variable reluctance vibration speed sensor / magnetic
Bruel and Kjaer
variable reluctance, magnetic
The Magnetic Transducer MM-0002 is designed to serve as a electromagnetic vibration exciter or a sensitive vibration pickup. The part that moves is either one of the increased permeability discs that is glued onto the vibrating structure at the front of this electromagnetic variable reluctance deviceor the tested structure if it is ferromagnetic.
