एडी करंट प्रॉक्सिमिटी सेन्सर्स

 

  • एडी विद्युतप्रवाह हा एक गोलाकार प्रवाह आहे जो बदलत्या चुंबकीय क्षेत्रात ठेवल्यावर वाहकाद्वारे प्रेरित होतो.
  • धातूसारख्या चुंबकीय प्रवाहकीय सामग्रीची उपस्थिती शोधण्यासाठी एडी विद्युतप्रवाह सेन्सर्सचा वापर केला जातो.
  • एडी करंट सेन्सर प्रेरक एडी-विद्युतप्रवाह तत्त्वावर आधारित कार्य करतो.
  • जेव्हा सेन्सिंग कॉइलला पर्यायी प्रवाह पुरवला जातो, तेव्हा ते कॉइलभोवती चुंबकीय क्षेत्र तयार करते.
  • जर या क्षेत्रात विद्युतीय वाहक सामग्री ठेवली असेल, तर फॅराडेच्या प्रेरण कायद्यानुसार एडी विद्युतप्रवाह क्षेत्र प्रेरित केले जाते.
  • जेव्हा वस्तू गतिमान असते तेव्हा ते कॉइलच्या संरोधात बदल घडवून आणते, जे सेन्सर आणि लक्ष्य यांच्यातील अंतराच्या बदलाच्या समानुपाती असते.
