- 3300 XL 50 mm Proximitor Sensor
- 3300 XL 50 mm Proximity Transducer System
- Two transducers observing the same side of a collar
Like all 3300 XL series proximity sensors, the 3300 XL 50mm proximity sensor boasts the same advanced features. Its slim design allows for mounting on high-density DIN rails or using more traditional panel mounting methods. Enhanced RFI/EMI immunity enables the 3300 XL proximity sensor to achieve European CE certification without any special installation. This RFI immunity protects the sensor system from interference from nearby high-frequency radio signals. The SpringLoc terminal block on the proximity sensor allows for faster and safer field wiring without special installation tools.
The large-diameter coil gives the system a maximum linear range of 27.9mm (1100 mil), the longest linear range in our eddy current sensor series. The linear measurement range of the 3300 XL 50 mm sensor system makes it ideal for measuring differential expansion (DE) or rotor expansion (RX) in large steam turbine generators, caused by the difference in expansion rates between the turbine rotor and the generator stator (casing).
The 330878-90-00 Bently Nevada Proximitor Sensor may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Typical transducer mounting arrangements that require the 3300 XL 50 mm Transducer’s long linear range include:
- Two transducers observing the same side of a collar
- Two complementary input transducers observing opposite sides of a collar, effectively doubling the measurable DE range
Differential Expansion (DE): Measures the difference in relative expansion between the turbine rotor and its casing due to thermal stress during startup and shutdown.
Rotor Expansion (RX): Tracks long-distance axial movement of the target shaft to ensure that moving parts do not collide with stationary components.
Asset Protection Monitoring: Provides critical input data for industrial turbines, generators, and large process compressors.
