Functional Features The 26 mm case length provides a compact installation profile for space-constrained applications. The armored cable features flexible stainless steel with protective outer jacket for protection against abrasion, crushing, and chemical exposure. The probe has front and rear seals with FluidLoc cable to prevent moisture ingress. The multiple agency approvals ensure compliance with international safety standards.
Application Scenarios Compact steam turbine differential expansion monitoring, space-constrained compressor installations, small generator shaft monitoring, industrial pump monitoring in tight housings, reciprocating compressor rod drop measurement, general machinery condition monitoring with limited mounting depth.
Performance Parameters The probe delivers 0.787 V/mm sensitivity with linearity within system specifications over the 12.7 mm range. The armor adds approximately 100 g to the probe weight compared to non-armored versions. The 1.0 meter cable has a DC resistance of 6.2 ± 0.5 Ω. The system maintains full hazardous area compliance.
Material Composition Probe tip is polyetheretherketone (PEEK). Probe case is AISI 304 stainless steel. Cable is 75 Ω triaxial with PFA-insulated FluidLoc construction. Armor is flexible stainless steel with protective outer jacket. Connector material is gold-plated brass.
Structural Characteristics The probe features M30 x 2 metric thread with a locknut containing pre-drilled safety wire holes. The 26 mm case length is one of the most compact configurations available in the 25 mm series. The armored cable has an increased outside diameter for mechanical protection. The probe features a removable collar on the ClickLoc connector.
Working Principle The probe generates a high-frequency electromagnetic field at the 25 mm 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 compact case does not compromise the electrical performance.
