Investigations of Complimentary Split Ring Resonator (CSSR) as Viscometer for Engine Oils

Abstrak

Engine oils or lubricating oils are used to reduce friction and wear by interposing a film of material between rubbing surfaces. Meanwhile, a viscometer is an instrument used to identify the resistance of a fluid to shear or tensile stress. Therefore, the material property of viscosity is important in analyzing many engineering situations, specifically in the automation industries that utilizing engine oils that are associated with the functionality or performance of vehicles and machinery. Hence, this work aims to design and fabricate a Complementary Split Ring Resonator (CSRR) sensor to measure the viscosity of different types of engine oils by evaluating their dielectric properties. The CSRR is used to measure the dielectric property of engine oils and establish the relationship between viscosity and dielectric properties. The findings show the lowest viscosity oil produces the lowest dielectric constant values and the highest viscosity oil has the highest dielectric constant values. These results gained enable the possibility of distinguishing the oil engine oils based on their dielectric properties. Therefore, future works on a more comprehensive study can be conducted by purchasing various engine oils that are available in the Malaysian market.
