Technical Specifications Probe Tip Diameter:11 mm Linear Measurement Range:0~2.54 mm Insulation Material:PTFE Operating Temperature:-55℃ ~ +177℃ Connector:Microdot connector Frequency Response:0~10kHz
Functional Features Large linear measuring range for heavy-duty rotating machinery displacement monitoring. Customized configuration according to site engineering requirement. High temperature resistant probe and cable for hot industrial environment. Stable signal output under strong vibration field. Stainless steel threaded probe body with lock nut for gap adjustment. Fully compatible with Bently 3300 series proximitor system.
Application Scenarios Customized measuring point solution for steam turbine and gas turbine shaft monitoring. Centrifugal compressor thrust bearing displacement measurement. Power plant generator rotor online condition monitoring. Petrochemical plant critical rotating machinery protection system. Heavy-duty pump and fan rotor vibration measurement with customized cable length.
Structural Characteristics Stainless steel threaded probe body with locking nut. High temperature PTFE insulated integral cable with customized length. Hermetically sealed coil assembly inside probe tip. Microdot metal connector at cable end. Anti-loosening locking nut for anti-vibration installation.
Working Principle High-frequency excitation signal is sent from proximitor to coil inside probe tip. Eddy current is induced on metal rotor surface. Coil impedance changes with gap variation between probe tip and rotor.
Installation Requirements Mount probe on equipment casing through threaded hole. Adjust static gap between probe tip and rotor target according to system calibration. Tighten lock nut after gap setting to prevent loosening caused by equipment vibration. Arrange cable route to avoid sharp bending and pulling force. Separate signal cable from high voltage power cable to reduce electromagnetic interference. Check target surface flatness and size before installation.
