Introduction: The WKT-ZL6 automatic tensiometer is suitable for GB/T6541 standard, based on the ring method (platinum ring method), to measure the surface tension of various liquids (liquid-gas phase interface) and the interfacial tension of liquids (liquid-liquid phase interface). This method has the advantages of simple operation and high accuracy and is widely used. Widely used in electric power, petroleum, chemical, pharmaceutical, food, teaching and other industries. The principle of Veken Meituo WKT-ZL6 automatic tension measuring instrument: The structure of this instrument is mainly composed of torsion wire, differential transformer, platinum ring and lifting part. , Gears and trays drive the glassware containing the liquid to be tested to descend. At this time, the ink between the platinum ring and the liquid to be tested is elongated, so that the platinum ring is subjected to a downward force, and the torsion wire is twisted by the lever arm. , the magnetic core of the differential transformer rises with the fall of the platinum ring, so that the coil of the differential transformer induces a certain voltage value, so that the deformation of the stretched film is converted into a voltage, which is converted into a corresponding tension after processing by a microcomputer value is displayed automatically. As the film is gradually elongated, the tension value gradually increases until the film is broken, and the maximum value is recorded as the measured tension value P of the liquid, and then multiplied by the correction factor F of the liquid to obtain the actual tension value V of the liquid, That is, V=P•F, the correction factor F depends on the measured tension value P, the liquid density, the radius of the platinum wire and the radius of the platinum ring. Because the machine is controlled by a computer, the anti-interference of the instrument is increased in terms of software compilation and hardware design. During zero adjustment, electric zero adjustment is adopted, so that the magnetic core of the differential transformer can be zero adjusted as long as it is in a stable state within the zero adjustment range, which is very convenient and reliable to use. Features: 1. Multi-point calibration at equal intervals is adopted, which greatly improves the measurement accuracy and ensures the reliability of the measurement results. 2. Just enter the temperature value, and the temperature compensation can be automatically performed, which is extremely convenient to use. 3. Equipped with a standard RC232 interface, which can be connected to a computer for easy processing of test data 4. It can realize full Chinese/full English interface display (optional) 5. Establish mg=f(ad-result) function, and use multi-point calibration at equal intervals to ensure measurement accuracy 6. Clock function, power-down storage function 7. 240×128 dot matrix LCD screen, no key buttons, with screen protection function.
