Technical Specifications Probe Tip Diameter: 11mm Linear Measurement Range: 0 to 2.54 mm Operating Temperature: -55℃ ~ +177℃ Integral Cable Length: 4m Insulation Material: PTFE Connector Type: Microdot Recommended Target: Conductive metal material Frequency Range: 0~10kHz
Functional Features Large linear measuring range for heavy-duty machinery displacement monitoring. High temperature resistant probe and cable for harsh thermal environment. Stable eddy current signal output under strong vibration condition. Threaded body structure for convenient installation and gap adjustment. Full compatibility with Bently 3300 series proximitor and extension cables. Built-in coil sealed structure, moisture and corrosion resistant.
Application Scenarios Large steam turbine and gas turbine shaft monitoring. Heavy-duty centrifugal compressor thrust bearing displacement measurement. Power generation unit rotor vibration online protection. Oil refinery and chemical plant rotating equipment condition monitoring. High-speed large fan and water pump machinery protection system.
Structural Characteristics Stainless steel threaded probe body, equipped with locking nut. High temperature PTFE insulated integrated cable. Hermetically sealed coil assembly inside probe tip. Precision microdot connector at cable end. Anti-loosening structure to resist equipment vibration.
Working Principle High-frequency excitation signal is transmitted from proximitor to the coil inside probe tip. Eddy current is induced on the surface of the metal rotor target. The coil impedance changes as the gap between probe and rotor varies.
Installation Requirements Mount the probe on the machine casing by threaded fitting. Tighten lock nut firmly after gap setting to prevent displacement caused by machine vibration.
