EMISSIVITY MEASUREMENT APPARATUS

Description

The present Set-up is designed tomeasure the emissivity of test plate.

The test plate comprises of a micaheater sandwiched between two circular plates.

Black plate is identical with testplate, but its surface is blackened.

As all the physical properties,dimension and temperature are equal heat losses from both plates will be sameexcept radiation loss.

Hence the input difference will bedue to difference in emissivity.

Both plates are supported onindividual brackets in a enclosure with one side glass to ensure steadyatmospheric conditions.

Temperature Sensors are provided tomeasure the temperature of each plate and surrounding.

Electric Supply is given to heatersthrough separate variacs so that temperatures of both can be kept equal and isme asured with Digital Voltmeter and Digital Ammeter.
