German MATOKEM sensors, MATOKEM models, MATOKEM prices

MATOKEM sensors are sensors that use laser technology for measurement. They consist of a laser, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument; their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference.

MATOKEM sensor classification

Load cells are divided into 8 categories 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 use Moiré fringes formed by gratings to convert angular displacement into photoelectric signals. There are two gratings: one fixed grating and one moving grating mounted on the dial shaft. The object being measured on the load platform rotates the dial shaft through a force transmission lever system, driving the moving grating to rotate and causing the Moiré fringes to move. By using a phototube, conversion circuit, and display instrument, the number of moved Moiré fringes can be calculated to determine the angle of grating rotation, thereby determining and reading the mass of the object. Code disk sensor: The 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 object on the load platform causes the dial shaft to rotate via the force transmission lever, the code disk also rotates by a certain angle. A photocell receives the light signal passing through the code disk and converts it into an electrical signal, which is then digitally processed by the circuit, 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 increase in pressure, the mass of the object can be determined. Hydraulic sensors have a simple and robust structure and a large measuring range, but accuracy generally does not exceed 1/100. 3) Capacitive type: It operates based on the 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 object is loaded onto the load 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 object on the load platform can be determined. Capacitive sensors consume little power, have low cost, and have an accuracy of 1/200 to 1/500.

MATOKEM sensor features

Resistors, inductors, and capacitors are the three major types of passive components in electronics. A capacitive sensor is a sensor that converts changes in the measured quantity into changes in capacitance; it is essentially a capacitor with variable parameters. Capacitive sensors have the following advantages: high impedance, low power, and requiring only very low input energy. They can achieve large change magnitudes, resulting in high signal-to-noise ratio and system stability. Fast dynamic response, with operating frequencies reaching several megahertz, suitable for non-b contact measurement; the measured object can be either a conductor or a semiconductor. Simple structure, strong adaptability, capable of operating in harsh environments such as high/low temperatures and strong radiation, with wide application. With the development of electronic technology and computer technology, disadvantages of capacitive sensors, such as susceptibility to interference and influence from 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, rotational speed, acceleration, A degree, thickness, liquid level, humidity, vibration, and component content. Capacitive sensors have good development prospects.

MATOKEM sensor installation precautions

1) Handle load cells with care, especially small-capacity sensors using aluminum alloy as the elastic body. 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 inclined and eccentric loads. 3) Regarding level adjustment. If using load cells, the installation plane of the base must be adjusted with a spirit level until horizontal. If multiple sensors are measuring simultaneously, their base installation surfaces should be kept on the same horizontal plane as much as possible. The main purpose of this is 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 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) Connect bypasses made of copper braided wire to 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 in its instructions. Although load cells have a certain overload capacity, such situations should be avoided during installation and use. Sometimes, short-term overload can 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.
