The LS series of air gap sensors covers a broad measurement range from 5 to 60 mm (linear), features enhanced filtering of noise and spikes and provides outputs for monitoring and protection, including a minimum gap signal for direct protection. Designed for the contactless measurement of air gap in hydroelectric generators, and other large alternators and motors.
