Integrated oil property sensor measuring viscosity, density, dielectric constant and temperature at one point with ±5 kg/m³ density accuracy for precise oil-condition assessment.
The 4-in-1 Oil Property Sensor integrates viscosity, density, dielectric constant and temperature measurement in a single device. Imported high-quality probes help ensure reliable and high-accuracy measurements, and the integrated multi-parameter design enables synchronized sensing of key oil characteristics at one installation point, with density measurement accuracy up to ±5 kg/m³.
The condition of lubricating and hydraulic oil determines the health of the machinery it protects. The 4-in-1 Oil Property Sensor approaches oil-condition monitoring comprehensively, integrating four critical measurements — viscosity, density, dielectric constant and temperature — into one device. By sensing these parameters at a single installation point, the sensor provides a synchronized picture of oil condition rather than piecemeal readings from multiple instruments.
Viscosity is the fundamental indicator of oil degradation and contamination; density helps detect the presence of incompatible fluids or dilution; dielectric constant responds to oxidation, water ingress and particle contamination; and temperature contextualizes all of these readings, since oil properties vary strongly with temperature. Having all four parameters from the same probe at the same moment removes the ambiguity that arises when measurements are taken at different times, locations and temperatures.
The sensor's imported high-quality probes support reliable, high-accuracy measurement in demanding service. Density measurement accuracy can reach ±5 kg/m³, providing confidence for oil-condition assessment decisions. The single-installation-point design also simplifies retrofit: rather than plumbing multiple sensors into an oil line or reservoir, operators install one device and immediately gain a full four-parameter picture of oil condition.
