Functional Features Non-contact measurement eliminates mechanical wear between probe and rotating shaft. 10-meter integrated shielded coaxial cable supports long-distance wiring between field probe and control cabinet. High temperature resistant stainless steel and ceramic packaging adapts to high temperature bearing housing environment. CON011 signal converter processes high-frequency sensing signal and outputs standard analog signal for monitoring rack input. Built-in cable break fault detection function identifies cable damage and outputs fault alarm. High measurement resolution captures micrometer-level shaft vibration displacement. Strong anti-electromagnetic interference performance for complex industrial electromagnetic field. Threaded mounting structure supports fine adjustment of installation gap.
Application Scenarios Steam turbine shaft vibration monitoring, centrifugal compressor shaft displacement measurement, large generator set condition monitoring, gas turbine online monitoring system, large fan and pump vibration protection system.
Performance Parameters High linearity within full measurement range. Micrometer-level displacement resolution for tiny vibration detection. Cable break detection reliably identifies cable damage and triggers fault signal. Output analog signal maintains stable linear relation with gap variation after long-time continuous operation. Probe maintains stable sensing characteristic under continuous high temperature and vibration. CON011 converter has stable signal conversion performance for long cable measurement channel.
Material Composition Probe housing: High temperature resistant stainless steel alloy. Sensing coil: High temperature enameled copper winding encapsulated in ceramic material. Probe cable: Fluorine plastic insulated shielded coaxial cable. housing: Anodized aluminum alloy metal casing. PCB inside converter: FR4 multi-layer printed circuit board with conformal coating. Core Electronic Components: High-frequency oscillation chip, signal conditioning circuit, A/D converter, analog output driving chip, cable fault detection circuit. Fasteners: Stainless steel probe lock nut, DIN rail clip for converter. Insulating material: High temperature ceramic and fluorine plastic insulator.
Structural Features Cylindrical threaded probe body, ceramic tip encapsulates sensing coil. 10-meter shielded coaxial cable integrated at rear of probe body. External thread matched with lock nut to fix probe after gap adjustment. converter is rectangular aluminum casing with DIN rail clip on back side. Terminal block arranged on converter side for power supply and analog signal wiring. Internal circuit separates high-frequency excitation section and analog signal processing section.
Working Principle signal converter generates high-frequency alternating excitation current and transmits it to probe coil through 10-meter coaxial cable. Alternating magnetic field radiates from probe tip. Eddy current is induced on metal shaft surface near probe tip. Eddy current produces reverse magnetic field and changes impedance of probe coil. The coil impedance value changes linearly with gap between probe tip and metal shaft. The converter detects coil impedance variation, calculates gap value and converts measurement result into standard analog signal. If probe cable breaks, fault detection circuit detects abnormal coil impedance and outputs fault state. Upper monitoring system receives analog signal and calculates shaft vibration and shaft position value.
Installation Requirements Screw PR6424010-130 probe into threaded hole of bearing housing, adjust probe tip and shaft gap into working range, tighten lock nut. Lay 10-meter coaxial cable inside protection conduit, avoid sharp bending and tensile pulling. Mount converter on DIN rail inside control cabinet, keep away from high power heat source and high voltage cable. Connect -24VDC power supply and analog signal output wiring to converter terminal block. Use shielded twisted pair cable for analog signal transmission, single-point grounding of shielding layer. Set target material parameter in monitoring system according to shaft metal material. Complete gap calibration with standard target block before machine startup.
Usage Precautions Probe tip must not touch rotating shaft during machine running, collision will permanently damage probe coil and ceramic tip. Do not pull, squeeze or bend coaxial cable below minimum bending radius. Cutting and splicing integrated coaxial cable is forbidden, which destroys measurement linearity. converter must be installed inside cabinet within rated temperature range. Check probe installation gap and cable integrity during regular equipment maintenance. Strong magnetic field near probe installation point affects measurement precision. Calibration is mandatory after probe replacement.
