Quick Detail

Description

The 144181-50 3300 XL 5/8 mm Proximitor Sensor is a high-performance eddy current proximity sensor designed for precise non-contact displacement measurement in advanced industrial automation systems. This Proximitor sensor is widely used in machinery condition monitoring, rotating equipment protection, and process automation applications, where reliable real-time position and vibration feedback is critical. Utilizing proven eddy current measurement technology, the 3300 XL Proximitor sensor accurately detects the displacement of ferromagnetic conductive targets without physical contact, ensuring stable operation in harsh industrial environments.

With a 5/8 mm probe tip diameter and a typical measurement range of up to 2.0 mm, the 144181-50 Proximitor sensor delivers a standard 4–20 mA output signal that integrates seamlessly with PLC, DCS, and other automation control platforms. The sensor supports high resolution and excellent linearity, enabling precise shaft position monitoring, axial displacement detection, and machinery health diagnostics. Its wide operating temperature range and shielded integrated cable make the 3300 XL Proximitor sensor a reliable solution for demanding automation, power generation, oil and gas, and heavy industry applications.

Applications

Shaft Position Monitoring in Turbomachinery
With a measurement range of 0–2.0 mm and resolution below 1 µm, the 144181-50 Proximitor Sensor is ideal for continuous shaft position monitoring in turbines and compressors. The 0–10 kHz response frequency allows accurate detection of dynamic shaft movement during startup, shutdown, and steady-state operation.

Vibration Measurement for Rotating Equipment
The sensor’s high-frequency response up to 10 kHz enables precise vibration monitoring of motors, pumps, and gearboxes. The 4–20 mA output signal ensures stable transmission of vibration data to automation control systems over long distances.

Axial Displacement Protection Systems
In axial thrust monitoring applications, the 8.0 mA/mm sensitivity provides fast and accurate detection of axial movement. This allows automation systems to trigger alarms or shutdowns before displacement exceeds safe mechanical limits.

Condition Monitoring in Harsh Industrial Environments
Operating reliably from –40 °C to +260 °C, the 3300 XL Proximitor Sensor is suitable for automation systems exposed to extreme temperatures, such as power plants and petrochemical facilities, without degradation in measurement accuracy.

Automated Process Control Feedback
The sensor’s ≤ 600 Ω load resistance compatibility and low power consumption of < 1.2 W make it well suited for continuous feedback loops in automated process control, where stable displacement data is required for precision control logic.
