Abstract

Concentric bundle probe dapat dimanfaatkan untuk mendeteksi ketinggian air dengan berbasis pada sensor pergeseran. Mekanisme kerja sensor adalah mendeteksi pergeseran reflektor yang merekat pada membran akibat perubahan ketinggian zat cair. Pergeseran reflektor terdeteksi melalui perubahan intensitas cahaya pantulan dari reflektor yang masuk fiber optik penerima yang mengelilingi fiber optik pemancar cahaya. Penggunaan satu lapis membran dari bahan nitrile polymer dengan tebal 0,08 mm menghasilkan daerah kerja sensor sebesar 100 cm dengan resolusi sebesar 0,9 cm.DOI: https://doi.org/10.17977/um024v2i22017p048

Abstract

Detection of the concentration of rhodamine B in distilled water using a fiber coupler and fiber bundle as probes with a static position on the sample surface and not in direct contact with the sample was successfully carried out. The working mechanism of the sensor uses the principle of sample absorption of the light that passes through it. The concave mirror functions as a reflector and a sample container, allowing an undirect contact probe sensor with the sample. Both types of sensors show similar performance. The best detection is shown by sensors that use fiber bundles as probes. The resulting sensitivity and resolution are 2.1 mV/ppm and 0.29 ppm, respectively.DOI: 10.17977/um024v7i22022p127
