Functional Features The 9.0 meter cable length eliminates the need for an intermediate extension cable in many remote installation scenarios. The probe features front and rear seals combined with FluidLoc cable to prevent moisture ingress. Special high-temperature ClickLoc connectors are standard. The multiple agency approval option ensures compliance with international safety standards. The probe is fully interchangeable with other 3300 XL 25 mm components.
Application Scenarios Power plant steam turbine differential expansion monitoring, remote compressor monitoring installations, large generator shaft position measurement, distributed machinery protection systems, offshore platform rotating equipment monitoring, petrochemical processing equipment in hazardous locations.
Performance Parameters The probe delivers 0.787 V/mm sensitivity with a linear measurement range of 12.7 mm. The 9.0 meter cable maintains signal integrity through the triaxial shielded construction. The system maintains CE mark compliance and satisfies ATEX, IECEx, and CSA hazardous area requirements. The probe operates continuously at 200°C with 250°C peak tolerance.
Material Composition Probe tip is polyetheretherketone (PEEK). Probe case is AISI 304 stainless steel. Cable is 75 Ω triaxial with PFA-insulated FluidLoc construction. Connector material is gold-plated brass. The pressure seal uses a Viton O-ring and compression seal.
Structural Characteristics The probe features M30 x 2 metric thread with a locknut containing pre-drilled safety wire holes. The 60 mm case length provides substantial thread engagement for secure mounting. The non-armored cable has a smaller outside diameter for flexible routing in confined spaces. The ClickLoc connector features a removable collar for routing through tight clearances.
Working Principle The probe generates a high-frequency electromagnetic field at the 25 mm diameter probe tip. Eddy currents induced in the target surface modify the RF field characteristics. The Proximitor Sensor measures these modifications and outputs a DC voltage proportional to the gap distance. The 9.0 meter cable transmits the RF signal with minimal attenuation due to the triaxial shielded construction.
