Analysis effect of temperature changes on measurement of oil viscosity based on plastic optical fibres sensor and microcontroller

Abstract

Testing of sensor based on plastic optical fiber can be applied to analyze the effect of temperature changes on the measurement of oil viscosity. This measurement uses gamma configuration at length of 3 cm peel on a plastic optical fiber sensor with cladding and without cladding. Testing of sensor on measurement of oil viscosity is using a microcontroller to determine the effect of temperature on the sensor output voltage. The output voltage of the differential amplifier in the form of an analog signal converted to a digital signal by the microcontroller and displayed on the computer. The output voltage increases with the increase of temperature changes occurring in the oil sample. The best results were obtained on sensor without cladding with the value 4.85 mV/°C. Measurement of the effect of temperature changes on oil viscosity based on plastic optical fiber sensor has advantages such as simple measurement system, low cost, easy fabrication and can be connected to computer.
