Thermal Radiation: Measurement & Conversion Help

AI Thread Summary
The discussion centers on using a Radiation Pyrometer, specifically the Heitronics KT19.XX Series, to measure temperature and radiation. The user is struggling to convert voltage measurements into radiation values, particularly when the target is not a black body, such as a wall or vegetation. There is uncertainty regarding the appropriate emission grade to set and whether Planck's law can still be applied in this context. Participants suggest contacting the manufacturer for specific guidance on these issues. Understanding the application of Planck's law for non-black body targets is crucial for accurate radiation measurements.

hallo to all,

i use a Radiation Pyrometer to measure temperature and Radiation
Trough a datalogger i get those measurements in Volt
i am able to convert the Volt back in the temperature but in Radiation it is more difficult
i found the Plancksche function, but i do not really understand that

can anybody help me?
thanks in advance!

best regards

Describe your pyrometer.
 
If the target is a black body, then the radiation only depends on the temperature and surface area. If you know the temperature, then plug it into Planck's law to get the brightness (as a function of wavelength or frequency).
 
It is a Pyrometer from Heitronics, KT19.XX Series

My target is not a black Body, for testing i measure now in the Office the door/wall. Later it will be used to measure Vegetation.
I´m also not sure which emissiongrade i should set. Can i use Planck`s law, although i measure not a black Body? Is the function the same?

Thank you guys so much!

Best regards

I think you should email the manufacturer and ask about this.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
