Abstract

Automatic grading of oil palm fresh fruit bunch is desired. In this study, a capacitive sensing system was designed and developed for the purpose of grading oil palm fresh fruit bunch. In this method, oil palm fresh fruit bunch placed between capacitive plates as a dielectric material and then measure the resulting capacitance voltage. Experiments were carried out using oil palm bunches of Tenera variety. Ripe and unripe mature bunches tested with 100 kHz sinusoidal frequencies. Correlation of capacitive response observed to be linear to bunch weight and negative linear to bunch ripeness. This result suggest that this method be explored for automatic grading of oil palm fresh fruit bunch.

油棕鲜果串成熟度评定电容式传感器的设计
油棕鲜果串自动分级。本研究设计并开发了一种用于油棕鲜果串分级的电容式传感系统。在该方法中,将油棕鲜果束置于电容板之间作为介电材料,然后测量所得电容电压。实验以Tenera品种油棕为原料。成熟和未成熟的成熟束测试100 kHz正弦频率。电容性响应与束重呈线性关系,与束成熟度呈负线性关系。结果表明,该方法可用于油棕鲜果串的自动分级。
