Bently Nevada 330980-51-00 3300 XL NSv Proximitor Sensor
Product Description
The Bently Nevada 330980-51-00 is part of the 3300 XL NSv Proximity Transducer System, engineered for machinery where space constraints exist—such as centrifugal compressors and small shaft applications. It integrates a probe, extension cable, and this Proximitor Sensor for accurate non-contact displacement, vibration, and position measurements.
Applications
-
Radial vibration and position monitoring on small shafts
-
Axial (thrust) position measurement
-
Phase reference detection (Keyphasor)
-
Zero-speed and tachometer measurements
-
Retrofits for 3300 RAM and 190 series systems
Advantages
-
Compact DIN-rail or panel mount form factor
-
Enhanced immunity to RFI/EMI
-
Fast installation with SpringLoc terminals
-
Compatible with legacy Bently Nevada systems
-
Sealed PPS tip and Viton O-ring for chemical and pressure resistance
