German DI SAVIOLI sensor, DI SAVIOLI model, DI SAVIOLI price

DI SAVIOLI sensors are a general term for sensors designed to detect objects without contact, replacing contact-based detection methods such as limit switches. They convert information about the movement and presence of an object into electrical signals. Detection methods that convert to electrical signals include those utilizing eddy currents generated in the metal body of the detected object due to electromagnetic induction, those detecting changes in capacitance of the electrical signal caused by the approach of the detected object, and those using reed and guide switches.

DI SAVIOLI sensor classification

Load cells are classified by conversion method into 8 types, 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 weighed on the load-bearing 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 a phototube, conversion circuit, and display instrument, the number of moved Moiré fringes can be calculated to measure 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-bearing platform rotates the dial shaft 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 number representing the measured mass on the display. Photoelectric sensors were mainly used in electromechanical combination scales. 2) Hydraulic type: When subjected to the gravity P of the measured object, the pressure of the hydraulic oil increases, with the 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 measurement range, but the 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-bearing 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-bearing platform can be calculated. Capacitive sensors consume little power, have low cost, and have an accuracy of 1/200 to 1/500.

DI SAVIOLI sensor features

Resistors, inductors and capacitors are the three major categories of passive components in electronic technology. 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 consumption, and very low input energy requirement. They can achieve large signal variations, resulting in a high signal-to-noise ratio and system stability. Fast dynamic response, with operating frequencies up to several megahertz; b contact measurement, suitable for both conductive and semiconductive targets. Simple structure and strong adaptability, capable of operating in harsh environments such as extreme temperatures and strong radiation, with wide applications. With the development of electronic and computer technologies, disadvantages of capacitive sensors, such as susceptibility to interference and stray capacitance, have been continuously overcome. Capacitive grating displacement sensors and integrated capacitive sensors have also 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 promising development prospects.

DI SAVIOLI 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 axis of the applied load coincides with the force axis of the load cell to minimize the effects of inclined 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) 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 specified in its instructions. Although the load cell itself has 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.
