Embodiments of a probe for measuring an oil viscosity are provided. In one embodiment, the probe includes a housing, a magnetoelastic ribbon, an electromagnetic coil, a temperature sensor and an electrical board. The housing is mounted to an oil containing member. The magnetoelastic ribbon is fixed to an inside of the housing through a first insert member at one end and is at least partially immersed in the oil at an opposite end. The electromagnetic coil is disposed in the housing to surround the magnetoelastic ribbon. The temperature sensor is mounted to the housing for measuring a temperature of the oil. The electrical board is electrically connected to the electromagnetic coil and the temperature sensor.

Method and apparatus for measuring oil viscosity

Various embodiments of an oil monitoring apparatus are provided. In one embodiment, an oil monitoring apparatus includes a probe and an analyzing module in-line connected to the probe. The probe includes: a first sensor for measuring respective optical intensities of a light passing through the oil at respective red, green and blue wavelength ranges; a second sensor for measuring a water content; and a third sensor for measuring a temperature of the oil. The analyzing module calculates and monitors chemical deterioration of the oil, total contamination of the oil, a relative saturation of the oil by water and temperature of the oil based on the output signals of the first and third sensors. The oil monitoring apparatus monitors various parameters relating to the deterioration of the oil and to the physical properties of the oil.

Integrated in-line oil monitoring apparatus

A measurement apparatus determines contaminant level of oil by qualitatively measuring the light intensity after the light has transmitted through an oil sample. The apparatus comprises light emitting means for generating light to be provided to the oil sample, a container for storing the oil sample, the container being displaced from the light emitting means by a predetermined distance, light receiving means for detecting the intensity of light transmitted through the oil sample, the receiving means being displaced from the container by a predetermined distance, first light conveyance means for conveying the light generated by the light emitting means as coherent light to the oil sample, second light conveyance means for conveying the light transmitted through the oil sample to the light receiving means, wherein the characteristics of the light emitting means and the light receiving means are controlled so that they do not vary depending on the temperature of the oil sample.
