SCR or PWM? Choosing a Drive for Brushed DC Motors
SCR and PWM drives regulate brushed DC motors in different ways. This comparison covers torque quality, speed range, reversal, braking, electrical noise, thermal behavior, feedback, and retrofit...
330500-05-01: Bently Nevada Velomitor piezo-velocity sensor configured with Option 05 mounting thread adaptor (unavailable for standard 330500, directing NPT installations to model 330525) and Option 01 CSA/US/C hazardous area certification.
This specific configuration incorporates a hermetically-sealed 316L stainless steel case housing embedded solid-state electronics, making it immune to mechanical wear and degradation. Unlike moving-parts velocity transducers, this piezo-velocity sensor can be mounted at any orientation angle. The sensor provides an output sensitivity of 3.94 mV/mm/s (100 mV/in/s) to measure absolute structural, casing, or bearing housing vibration in demanding industrial machinery environments.
