Technical Specifications Probe Tip Diameter: 8 mm Linear Measurement Range: 0~2.03 mm Integral Cable Length: 10m Insulation Material: PTFE Operating Temperature: -55℃ ~ +177℃ Connector Type: Microdot connector Frequency Response: 0~12kHz
Functional Features 8mm probe tip with medium linear range for rotating shaft measurement. 10m long integrated cable for long-distance measuring point layout. High temperature resistant probe and cable adapt to hot field installation. Stable signal output under strong vibration industrial site. Stainless steel threaded body with lock nut for gap calibration. Comes with Chinese version product documentation for local engineering application.
Application Scenarios Shaft vibration monitoring of steam turbine and gas turbine in domestic power plants. Thrust bearing displacement measurement of centrifugal compressor in petrochemical plants. Rotor condition monitoring of large generator sets. Online protection system for critical rotating machinery. Vibration measurement of heavy-duty pumps and fans with long cable routing.
Structural Characteristics Stainless steel threaded probe body equipped with lock nut. High temperature PTFE insulated 10-meter integral cable. Hermetically sealed coil assembly inside probe tip. Microdot metal connector at cable end. Anti-loosening locking nut to prevent gap shift under vibration.
Working Principle Proximitor outputs high-frequency alternating signal to probe coil. Alternating magnetic field generates eddy current on metal rotor surface. Coil impedance changes as the gap between probe tip and rotor changes. Impedance variation signal returns to proximitor and is converted into linear analog voltage to reflect real-time gap, vibration and displacement value of rotating shaft.
Installation Requirements Install probe into threaded hole on equipment casing. Adjust static gap between probe tip and rotor target according to calibration data. Lock nut tightly after gap adjustment to prevent loosening by machine vibration. Arrange cable with enough slack, avoid pulling force caused by thermal expansion.
