Ziraat Mühendisliği Uygulamalarında Kullanılabilecek Esneklik Sensörlerinin Tasarımı ve Testi
Esneklik sensörleri, farklı teknolojilerde kullanılan esnek malzemelerin bükülmeye karşı verdikleri tepkileri ölçmek için kullanılırlar. Kolayca temin edilebilir ve düşük maliyetli malzemelerle üretilebilirler. Kompaktlığı, hafifliği ve düşük güç tüketimi, bu sensörü şekillendirme veya bükme davranışındaki değişiklikleri izlemek için gereken tüm uygulamaların yanı sıra manifold tasarımları için ideal kılar. Bu çalışmada özel üretim, daha uzun ve düşük maliyetli bir esneklik sensör tasarımı için gerekli adımlar tartışılmıştır. Direnç seçiminin, sıcaklığa bağlılığın ve mümkün olan maksimum uzunluğun dikkate alınması gereken ana kriterler olduğu belirlenmiştir. En geniş sensor çıktı aralığını veren resizstansın maksimum 75 cm uzunluğundaki bir sensör için 100 Ω olduğu belirlenmiştir. Çalışmanın bir diğer önemli bulgusu, sıcaklık kompansasyonu gereksinimidir.
Design and Testing of Flexibility Sensors to be Used in Agricultural Engineering Applications
Flexibility sensors are used to measure bending response of flexible materials which are employed in different technologies. They can be produced with easily available and low-cost materials. Its compactness, lightness and low power consumption makes this sensor ideal for manifold as well as any applications needs to monitor changes in shape or bending behavior. In this paper essential steps needed to design a custom-made, longer and cost effective flex sensor are discussed. It was found that selection of resistor, temperature dependency, and maximum possible length are major criteria to be considered. The best resistor yields the widest range was determined to be 100 Ω with maximum length of 75 cm. Another important finding of the study was the need of temperature compensation.
