Quick Detail

Description

330101-37-57-10-02-05 is a 3300 XL 8 mm proximity probe designed for automation systems that require continuous displacement, vibration, and speed feedback from rotating machinery. 330101-37-57-10-02-05 uses an eddy current measuring principle to generate an output voltage proportional to the gap between the probe tip and a conductive target, supporting both static position and dynamic vibration monitoring in automated control environments.

With a linear range of 2 mm (80 mils), 330101-37-57-10-02-05 supports precise shaft position tracking in turbines, compressors, pumps, and motors integrated with DCS or PLC platforms. 330101-37-57-10-02-05 features a 3/8-24 UNF threaded probe case, a minimum unthreaded length of 3.7 in, and a minimum case length of 5.7 in, allowing flexible mounting in compact machine housings.

The total probe length of 1.0 meter and miniature coaxial ClickLoc connector enable reliable signal transmission with a typical extension cable capacitance of 69.9 pF/m. 330101-37-57-10-02-05 operates from -52°C to +177°C and maintains output variation below 2 mV per volt of supply change, supporting automated condition monitoring under wide temperature ranges. CSA, ATEX, and IECEx approvals allow 330101-37-57-10-02-05 to be deployed in industrial automation systems located in regulated environments.

Applications

Shaft Vibration Measurement on Turbines
330101-37-57-10-02-05 is installed at journal bearing locations on steam and gas turbines to capture radial shaft vibration within a 2 mm linear range. By using the 50 Ω output and controlled extension cable capacitance of 69.9 pF/m, 330101-37-57-10-02-05 delivers displacement signals that can be directly processed by automated protection and vibration monitoring systems.

Axial Position Tracking in Compressors
Mounted near thrust bearings, 330101-37-57-10-02-05 measures axial shaft movement during load variation and start-up sequences. The defined probe geometry, including a 3/8-24 UNF thread and 0.563 in maximum thread engagement, allows 330101-37-57-10-02-05 to fit into compact compressor housings while maintaining accurate position feedback for control logic.

Speed and Phase Reference Input
When aligned with a keyway or target notch, 330101-37-57-10-02-05 provides speed and phase reference signals used for overspeed detection and sequence control. The miniature coaxial ClickLoc connector and 1.0 meter probe length allow 330101-37-57-10-02-05 to transmit clean signals to automation cabinets with minimal signal loss.

Rotating Equipment Monitoring in Hazardous Areas
With CSA, ATEX, and IECEx approvals, 330101-37-57-10-02-05 is applied on pumps, compressors, and turbines operating in hazardous zones. The operating temperature range of -52°C to +177°C allows 330101-37-57-10-02-05 to support automated monitoring under both cold start and high thermal load conditions.

Specifications

Competitive Advantage

Low Output Change Under Supply Variation
330101-37-57-10-02-05 limits output change to less than 2 mV per volt of supply input variation, allowing automation systems to maintain consistent displacement readings even when cabinet power levels fluctuate.

Defined Mechanical Dimensions for Tight Installations
The minimum unthreaded length of 3.7 in and minimum case length of 5.7 in allow 330101-37-57-10-02-05 to be installed in restricted bearing housings where probe clearance is limited.

Controlled Signal Behavior Over Cable Length
With a typical extension cable capacitance of 69.9 pF/m, 330101-37-57-10-02-05 supports predictable signal behavior over distance, simplifying parameter setting in vibration and position monitoring software.

Wide Operating Temperature Range
The -52°C to +177°C operating and storage temperature range allows 330101-37-57-10-02-05 to remain active on machinery exposed to extreme ambient and process temperatures without requiring auxiliary thermal protection.
