प्रतिकार तापमान शोधक (RTD)

  • प्रतिकार तापमान शोधक हे एक इलेक्ट्रॉनिक यंत्र आहे जे विद्युत वायरचा प्रतिकार मोजून तापमान निर्धारित करण्यासाठी वापरले जाते.
  • या वायरला तापमान सेन्सर असे संबोधले जाते.
  • उच्च अचूकतेसह तापमान मोजण्यासाठी, RTD चा वापर केला जातो कारण त्यामध्ये तापमानाच्या विस्तृत श्रेणीवर चांगली रेखीय वैशिष्ट्ये आहेत.
    तांबे, निकेल आणि प्लॅटिनम हे RTDसाठी मोठ्या प्रमाणावर वापरले जातात.
  • RTD मध्ये प्रतिरोधक तापमान गुणांक असतो.
  • म्हणून, तापमान वाढीसह RTD प्रतिकार वाढतो.
