Bently Nevada 190501-00-00-CN Velomitor CT Velocity Transducer

Description

The 190501-00-00-CN is a Velomitor CT Velocity Transducer, configured with the Option 00 mounting and connection interface and the -CN suffix for China hazardous area compliance. This piezoelectric velocity sensor is a specialized low-frequency version of the standard Velomitor transducer, designed to measure casing vibration velocity on rotating machinery such as cooling tower fans and air-cooled heat-exchanger fan assemblies. It operates effectively on machinery with rotation speeds typically at or above 90 rpm (100 to 300 rpm typical).

This transducer converts machine casing motion into a proportional voltage output, providing a critical signal for vibration monitoring systems. The 190501-00-00-CN variant features a 3/8-24 mounting interface (No Stud - Option 00) and a standard MIL-C-5015 connection interface (Option 00). The -CN suffix indicates the inclusion of hazardous area approval documentation for China (NEPSI and CCC), ensuring compliance with regional safety standards.
