Product Overview
The Bently Nevada 330850-51-05 is part of the 3300 XL 25 mm Proximitor Sensor system, designed to monitor differential expansion (DE) in mid-to-large steam turbines. It offers a linear measurement range of 12.7 mm (500 mils) and delivers 0.787 V/mm (20 mV/mil) output for precise monitoring of axial movement between the rotor and stator.
Key Applications
-
Differential expansion monitoring in steam turbines
-
Suitable for high-temperature environments
-
Used in turbine generators for axial movement detection
-
Ideal for machines with collar or ramp-type DE targets
Product Advantages
-
Wide linear range (12.7 mm) with stable output
-
High durability in extreme environments (up to 250 °C short term)
-
ClickLoc and FluidLoc technologies for connector reliability and moisture resistance
-
Interchangeable with legacy 7200 series systems
-
CE compliant and certified for hazardous environments

Frequently Asked Questions (FAQ)
Q1: What is the purpose of the 330850-51-05 sensor?
A1: It measures differential expansion in steam turbines by tracking relative axial movement between the rotor and stator.
Q2: What type of signal does the sensor output?
A2: It outputs 0.787 V/mm (20 mV/mil), which provides a linear response over its 12.7 mm range.
Q3: Can it replace older Bently Nevada 7200 series sensors?
A3: Yes, it is designed to be fully compatible as a drop-in replacement.
Q4: What’s the maximum temperature the probe can withstand?
A4: It operates up to 200°C continuously, with short-term tolerance up to 250°C.
Q5: How is the system installed on machinery?
A5: Using optional sliding brackets, the system can be mounted and adjusted for optimal alignment and measurement.
Q6: Is the sensor certified for hazardous areas?
A6: Yes, it has CSA, ATEX, and IECEx certifications for use in Class I/Zone 0 and Zone 2 hazardous locations.
