描述
The Bently Nevada 330980-71-CN is part / the 3300 XL NSv Proximity Transducer System, specifically engineered for machinery with space constraints such as centrifugal compressors, small shaft turbines, and process gas compressors. This system includes a proximity probe, extension cable, and Proximitor sensor optimized for measuring vibration, position, and speed in applications where standard 5 mm or 8 mm systems are impractical.
The 330980-71-CN model features a 7.0-meter system length with DIN mounting. Its compact form factor, enhanced EMI/RFI imm件y, and rugged mechanical design make it suitable for harsh industrial environments, including high humidity and corrosive conditions.
