Description
The 330850-50-CN 3300 XL 25 mm Proximitor Sensor is a panel-mounted transducer system designed for automated monitoring of steam turbines, compressors, and generators. The 330850-50-CN 3300 XL 25 mm Proximitor Sensor accepts one 25 mm non-contact 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 50 Ω output, the 330850-50-CN 3300 XL 25 mm Proximitor Sensor delivers precise shaft position signals to DCS or PLC systems. Its A380 aluminum housing supports temperatures from −51°C to +100°C and 100% condensing humidity when connectors are protected. With less than 2 mV/V supply sensitivity, the 330850-50-CN 3300 XL 25 mm Proximitor Sensor maintains accurate output during DC voltage fluctuations. Multiple agency approvals allow integration into global automated control loops, while high-temperature ClickLoc connectors and sealed probe tips ensure reliable operation near rotor collars and thrust bearings.
Applications
Measure differential expansion on turbines
The 330850-50-CN 3300 XL 25 mm Proximitor Sensor measures rotor-to-casing axial displacement using its 12.7 mm linear range and 0.787 V/mm output. Its A380 aluminum housing and panel mount allow installation close to turbine rotors, providing precise differential expansion readings during startup, load changes, or shutdown sequences.
Track generator rotor axial position
The 330850-50-CN 3300 XL 25 mm Proximitor Sensor transmits real-time shaft movement to DCS or PLC systems. With less than 2 mV/V supply sensitivity and 50 Ω output resistance, it ensures consistent axial position tracking under varying DC supply voltages.
Monitor compressor rotor collars or ramps
The 330850-50-CN 3300 XL 25 mm Proximitor Sensor operates reliably from −51°C to +100°C in 100% condensing humidity environments, making it suitable for continuous monitoring of high-speed compressors.
Specifications
|
Proximitor Sensor Input: |
Accepts one noncontacting 3300 XL 25 mm Proximity Probe and Extension Cable. |
