Oil water analyzer, capacitance moisture analyzer

The built-in capacitance sensor of the new generation oil-water analyzer LK-XB101-TF70LK-XB101TF70 uses the oil on the north side as the dielectric material. The capacitance signal is linearly related to the water content and temperature. Whether it is changes in the water content or temperature of the mixed liquid, it will cause changes in the dielectric constant. Change the product * to solve the problems of low measurement accuracy, false alarm signals, and zero drift caused by long-term use of oil-water signalers in previous on-site use. After testing, the temperature characteristics of the lifting device are linear. At different temperatures, the relationship between the sensor output and the oil temperature follows a linear equation, and the square value of the linear correlation coefficient reaches 0.999. The temperature compensation test of our company's products includes various temperature values ranging from 5 to 80 ° C. The same type of oil has different output frequencies at different temperatures, and the temperature compensation coefficient of a single sensor remains *. Therefore, measuring the degree of the sensor in the tested new oil at different temperatures can obtain the compensation coefficient and output frequency at a certain moisture content of 0 ° C.

The product accuracy reaches 0.25 precision (our company accepts on-site verification), and it is stable and reliable for a long time. To adapt to the usage environment of hydropower plants, this product has added analog output on the basis of digital quantity. At the same time, it is also possible to use the control motherboard to drag several sensor probes (Xiluodu uses this method).
