Methods to Measure Moisture in Oil
The determination methods of moisture in oil are mainly divided into on-site determination method, laboratory determination method and online determination method.
On-site measurement methods , commonly used are visual inspection method , burst test method and calcium hydride test method .
Laboratory determination method: Solvent reflux method Fluorescent detection method Karl Fischer method
Online measurement method
Sensors can measure the temperature and relative saturated water content of petroleum products. There are many types of sensors, mainly moisture in oil sensors and optical sensors. As the water concentration increases or decreases, the capacitance of the moisture in oil sensor also changes accordingly. By converting the moisture content into the capacitance value, the moisture content in the oil is indirectly measured. The optical sensor converts the wavelength into moisture content by establishing a standard curve according to the change of the wavelength of light passing through the oil. The test results are expressed in percentages, and the polyimide capacitive humidity sensor and temperature sensor are used to realize the online detection of the trace water content in the oil, which can well reflect the trace water content in the transformer oil and can achieve the purpose of online detection.
Application of oil moisture sensor
In the operation of large mechanical equipment, the moisture in the oil poses a great threat to the normal operation of the equipment. The presence of moisture in the oil will destroy the oil film, cause additive failure, cause corrosion of metal parts, shorten the service life of the oil, and even cause unplanned shutdown of large machinery, resulting in serious safety accidents and economic losses. For generator sets and transformers, moisture will destroy the insulating properties of oil, posing a threat to the safety of power equipment and personnel.
PPM-HLW-2A moisture in oil transmitter is widely used in large-scale continuous operation equipment and heavy machinery equipment. Real-time monitoring of the moisture content of lubricating oil and hydraulic oil can be realized, and the data can be directly uploaded to the oil monitoring system, which plays an irreplaceable role in scientifically maintaining the normal operation of these key equipment.
Common oil moisture transmitter
PPM-HLW-2A moisture in oil transmitter adopts a unique moisture sensing probe, which can quickly capture the electrical characteristic changes of the oil-water mixture in lubricating oil and hydraulic oil in real time, and obtain the moisture content in the oil through an optimized algorithm. This oil moisture transmitter is an oil micro-water transmitter, which can accurately measure the water content of 0~1000ppm, and the resolution can reach 0.1%. Suitable for common mineral oils, synthetic and semi-synthetic lubricating oils, hydraulic oils and transformer oils. Please refer to the link for specific parameters.
