EFFECT OF SOLUTION TEMPERATURE ON VOLTAGE RANGE AND SENSITIVITY OF LOWTEMPERATURE SENSOR CU/NI RESULTS FROM ELECTROPLATING ASSISTED BY PARALLEL MAGNETIC FIELDS

This study aims to identify the effect of solution temperature aided by parallel magnetic fields on the sensitivity and voltage range of the Cu/Ni sensor as a lowtemperature sensor. Solution temperature was varied from 30°C-70°C. The results of data analysis showed that the highest sensitivity is a sensor which is deposited at a temperature of 60°C with a sensitivity level (0.118 ± 0.004) mV/°C with R2= 0.98 and sensor which has the lowest sensitivity sensor with the deposition temperature of 30°C is (0.0004 ± 0.007) mV/°C with R2= 0.96. In contrast to the sensitivity, the highest voltage range is 39.67 mV owned by the sensor which is deposited at 30°C and 60°C while the lowest voltage range is 32.04 mV as a result of the deposition temperature of 40°C.
