Functional Features The probe features superior side-view characteristics for installation in confined spaces with counter bore or sideview restrictions. The 5 mm tip diameter enables small target measurement. The armored cable with FEP outer jacket protects against abrasion, crushing, and chemical exposure. The probe has increased chemical resistance compared to previous RAM probes. The ClickLoc connector prevents loosening under vibration.
Application Scenarios Compact compressor monitoring in abrasive environments, small pump vibration measurement with cable protection, refrigeration equipment monitoring in harsh conditions, process gas compressor installations with mechanical wear risks, motor bearing monitoring with armored cable routing, gearboxes in industrial environments with debris.
Performance Parameters The probe delivers 7.87 V/mm sensitivity with linearity within system specifications over the 1.5 mm range. The armor adds approximately 100 g to the probe weight. The 1.0 meter cable maintains stable electrical characteristics. The system maintains full interchangeability without recalibration.
Material Composition Probe tip is polyphenylene sulfide (PPS). Probe case is AISI 304 stainless steel. Cable is 75 Ω triaxial with FEP insulation. Armor is flexible stainless steel with FEP outer jacket. Connector material is gold-plated brass.
Structural Characteristics The probe features M8 x 1 metric thread with a compact 1.2 inch case length. The 0.0 inch unthreaded length means the thread extends to the probe shoulder. The armored cable has an increased outside diameter for mechanical protection. The probe comes with a locknut for secure mounting.
Working Principle The probe generates a high-frequency electromagnetic field at the 5 mm probe tip. Eddy currents induced in the conductive target surface modify the RF field characteristics. The Proximitor Sensor measures these modifications and outputs a DC voltage proportional to the gap distance.
