Description
Engineered for high-precision machinery diagnostics, the 330704-010-080-10-02-CN serves as a rugged, non-contacting displacement sensor within the 3300 XL 11 mm Proximity Transducer System. Designed to measure static and dynamic shaft movement, this system provides a wider linear range of 4 mm (160 mils) compared to standard 8 mm probes, making it highly effective for fluid-film bearing machines such as steam turbines, gas turbines, compressors, and generators.
This specific configuration features a metric M14 x 1.5 threaded case, specified with a 10 mm unthreaded length and an 80 mm overall case length. The sensor is equipped with a 1.0-meter standard coaxial cable terminated with a miniature ClickLoc connector, designed to prevent unintended disconnects under vibration. The "CN" designation indicates country-specific agency approvals for regional compliance.
Features
- Extended linear range of 4 mm (160 mils) for increased measurement span over standard 8 mm proximity probes.
- Robust polyphenylene sulfide (PPS) tip material offers high chemical resistance and protection against harsh industrial fluids.
- AISI 304 stainless steel (SST) case ensures physical integrity in high-vibration applications.
- Miniature coaxial ClickLoc connector provides secure mechanical and electrical connections without special tooling.
- Integrated Viton O-ring seals differential pressure between the probe tip and the sensor case.
Applications
- Steam and gas turbine shaft vibration and axial position monitoring.
- Reciprocating compressor piston rod runout tracking.
- Fluid-film bearing clearance diagnostics in heavy industrial machinery.
- Hydroelectric generator air gap and thermal expansion measurements.

Installation Guidelines
- Ensure physical clearance around the 11 mm probe tip to prevent side-loading or electrical cross-talk from adjacent metal surfaces.
- Apply the proper mounting torque corresponding to the metric M14 thread to prevent thread damage and case deformation.
- Do not bend the coaxial cable beyond its minimum recommended bend radius during routing.
- Protect the ClickLoc connector from moisture and contaminants using terminal boots or self-fusing electrical tape if exposed to the elements.
