Woodward 997-149
Professional magnetic pickup speed signal conditioning and isolation conversion unit, specially used for processing engine and turbine magnetic speed sensor weak pulse signal. It amplifies, shapes, isolates and converts the original weak sine wave signal into standard square wave pulse signal, which can be directly accessed into PLC, governor and control system main controller. The device has high signal amplification gain and anti-interference ability, can work stably in strong electromagnetic interference environment, solve the problem of weak speed signal distortion and loss in industrial field.
