Building a Sensor Circuit to Measure High Temperatures

AI Thread Summary
Building a sensor circuit to measure temperatures up to 2000°C can be challenging due to the high cost of IR sensors. A potential solution involves suppressing incoming IR radiation and directing it to a sensor with a lower temperature range. This approach may allow for more affordable components while still achieving accurate temperature measurements. Suggestions and insights on effective methods for radiation suppression and sensor selection are sought. The discussion emphasizes the need for practical solutions in high-temperature measurement 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,

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
