तापयुग्म:
- तापयुग्म हे तापमान मोजण्यासाठी वापरले जाणारे सेन्सर आहे.
- साधारणपणे, 1400° पर्यंतचे तापमान या उपकरणाद्वारे मोजले जाते.
- इंजिनच्या आत तापमान मोजण्यासाठी तापयुग्म सामान्यतः निकेल आणि क्रोमियमचे बनलेले असते.
- यात वेगवेगळ्या धातूपासून बनवलेल्या दोन वायर लेग असतात.
- वायरचे लेग एका टोकाला एकत्र जोडले जातात, जंक्शन तयार करतात.
- हे जंक्शन आहे जेथे तापमान मोजले जाते.
- जेव्हा जंक्शन तापमानात बदल अनुभवतो तेव्हा व्होल्टता तयार होते.
- त्यानंतर तापमान मोजण्यासाठी तापुयुग्म संदर्भ सारणी वापरून व्होल्टताचा अर्थ लावला जाऊ शकतो.
- हे सीबेक प्रभावाच्या तत्त्वावर कार्य करते जे सांगते की दोन भिन्न विद्युत वाहकामधील तापमानातील फरक त्यांच्यामध्ये व्होल्टता फरक निर्माण करतो.
- हा संभाव्य फरक तापमान मोजण्यासाठी वापरला जातो.

- प्रकार E (क्रोमेल - कॉन्स्टंटन)
