title: Electronic stabilization system for an oscillating vane pressure gauge.
abstract: An electronic stabilization system for an oscillating vane pressure gauge is described. A new continuous drive method is used, obviating the necessity for reliance on mechanical filtering by the vane to produce stable oscillation amplitude. The parameter, damping coefficient, can be measured as being proportional to dc voltage. The dc correction signal is generated with attention to system stability so that stable operation is achieved quickly. Experimental results showing proportionality between the dc correction voltage and damping ratio are presented.
