Technical Specifications Probe Tip Diameter:18 mm Linear Measurement Range:0~4.06 mm Insulation Material: PTFE Operating Temperature:-55℃ ~ +177℃ Connector: Microdot connector Frequency Response:0~10kHz
Functional Features 18mm large probe tip with wide linear measuring range for heavy machinery. Customized configuration according to site engineering requirements. High temperature resistant probe and cable adapt to 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 Custom measuring point solution for large steam turbine and gas turbine shaft monitoring. Thrust bearing displacement measurement of heavy-duty centrifugal compressor. Power plant generator rotor online condition monitoring. Petrochemical plant critical rotating machinery protection system. Large fan and heavy pump rotor vibration measurement with customized parameters.
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 terminal. Anti-vibration locking nut to prevent gap drift.
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.
