PNÖMATİK SENSÖRLER TP101 © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 1 / 91 Sensörlerin sınıflandırılması Sensörler: Temaslı • Temassız (proximity sensors) Olarak sınıflandırılırlar. Sanayide temassız olanlar daha çok kullanılırlar • © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 2 / 91 Limit Süviçler Temaslı sensörlerdir. Çıkış sinyali vermeleri için ikazlanmaları gerekir © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 3 / 91 Sensörler Optik-Hüzmeli Endüktif Optik - yansımalı Manyetik Optik Difüzer Endüktif manyetik © Festo Didactic – Training and Consulting Kapasitif Sembol Sensors 17.10.03 No. 4 / 91 İndüktif Sensör © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 5 / 91 indüktif Sensör Yüksek frekanslı manyetik saha (300 to 800 kHz) Aktif yüzey Yankı kangalı LED Bağlantı kablosu © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 6 / 91 Endüktif sensör Her türlü iletken metali tespit ederler Çeliği belli bir mesafeden tespit eder. Performansı : • Ortam sıcaklığı • Hedef materyali •Hedef ölçülerinden etkilenebilir. © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 7 / 91 Manyetik Temassız sensör Nitrojen dolu cam tüp © Festo Didactic – Training and Consulting LED Reed kontakları Sensors 17.10.03 No. 8 / 91 Reed switch © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 9 / 91 Reed switch 24v © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 15 / 91 Reed switch 24v © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 16 / 91 Reed switch Diğer manyetik alanlardan uzak tutulmalıdır Orta konum için yerleştirilmiş ise yaklaşım yönüne göre algılama mesafesi değişebilir. Reed kontakların yanmaması için maksimum akım limitlenmelidir. © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 17 / 91 İndüktif Manyetik Sensör Bağlantı kablosu © Festo Didactic – Training and Consulting Algı bobini Yüksek frekanslı manyetik alan Sensors LED 17.10.03 No. 18 / 91 Inductive magnetic sensor © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 22 / 91 Inductive magnetic sensor © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 24 / 91 İndüktif manyetik sensör Sadece manyetik alanları teşhis eder Diğer manyetik alanların etki sahasından uzak olmalıdır Yüksek frekans - 1kHz © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 25 / 91 Kapasitif Sensör Alandaki kapasitif değişikliği saptar Elektrostatik yüzey Aktif yüzey Aktif elektrod Arz elektrodu LED Ayar vidası Bağlantı kablosu © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 26 / 91 Capacitive sensor © Festo Didactic – Training and Consulting Target Sensors 17.10.03 No. 27 / 91 Capacitive sensor © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 28 / 91 Capacitive sensor © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 29 / 91 Capacitive sensor © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 30 / 91 Capacitive sensor Detects any material denser than air (as long as there is enough of it) Can be adjusted for sensitivity Can be affected by dusty environments © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 31 / 91 Capacitive sensor Sensor is adjusted so that it does not ‘see’ the wall of the vessel. © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 32 / 91 Capacitive sensor As the level rises the fluid affects the sensor field. © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 33 / 91 Capacitive sensor Until the sensor switches. © Festo Didactic – Training and Consulting Sensors 17.10.03 No. 34 / 91 Sensör sembolleri İndüktif Kapasitif + 18 to 30 Volts DC.
