Abstract:

Three commercially available densiometers, were evaluated. Measurements were made at 425, 900, 1300, 2850, and 5300 mc. The results of the tests show that none of the densiometers tested is suitable in all respects. The error at UHF is in the order of 6db, but is in the direction to insure personnel safety. At 900 mc the error is in the order of 1.8db, but again in the conservative direction. When horns are used as the pick-up antenna, the correlation is within 1db. Continuous coverage could be obtained by using more horns with properly chosen attenuators to compensate for gain variation, if necessary. Author
