Torque transducer “deaf” to IGBT noise

By Control Engineering Staff December 1, 1999

Hoffman Estates, Ill. -New technology makes MCRT 4900V dc-operated noncontact torque meters insensitive to severe electromagnetic interference from IGBT-based adjustable speed drives. Its ferrite-free signal transformer is also immune to vibration, hydraulic fluids, and harsh environments. The transducers interface directly to PC and PLC controllers and data acquisition systems. They feature bi-directional operation from stall to maximum speed, dual
