Product Overview
The Bently Nevada 330780-91-00 is part of the 3300 XL 11 mm Proximity Transducer System, designed for non-contact vibration and displacement measurements. It features a longer linear range than the standard 8 mm system, making it ideal for large shaft and thrust position applications.
Key Applications
-
Axial thrust position measurements
-
Rod position and rod drop on reciprocating compressors
-
Differential expansion on steam turbines
-
Zero speed and tachometer signal detection
-
Phase reference (Keyphasor) measurements
Product Advantages
-
Extended linear range (up to 4.0 mm typical, 5.0 mm extended)
-
High resistance to RFI/EMI interference
-
DIN-rail or panel mountable design
-
SpringLoc terminal strips for fast, tool-free wiring
-
Durable design with armored cable options
-
Enhanced environmental protection with connector protectors
