Description
The 330850-50-05 3300 XL 25 mm Proximitor Sensor is a panel-mount eddy-current signal conditioner designed for turbine monitoring and automated control systems. The 330850-50-05 3300 XL 25 mm Proximitor Sensor accepts one non-contacting 25 mm probe with extension cable and converts axial rotor displacement into a 0.787 V/mm output across a 12.7 mm linear range. Operating on −17.5 to −26 Vdc at 12 mA with a 50 Ω output, the 330850-50-05 3300 XL 25 mm Proximitor Sensor transmits accurate readings to DCS, PLC, or vibration monitoring systems. Its A380 aluminum housing supports operation from −51°C to +100°C and tolerates 100% condensing humidity when connectors are protected. Multiple agency approvals allow the 330850-50-05 3300 XL 25 mm Proximitor Sensor to be used in automated turbine and generator control loops worldwide. Low supply sensitivity (<2 mV/V) ensures precise voltage output even under DC power variations, enabling continuous measurement of differential expansion and real-time rotor movement verification during startup, shutdown, or load changes.
Applications
Measure differential expansion on steam turbines
The 330850-50-05 3300 XL 25 mm Proximitor Sensor monitors rotor-to-casing axial movement using its 12.7 mm linear range and 0.787 V/mm output. Its A380 aluminum housing allows installation close to turbine rotors, providing precise differential expansion measurements during startup, load changes, or shutdown sequences.
Track generator shaft position
The 330850-50-05 3300 XL 25 mm Proximitor Sensor transmits real-time axial displacement signals to DCS or PLC systems. Its low supply sensitivity (<2 mV/V) ensures accurate rotor position tracking for automated control during rotational speed ramps.
Monitor compressor rotor collars or ramps
The 330850-50-05 3300 XL 25 mm Proximitor Sensor operates in temperatures from −51°C to +100°C and 100% condensing humidity, making it suitable for continuous measurement of axial shaft movement on high-speed compressor rotors.
Specifications
|
Proximitor Sensor Input: |
Accepts one noncontacting 3300 XL 25 mm Proximity Probe and Extension Cable. |
|

Requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption, -23 Vdc to -26 Vdc with barriers. Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range. |
|
Supply Sensitivity: |
Less than 2 mV change in output voltage per volt change in input voltage. |
|
Output resistance: |
50 W |
|
Proximitor Sensor Material: |
A380 aluminum |

Competitive Advantage
Long-distance signal transmission
With 50 Ω output, the 330850-50-05 3300 XL 25 mm Proximitor Sensor transmits precise readings from turbine decks to control panels without amplifiers.
High-temperature operation near machinery
The 330850-50-05 3300 XL 25 mm Proximitor Sensor tolerates continuous +100°C and intermittent +105°C, allowing placement near thrust bearings or rotor assemblies.
Accurate output under DC variations
Less than 2 mV/V supply sensitivity ensures the 330850-50-05 3300 XL 25 mm Proximitor Sensor maintains 0.787 V/mm output during fluctuating DC power.
Humidity tolerance for turbine halls
Sealed connectors allow the 330850-50-05 3300 XL 25 mm Proximitor Sensor to operate in 100% condensing humidity without additional enclosures, enabling use in harsh process areas.
