Building a Sensor Circuit to Measure High Temperatures

Click For Summary
SUMMARY

The discussion focuses on building a sensor circuit capable of measuring temperatures up to 2000°C. Lakmal is exploring the use of infrared (IR) sensors but finds them to be prohibitively expensive. The inquiry centers on methods to suppress incoming IR radiation and redirect it to a sensor with a lower temperature sensing range, specifically referencing thermopiles as a potential solution.

PREREQUISITES
  • Understanding of infrared (IR) sensor technology
  • Familiarity with thermopile sensors
  • Basic knowledge of circuit design
  • Experience with temperature measurement techniques
NEXT STEPS
  • Research methods for IR radiation suppression techniques
  • Explore alternative low-cost IR sensors suitable for high-temperature applications
  • Learn about thermopile sensor specifications and applications
  • Investigate circuit design principles for temperature measurement systems
USEFUL FOR

Electronics engineers, hobbyists building temperature measurement devices, and researchers focused on high-temperature sensor applications.

Hi,

I have to build a sensor circuit to measure temperatures up to 2000°C. I searched for an IR sensor for this and it seems they are very costly.

Is there a way to suppress the incoming IR radiation from the source and direct it to a sensor having lower temperature sensing ranges?

I would appreciate if someone can be of help.

Regards,
/Lakmal
