Technical Specifications Probe Tip Diameter:12 mm Linear Measurement Range:0~3.18 mm Integral Cable Length:2m Insulation Material: PTFE Operating Temperature:-55℃ ~ +177℃ Connector: Microdot connector Frequency Response:0~10kHz
Functional Features 12mm large probe tip with wider linear measurement range. 2m short integral cable for measuring points close to proximitor. High temperature resistant probe and cable adapt to hot installation environment. Stable signal output under strong vibration condition. Stainless steel threaded body with lock nut for gap adjustment and fixing. Fully compatible with Bently 3300 series proximitor system.
Application Scenarios Shaft vibration monitoring of large steam turbine and gas turbine. Axial thrust displacement measurement of heavy-duty centrifugal compressor. Rotor online protection of power plant large generator set. Critical rotating machinery condition monitoring in petrochemical plant. Displacement measurement of large industrial fan and pump rotor.
Structural Characteristics Stainless steel threaded probe body fitted with locking nut. High temperature PTFE insulated 2-meter integral cable. Hermetically sealed coil assembly inside probe tip. Microdot metal connector at cable terminal.
Working Principle High-frequency excitation signal is transmitted from proximitor to coil inside probe tip. Eddy current is induced on metal rotor surface. Coil impedance changes along with gap variation between probe tip and rotor.
Installation Requirements Screw probe into threaded mounting hole of equipment casing. Tighten lock nut firmly after gap setting to prevent loosening caused by machine vibration.
