Optimasi Pemanfaatan Sensor Kapasitif Berbasis Perubahan Fasa Untuk Mengukur Kadar Air Dalam Biodiesel
Main Article Content
Abstract
Optimasi dilakukan pada sistem sensor kapasitif dengan mengkondisikan sinyal pada tegangan saat proses perubahan kapasitansi ke konversi fasa, kesimetrisan peak-to-peak gelombang kotak, dan tegangan baseline sebelum nilai output dikeluarkan melalui gerbang XOR (Exclusive-OR) dengan osiloskop. Sinyal kotak hasil konversi gerbang XOR yang menunjukkan nilai fasa diteruskan ke komputer, dan ini menunjukkan keberadaan air dalam biodiesel. Selanjutnya kondisi pengukuran yang telah optimal dipakai untuk percobaan mengukur kadar air dalam biodiesel. Hasilnya sistem sensor yang telah dioptimasi mampu membaca kadar air dalam biodiesel pada rentang konsentrasi rendah.
