Product Overview
The Bently Nevada 330850-50-05 is part of the 3300 XL 25 mm Proximitor Sensor System. It offers a non-contact measurement solution designed for differential expansion (DE) monitoring in mid- to large-sized steam turbines. The system includes a 25 mm proximity probe, extension cable, and Proximitor sensor, delivering a linear output of 0.787 V/mm over a 12.7 mm range.
Key Applications
-
Differential Expansion (DE) measurement in turbine generators
-
Rotor-stator movement monitoring
-
High-temperature and high-vibration industrial environments
-
Suitable for AISI 4140 steel and other target materials (on request)
Product Advantages
-
Wide Linear Range: 12.7 mm range ensures precise DE monitoring
-
High Temp Endurance: Probe operates continuously up to 200°C, short-term up to 250°C
-
Field-Proven: Reliable even in harsh steam turbine environments
-
System Compatibility: Direct upgrade path from 7200 and legacy systems
