Black Wall Guard Cavity Connector, For HDPE

KM Green Vision is the best black wall guard cavity connector in India. A black body cavity radiometer is provided by a radiation-receiving isothermal body having a short hollow cylinder with a hollow cone at one end. The cylinder is spun down at the other end to a smaller hollow cylinder of short length to form a radiation cavity having an aperture.

A thermal guard surrounds the cavity, except over the aperture. The annular wall of the guard around the short cylindrical extension of the cavity is provided with an internally blackened groove which functions as an annular radiation trap for radiation from the internal surface of the guard and the external surface of the cavity.

Glass rods or fibres maintain a thin annular space between the guard and the cylindrical extension of the cavity. A guard temperature sensing coil is provided on a hollow cylinder disposed in space between the guard and the cavity. The hollow cylinder is thermally connected to the guard by a flange. A heating and the temperature-sensing coil is wound directly on the main cylindrical portion of the cavity.

A voltage is applied across the latter coil in sufficient amplitude to maintain the temperature of the latter coil equal to the temperature of the guard sensing coil. The magnitude of that voltage is a measure of radiation into the cavity through the aperture thereof. We are the best black wall guard cavity connector, manufacturer.
