Errors in thermocouple temperature measurement.

Thermocouple Temperature Measurement Errors with Solutions

Thermocouples rank among the most favored instruments for industrial temperature measurements due to their adaptability, accuracy, and user-friendliness. But thermocouple temperature measurement errors can still arise. Thermocouples tend to serve as quite robust temperature gauges that are suitable for numerous industrial & scientific tasks. Their affordability relative to their measurement technologies stems from their capability to measure a broad temperature spectrum that ranges from as low as –200°C to as high as +1250°C (–328° to +2282°F).

Thermocouple Operating Principle

Operating on the principle of measuring temperature differentials instead of absolute values, thermocouples contain two wires made from distinct metals that are joined at the tip, forming a measuring junction. The wires connect to a body of known temperature, which is termed the reference junction, at the opposite end. By detecting the voltage disparity between these 2 junctions, facilitated by the Seebeck effect, thermocouples tend to convert this voltage into temperature units, which are then displayed/transmitted for remote monitoring.

6 Causes for Thermocouple Temperature Measurement Errors with Solutions

Sometimes, thermocouples are susceptible to errors in temperature measurements owing to various factors. Below are the 6 most prevalent reasons for thermocouple inaccuracies, along with their suggested remedies:

1.Wrong Selection of Thermocouple Type on the Transmitter:

  • Errors tend to arise if a wrong thermocouple type has been selected while configuring the settings on the transmitter during the process of installation. With many thermocouple types available around, such as K, N, E, J, T, R, S, & B, each having its own set of distinct characteristics, confusion is obvious.
    • Solution: You must verify the colour of the thermocouple jacket that is typically color-coded by its type, and then adjust your settings on the transmitter as per that only.

2. Issues Related to the Thermocouple’s Extension Wire:

  • Reversing the polarity of the thermocouple’s lead wires could possibly lead to temperature measurement discrepancies that are usually equivalent to temperature differences between the 2 ends of the leads. Such a problem is compounded by the unconventional coloration of thermocouple cables, where the red wire often carries the negative signal.
    • Solution: Double-check your connections and also try to swap the thermocouple lead wires.

3. Inherent Variations in the Alloys:

  • Minor discrepancies in alloy percentages at the time of manufacturing the product can result in unavoidable errors in the accuracy of thermocouples.
    • Solution: Choose the best thermocouples with special-limit wires. Manufacturers construct them to the highest tolerances to enhance their accuracy.

4. Temperature Fluctuations Occurring Around the Reference Junction Connection:

  • Ambient temperature fluctuations occurring around the reference junction can affect the accuracy of temperature readings. These can also skew temperature readings owing to the differential measurement principle of the thermocouples.
    • Solution: Ensure that no cooling/heating sources are lying near the reference junction. Also, consider insulating these junctions to help them shield from extreme temperatures.

5. Multiple Grounding Locations for Thermocouples:

  • Grounding a thermocouple device at more than 1 particular location can create a “ground loop.” This causes current to flow through the thermocouple between different ground points. This can possibly cause electromagnetic field generation & related interference issues. These also tend to affect temperature measurement accuracy.
    • Solution: Ground any one of them; either the transmitter or the controller/recorder, but not both. You must utilize transmitters with internal isolation between input/output, and ground or employ loop isolators for preventing ground loop formation.

6. Aging:

  • Thermocouples tend to experience measurement drift with prolonged usage, which can lead to inaccuracies over time. Some factors are maximum temperature exposure, frequency of cyclic measurements, and the number of cycles. They tend to impact the metallurgy. This results in gradual drift, typically downwards, in temperature measurements.
    • Solution: Replace thermocouples periodically based on use, as drift can’t be predicted. Temperature errors of 10-20°F tend to be common indicators for replacement.

अनुचित या अपर्याप्त इन्सुलेशन

यदि थर्मोकपल तारों को ठीक से इंसुलेटेड नहीं किया गया है, तो वे क्षतिग्रस्त भी हो सकते हैं। इससे तार ढीले हो सकते हैं या मापने वाले उपकरण से कनेक्शन ढीला हो सकता है, जिसके परिणामस्वरूप तापमान रीडिंग गलत हो सकती है।

अंशांकन की समस्याएँ

यदि माप उपकरण ठीक से अंशांकित नहीं है, तो रीडिंग गलत हो सकती है। ऐसी स्थिति में थर्मोकपल को बदलने की आवश्यकता होती है। आपको ऐसे किसी भी मुद्दे को ठीक करने के लिए अंशांकन की जांच और सत्यापन करने के लिए समयसमय पर थर्मोकपल डिवाइस का मूल्यांकन करने के लिए एक विशेषज्ञ की आवश्यकता हो सकती है।

ख़राब इंस्टालेशन

थर्मोकपल ख़राब इंस्टालेशन के कारण भी विफल हो सकते हैं। यदि तार ठीक से जुड़े नहीं हैं या परिचालन की स्थिति थर्मोकपल डिवाइस के साथ संगत नहीं है, तो यह अंततः थर्मोकपल डिवाइस की विफलता का कारण बनेगा।

थर्मोकपल की विफलता के अंतर्निहित कारण

थर्मोकपल संवेदनशील उपकरण हैं जिनका उपयोग तापमान मापने के लिए किया जाता है। वे दो अलगअलग धातुओं से बने होते हैं जो मापने वाले जंक्शन पर एक साथ जुड़े होते हैं। दोनों धातुएँ एक वोल्टेज मीटर या रिकॉर्डर से जुड़ी होती हैं। जब मापने वाले जंक्शन पर तापमान बदलता है, तो थर्मोकपल द्वारा उत्पन्न वोल्टेज भी बदल जाता है! आईये थर्मोकपल की विफलता के बारे में जाने।

थर्मोकपल की विफलता मोड

कुछ पर्यावरणीय और परिचालन कारक हैं, जो एक निश्चित अवधि से परे थर्मोकपल विफलता का कारण बन सकते हैं; इस प्रकार डिवाइस का उपयोग करके किए गए किसी भी तापमान माप की दक्षता और सटीकता खराब हो गई। इसलिए, विभिन्न थर्मोकपल विफलता मोड को स्वीकार करना और उन पर विचार करना बेहद महत्वपूर्ण है, जो समय के साथ तापमान को मापने में इसकी सटीकता पर प्रतिकूल प्रभाव डाल सकते हैं, जिसके परिणामस्वरूप डिवाइस के माध्यम से गलत माप हो सकते हैं। यहां कुछ सबसे सामान्य थर्मोकपल विफलता मोड दिए गए हैं जो थर्मोकपल के विफल होने का कारण बन सकते हैं:

समय के साथ ऑक्सीकरण के कारण संक्षारण

सबसे पहले ऑक्सीकरण के कारण संक्षारण होता है। समय के साथ, थर्मोकपल की उजागर धातु ऑक्सीकरण और संक्षारण कर सकती है, जिससे थर्मोकपल विफल हो सकता है। ऐसा तब होता है जब थर्मोकपल में धातु ऑक्सीजन और नमी के संपर्क में आती है, जिससे इसका संक्षारण होता है।

शारीरिक क्षति

थर्मोकपल को शारीरिक क्षति भी विफलता का कारण बन सकती है। यदि थर्मोकपल किसी भी तरह से मुड़ा हुआ या क्षतिग्रस्त है, तो इससे थर्मोकपल टूट सकता है या विफल हो सकता है। ऐसा तब हो सकता है जब थर्मोकपल क्षतिग्रस्त हो या टकरा जाए या गिर जाए, या यदि यह ऐसे क्षेत्र में स्थापित हो जहां बहुत अधिक कंपन हो।

धातु घिसपिस

समय के साथ, थर्मोकपल की उजागर धातु घिसपिस हो सकती है, जिससे अंततः थर्मोकपल टूट सकता है या विफल हो सकता है। ऐसा तब होता है जब थर्मोकपल में धातु पर बारबार जोर दिया जाता है या उसे मोड़ा जाता है, जिससे वह अंततः टूट जाता है।

वेल्डिंग समस्या

यदि थर्मोकपल को अनुचित तरीके से वेल्ड किया गया है, तो इससे थर्मोकपल विफल हो सकता है। अनुचित वेल्डिंग के कारण थर्मोकपल टूट सकता है या वेल्ड अलग हो सकता है, जिससे थर्मोकपल विफल हो सकता है। यदि वेल्ड ठीक से नहीं किया गया है, तो यह थर्मोकपल में एक कमजोर स्थान बना सकता है जो सही ढंग से काम नहीं करेगा।

गलत थर्मोकपल का उपयोग करना

थर्मोकपल विभिन्न धातुओं से बने होते हैं, और प्रत्येक की एक अलग तापमान सीमा होती है जिसे वह झेल सकता है। यदि थर्मोकपल का उपयोग उसके तापमान सीमा के बाहर किया जाता है, तो यह विफल हो सकता है। इसलिए, गलत थर्मोकपल का उपयोग करने से भी समस्याएँ हो सकती हैं।

अपर्याप्त इन्सुलेशन

यदि इन्सुलेशन पर्याप्त नहीं है, तो यह गर्मी को बाहर निकलने की अनुमति दे सकता है, जो अंततः थर्मोकपल के विफल होने का कारण बन सकता है।

अंशांकन समस्या

यदि थर्मोकपल को ठीक से अंशांकित नहीं किया गया है, तो यह सही ढंग से काम नहीं करेगा क्योंकि यह तापमान को सटीक रूप से मापने में सक्षम नहीं होगा, जिससे विफलता हो सकती है।

खराब स्थापना

यदि थर्मोकपल ठीक से स्थापित नहीं है, तो यह सही ढंग से काम नहीं करेगा क्योंकि यह ढीला हो सकता है और अंततः गिर सकता है, जिससे यह विफल हो सकता है।
