Oil dielectric constant detector

1、 Product Introduction

In the lubrication and insulation oil management of industrial equipment, the dielectric constant, as a key electrical parameter reflecting the polarity, aging degree, and pollution status of oil products, is increasingly becoming an important indicator for rapid on-site evaluation of oil product quality. When lubricating oil or insulating oil undergoes oxidation, water infiltration, additive decomposition, or impurities are mixed in, its molecular polarity increases and the dielectric constant significantly increases. Therefore, by monitoring the changes in dielectric constant in real time, it is possible to effectively determine whether the oil has deteriorated, been contaminated, or is approaching the critical point of failure, especially suitable for applications such as transformer oil, hydraulic oil, gear oil, etc. that require high insulation or purity.

To meet the requirements of efficient, non-destructive, and low-cost on-site testing,Oil dielectric constant detectoremerge as the times require. This instrument is based on the principle of high-frequency capacitive sensing or resonant circuit. By placing the oil sample between high-precision measuring electrodes, it automatically measures its dielectric response at a specific frequency and outputs standardized dielectric constant values in combination with temperature compensation algorithm. The device usually integrates an ARM processor, high-sensitivity sensors, 7-inch touch screen, temperature control module, USB/Bluetooth interface, and built-in power supply. It is easy to operate, responds quickly, and only requires a small amount of oil sample to complete the test in 1-2 minutes.

Oil dielectric constant detectorNot only can it be used independently for oil quality screening, but it can also be linked with other parameters (such as viscosity, moisture, acid value) for analysis, to construct a multidimensional oil health assessment model. Widely used in the fields of power system (transformer oil monitoring), petrochemicals, metallurgy, wind power, rail transit, and large-scale industrial equipment operation and maintenance, it is an important technical means to achieve "oil replacement according to quality", early fault warning, and predictive maintenance, helping enterprises reduce operation and maintenance costs and improve equipment reliability and safety.

2、 Functional Features

High measurement accuracy: The measurement accuracy is highly consistent with large laboratory instruments and equipment, with built-in heating modules that provide accurate measurement of physical and chemical indicators of oil at standard temperatures of 40 ℃ and 100 ℃

2. Easy to operate: The touch screen and its operation prompts assist in completing the entire measurement process. With a Chinese interface, users only need to prepare an oil sample and follow the operation guide prompts to read out the results.
