PRODUCTION ENGINEERING MEASURE FOR RUGGEDIZED TAUT BAND SUSPENSION PANEL METERS PER SIGNAL CORPS TECHNICAL REQUIREMENTS SCS-43A
Abstract
Significant progress was made in obtaining the required performance for the 2-1/2 inch 100 degree instruments after subjection to vibration, tumbling and shock tests. The problem of ribbon breakage during tests was solved for ribbon sizes suitable for application in instruments having a full scale sensitivity of 20 micro-AMPERES. The electrical test results of the instruments emphatically demonstrate the superior performance of ruggedized taut band suspension meters over conventional ruggedized pivoed meters. The problem of ribbon breakage during the high shock tests was analyzed with an accelerometer-oscilloscope technique. A good measure of progress was attained in suspension ribbo fabrication. Quantities of the smallest size ribbon required for instruments on this contract were made. Engineering drawing for the 1 inch - 180 degrees and the 2-1/2 and 3-1/2 inch 250 degree meters were completed. The short taut band suspension ribbons permit the over-all dimensions to be physically interchangeable with conventional pivoted type meters. (Author)
