Bently Nevada 330500-02-05 Velomitor пьезо-жылдамдық сенсоры

Description

The 330500-02-05 Velomitor Piezo-velocity sensor is a ruggedized, case-mounted transducer used to measure casing vibration in industrial machinery. This sensor utilizes a piezoelectric accelerometer with integrated electronics to provide a signal proportional to velocity, ensuring compatibility with standard vibration monitoring equipment that accepts velocity inputs. Option 02 specifies a 1/2-14 NPT mounting thread, and Option 05 provides CSA/NRTL/C hazardous area approval, facilitating installation in demanding environments.

The sensor functions as a piezoelectric accelerometer and integrates internal electronics within the stainless steel housing to condition the signal to a velocity output. It is typically deployed on fans, blowers, pumps, and motors where casing velocity measurement is required for machinery protection or diagnostic analysis. The 330500 series serves as a direct replacement for moving-coil velocity transducers, offering improved reliability due to the absence of internal wear parts.
