Technical Specifications Probe Tip Diameter:12 mm Linear Measurement Range:0~3.05 mm Integral Cable Length:10m Insulation Material: PTFE Operating Temperature:-55℃ ~ +177℃ Connector: Microdot connector Frequency Response:0~10kHz
Functional Features 12mm standard probe tip with stable linear measurement range. 10m long integral cable for remote measuring point layout. High temperature resistant probe and cable adapt to hot industrial measuring positions. Stable signal output under strong vibration environment. Stainless steel threaded probe body with lock nut for gap adjustment and locking. Compatible with Bently 3300 series proximitor system.
Application Scenarios Shaft vibration monitoring of turbine, compressor and generator. Axial thrust displacement measurement of medium and large rotating machinery. Power plant rotating equipment online condition monitoring. Petrochemical plant critical compressor protection system. Vibration measurement of industrial large fan and pump rotor.
Structural Characteristics Stainless steel threaded probe body fitted with lock nut. High temperature PTFE insulated 10-meter integral cable. Hermetically sealed coil assembly inside probe tip. Microdot metal connector at cable terminal. Anti-vibration locking nut to prevent gap drift under equipment vibration.
Working Principle High-frequency excitation signal from matched proximitor is transmitted to coil inside probe tip. Alternating magnetic field induces eddy current on metal rotor surface. Coil impedance changes along with gap variation between probe tip and rotor. Impedance signal returns to proximitor through integral cable and is converted into linear analog voltage signal for real-time gap and vibration measurement.
Installation Requirements Screw probe into threaded mounting hole of equipment casing. Adjust static gap between probe tip and rotor target according to calibration requirement. Tighten lock nut firmly after gap setting to prevent loosening caused by machine vibration. Arrange cable path with enough slack to avoid tension force. Separate signal cable from high voltage power cable to reduce electromagnetic interference. Check target metal surface size and flatness before installation.
