The MTS Systems 493.25 Universal Conditioner Module is a VMEbus-based signal conditioning component engineered for strain and transducer measurement within MTS testing systems. This plug-in module processes AC and DC sensor inputs with low noise, low drift, and high accuracy, delivering conditioned signals for material testing and structural analysis. It integrates into the Model 493.10 Chassis and operates under control of FlexTest IIm and FlexTest SE digital controllers, supporting full-range calibrations, computer-controlled excitation, and limit detection.
