIN sensors are used to detect angles. There is a hole in its body that can accommodate a LEGO axle. When connected to RCX, the angle sensor counts once for every 1/16 revolution of the axle. When rotating in one direction, the count increases; when the direction of rotation changes, the count decreases. The count is related to the initial position of the angle sensor. When initializing the angle sensor, its count value is set to 0. If necessary, you can reset it via programming.

KLEINSTEIN sensor classification

Load cells are divided into 8 types based on conversion methods, including photoelectric, hydraulic, electromagnetic force, capacitive, magnetic pole variation, vibratory, gyroscopic, and resistive strain gauge types, with resistive strain gauge being the most widely used. 1) Photoelectric type: Includes grating and code disk types. Grating sensors convert angular displacement into optoelectronic signals using Moiré fringes formed by gratings. There are two gratings: one fixed grating and one moving grating mounted on the dial shaft. The measured object placed on the weighing platform rotates the dial shaft through a force transmission lever system, driving the moving grating to rotate and causing the Moiré fringes to move. Using phototubes, conversion circuits, and display instruments, the number of shifted Moiré fringes can be calculated to determine the angle of grating rotation, thereby determining and reading the mass of the measured object. Code disk sensors: A code disk (symbol plate) is a piece of transparent glass mounted on the dial shaft, featuring black-and-white codes arranged according to a specific encoding method. When the measured object on the weighing platform causes the dial shaft to rotate via the force transmission lever, the code disk also rotates by a certain angle. Photocells receive light signals passing through the code disk and convert them into electrical signals, which are then digitally processed by circuits, finally displaying the digital value representing the measured mass on the display. Photoelectric sensors were mainly used in electromechanical combination scales. 2) Hydraulic type: Under the action of the gravity P of the measured object, the pressure of the hydraulic oil increases, with the degree of increase proportional to P. By measuring the increased pressure value, the mass of the measured object can be determined. Hydraulic sensors have a simple and robust structure and a large measurement range, but accuracy generally does not exceed 1/100. 3) Capacitive type: It operates based on the direct proportional relationship between the oscillation frequency f of the capacitor oscillator circuit and the distance d between the plates. There are two plates, one fixed and the other movable. When the measured object is loaded onto the weighing platform, the leaf spring deflects, changing the distance between the two plates, which in turn changes the oscillation frequency of the circuit. By measuring the change in frequency, the mass of the measured object on the weighing platform can be calculated. Capacitive sensors consume little power, have low cost, and offer an accuracy of 1/200 to 1/500.

KLEINSTEIN sensor features

Resistors, inductors, and capacitors are the three major categories of passive components in electronics. Capacitive sensors convert changes in the measured quantity into changes in capacitance; essentially, they are capacitors with variable parameters. Capacitive sensors have the following advantages: high impedance, low power consumption, and requiring only very low input energy. They can achieve large change magnitudes, resulting in high signal-to-noise ratios and system stability. Fast dynamic response, with operating frequencies reaching several megahertz; suitable for non-b contact measurements, applicable to both conductive and semiconductor measured objects. Simple structure and strong adaptability, capable of operating in harsh environments such as high/low temperatures and strong radiation, leading to wide application. With the development of electronic technology and computer technology, disadvantages of capacitive sensors, such as susceptibility to interference and distributed capacitance, have been continuously overcome. Additionally, capacitive grid displacement sensors and integrated capacitive sensors have been developed. Therefore, they are widely used in non-electrical quantity measurement and automatic detection, capable of measuring parameters such as pressure, displacement, speed, acceleration, A level, thickness, liquid level, humidity, vibration, and component content. Capacitive sensors have promising development prospects.

KLEINSTEIN sensor installation precautions

1) Handle load cells with care, especially small-capacity sensors with aluminum alloy elastic bodies. Any impact or drop caused by vibration is likely to cause significant output errors. 2) When designing the loading device and during installation, ensure that the line of action of the loading force coincides with the force axis of the load cell to minimize the effects of tilting and eccentric loads. 3) Regarding level adjustment: If using load cells, adjust the installation plane of the base with a spirit level until it is horizontal. If multiple sensors are used for simultaneous measurement, their base installation surfaces should be kept as level as possible to ensure that the force borne by each sensor is basically consistent. 4) Determine the rated load of the sensor used based on the load cell capacity selection specified in its instructions. 5) To prevent chemical corrosion, apply Vaseline to the outer surface of the load cell during installation. Avoid direct sunlight and environments with drastic temperature changes. 6) Install bypasses made of copper braided wire at both ends of the load cell loading device. 7) Do not extend the cable yourself. If extension is absolutely necessary, solder the joints and apply moisture-proof sealant. 8) It is best to use baffles to cover the sensor around the load cell. This prevents debris from falling into the moving parts of the sensor, affecting its measurement accuracy. 9) Keep the sensor cable away from high-power power lines or places with pulse waves. If avoidance is impossible, run the load cell cable separately through an iron pipe and shorten the connection distance as much as possible. 10) Determine the rated load of the sensor used based on the load cell capacity selection specified in its instructions. Although load cells have a certain overload capacity, avoid such situations during installation and use. Even short-term overloading may cause permanent damage to the sensor. 11) For high-precision applications, allow the load cell and instrument to warm up for 30 minutes before use.
