| Popis: | This study aims to test the temperature sensor that will be used in the biochar production furnace. Temperature testing is carried out to determine the ability of the sensor to respond to temperature changes that will be applied to the furnace. The sensors used in this system are the K-type thermocouple and the MAX6675 module. Testing is done by forming a control system. The system will be installed in the furnace by providing heating with fire in the furnace. The result of the maximum temperature was 574.25 °C at 575 seconds of heating for 1110 seconds. The test of corelation between the sensor output voltage to temperature when the temperature is raised from the beginning to the maximum, the sensor sensitivity is obtained at 5.1762 mV / °C and the slope of the graph is close to 1. Testing the relationship of the sensor output voltage to temperature when the temperature is lowered from the maximum point, the sensor sensitivity is obtained at 4.878 mV / °C and an offset voltage of 25 mV. The voltage-to-time correlation of the two tests is close to the value of 1, which means that the sensor linearity is very good so that it can be used as a temperature measurement tool. |
