Advanced Micro-Moisture Sensor for Lubricating & Hydraulic Oil – GAOTek

Description Overview Monitoring the micro-moisture of lubricating oil and hydraulic oil in large-scale continuous operation equipment, heavy machinery equipment and other equipment has an irreplaceable role in ensuring the normal operation of these key equipment. Because the presence of moisture will damage the oil film, cause the failure of additives, cause corrosion of metal parts, shorten the oil service life, and even cause an unplanned shutdown of large machinery, causing serious safety accidents and economic losses. For generator sets and transformers, moisture will destroy the oil’s insulating properties and threaten the safety of power equipment and personnel. The GAOTek-MAM-418 micro-moisture sensor can capture the change of electrical characteristics of the oil-water mixture in real-time, compensate the data through a high-precision temperature probe, and obtain the moisture content in oil through an optimization algorithm.   Features Continuous and Rapid Water Activity Detection Accurate Micro-Moisture Measurement Stable Long-Term Operation in Harsh Environments Compact Structure with Easy System Integration High Oil and Pressure Resistance Supports Multi-Mode Signal Output   Application Lubricating Oil Monitoring in Heavy Machinery Hydraulic Oil Condition Monitoring Transformer and Power Equipment Protection Industrial Equipment Moisture Detection Preventive Maintenance for Large-Scale Machinery Real-Time Oil Quality Assessment   Technical Specifications Specification Details Temperature -40 – 120 ℃, ±0.3℃ (at 25℃) Water Activity (aw) 0~1 aw, ±0.02 aw (0～0.6), ±0.03 aw (0.6～0.9), ±0.04 aw (0.9～1) Moisture Content (ppm) 0~5000 ppm, ±10% Working Voltage DC12～32V (RS485), DC20～32V (4-20mA) Working Current ＜20mA (RS485), ＜40mA (4-20mA) Working Temperature -40℃ ~ 85℃ Liquid Temperature -40℃ ~ 120℃ Storage Temperature -40℃ ~ 85℃ Detect Probe Allowable Pressure ≤ 15 bars Detect Probe Allowable Flow Rate ≤ 0.3 m/s IP Rate IP66 Detect Probe Material Stainless Steel 316 Threaded Interface G3/4 Electronic Interface M8*1, 6 Core Cable Connector 6 core, 2 meters length, 24AWG Weight 136g Applicable Oil Commonly used mineral oil, synthetic and semi-synthetic lubricating oil, hydraulic oil, transformer oil, etc.
