KOBOLD Messring sensors are components that convert changes in non-electrical quantities (such as speed and pressure) into changes in electrical quantities. Depending on the non-electrical quantity converted, they can be classified as pressure sensors, speed sensors, temperature sensors, etc., serving as parts and accessories for measurement and control instruments and equipment.

KOBOLD Messring sensor classification

Load cells are divided into 8 categories based on conversion methods, including photoelectric, hydraulic, electromagnetic force, capacitive, magnetic pole variation, vibratory, gyroscope, and resistance strain gauge types, with resistance 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 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. By using photocells, conversion circuits, and display instruments, the number of moved 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 rotates the dial shaft 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 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 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 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 and consequently changing 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.

KOBOLD Messring sensor features

Resistors, inductors, and capacitors are the three major types 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 offer 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. They have fast dynamic response, with operating frequencies reaching several megahertz, allowing for non-b contact measurement, suitable for both conductive and semiconductor measured objects. Their simple structure and strong adaptability allow them to operate 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. Furthermore, 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.

KOBOLD Messring sensor installation precautions

1) Handle load cells with care, especially small-capacity sensors using aluminum alloy elastomers. 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 tilted and eccentric loads. 3) Regarding level adjustment: If using a load cell, adjust the installation plane of its 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, preheat the load cell and instrument for 30 minutes before use.
