III. Working Principle

The working principle of the surface tension tester is based on a high-frequency induction micro-displacement automatic balance measurement system. When the force acting on the platinum ring changes, the balance rod connected to the platinum ring produces displacement in the two eddy current probes. This displacement causes a change in the inductance generated in the two eddy current probes, leading to the differential transformer losing balance. As the input signal of the differential amplifier in the circuit also loses balance, it is amplified by the amplifier and outputs an electrical signal that varies with the change in force on the platinum ring. This signal is sent to a microprocessor for processing, and according to internationalGB6541The standard automatically calculates the actual tension of the tested sample.

By utilizing this advanced working principle, the interfacial tension tester can accurately and rapidly measure the surface tension of liquids and the interfacial tension between mineral oil and water, providing strong support for scientific research, education, and industrial production.
