Question

Describe a total radiation pyrometer.


Solution

It consists of a concave mirror M made of copper and plated with nickel. The mirror has a small hole at the center at which an eyepiece E is fitted. A diaphragm D is placed at the focus of M; which has a hole to allow radiation to pass through it. A blackened metal strip S is placed behind D. To the other surface of S, one junction of a thermocouple TT is connected. The thermocouple is connected to a millivoltmeter. A screen R is used to protect the strip from direct radiation. The mirror can be adjusted for focus.
