Technical Specifications Probe Tip Diameter: 11 mm Linear Measurement Range: 0~2.54 mm Integral Cable Length: 4m Insulation Material: PTFE Operating Temperature: -55℃ ~ +177℃ Connector: Microdot connector Frequency Range: 0~10kHz
Functional Features Large linear measuring range for heavy machinery displacement monitoring. High temperature resistant probe and cable for hot equipment area. Stable eddy current signal output under strong vibration. Threaded body with lock nut for gap adjustment and fixing. Full compatibility with Bently 3300 series proximitor and extension cable. Sealed coil assembly, moisture and corrosion resistant.
Application Scenarios Large steam turbine and gas turbine shaft vibration monitoring. Heavy-duty centrifugal compressor thrust displacement measurement. Power plant generator rotor online protection system. Petrochemical plant critical rotating equipment condition monitoring. Large industrial fan and water pump rotor displacement supervision.
Structural Characteristics Stainless steel threaded probe body, equipped with locking nut. High temperature PTFE insulated integrated cable. Hermetically sealed coil inside probe tip. Microdot metal connector at cable terminal. Anti-vibration locking structure to prevent gap drift.
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 Install probe on machine casing through threaded fitting. Adjust static gap between probe tip and rotor target according to system calibration requirement. Tighten lock nut firmly after gap setting to avoid displacement caused by vibration. Lay cable with proper slack to avoid tension under thermal expansion.
