The PMSS Full Quadruple 1/4 Bridge Card is a specialized simulation module designed for structural health monitoring and aerodynamic testing. It allows for the high-fidelity simulation of strain gauge sensors (1/4 bridge configuration) used in the validation and calibration of airborne and ground-based data acquisition systems. With integrated digital resistance control, it provides repeatable and accurate stimulus for complex stress-test scenarios.
