Product Overview
The Bently Nevada 330850-91-00 is part of the 3300 XL 25 mm Proximity Transducer System. Designed to monitor differential expansion (DE) in steam turbine generators, it provides a precise, linear output of 0.787 V/mm across a 12.7 mm range. The system includes a proximity probe, extension cable, and Proximitor Sensor, making it ideal for harsh high-temperature environments.
Applications
-
Steam turbine differential expansion monitoring
-
Rotor/stator axial growth detection
-
DE collar or ramp-based measurements
-
Mid-size to large generator installations
-
Machinery condition monitoring in power and process industries
Advantages
-
High linearity (12.7 mm) with 0.787 V/mm scale factor
-
Operates in temperatures up to 200 °C (probe)
-
Moisture-resistant FluidLoc cable and dual-seal design
-
Backward compatibility with 7200 and DE Integral systems
-
CE, ATEX, IECEx, and CSA certifications
-
Flexible mounting (DIN-rail or panel) with compact Proximitor Sensor

Frequently Asked Questions (FAQ)
Q1: What is the primary function of the 330850-91-00 sensor?
A1: It monitors differential expansion in steam turbines by measuring the relative axial movement between the rotor and stator.
Q2: What is the linear measurement range of this system?
A2: The system provides a linear measurement range of 12.7 mm (500 mils).
Q3: Can it be used in high-temperature environments?
A3: Yes, the probe operates up to 200 °C continuously and 250 °C intermittently.
Q4: Is the 330850-91-00 backward compatible?
A4: Yes, it replaces 7200 and DE Integral 25 mm transducers without changes to monitor configuration.
Q5: What output does the Proximitor Sensor provide?
A5: It provides a voltage output proportional to the shaft movement, typically -1.5 to -11.5 Vdc.
Q6: Does it require special mounting tools?
A6: No, the SpringLoc terminal strips allow tool-free installation.
Q7: How is moisture prevented from entering the probe?
A7: The system uses dual seals and FluidLoc cable to block moisture ingress.
