Development of MUltichannel data system

Abstract

A complete data system which can accept ten channels of millivolt data has been designed and developed at N.A.L., Bangalore. The system uses a maximum number of indigenous components. The shaft digitiser and translator are made at N.A.L. The basic sensing element is a self-balancing type potentiometric recorder. The system is modular in construction and capable of different degrees of sophistication. Also different printing formats can be accomodated without difficulty. The system finds extensive applications in quasi-static measurements of strain gauge outputs.
