Technical Specifications Probe Tip Diameter:18 mm Linear Measurement Range:0~4.06 mm Integral Cable Length:10m Insulation Material: Special high temperature resistant material Operating Temperature:-55℃ ~ +232℃ Connector: Microdot connector Frequency Response:0~10kHz
Functional Features 18mm large probe tip with wide linear measuring range. 10m integral cable for long-distance measuring point layout. Ultra-high temperature resistance adapts to superheated equipment measuring points. Stable signal output under high temperature and strong vibration. Stainless steel threaded body with lock nut for gap adjustment and locking. Compatible with Bently 3300 series proximitor preamplifier system.
Application Scenarios High temperature area shaft vibration monitoring of steam turbine and gas turbine. Thrust bearing displacement measurement of high temperature heavy-duty compressor. Power plant high temperature section generator rotor condition monitoring. Petrochemical plant high temperature process rotating machinery protection system. Vibration measurement of high-temperature large industrial fan and pump rotor.
Structural Characteristics High temperature stainless steel threaded probe body fitted with lock nut. Special high temperature resistant insulated 10-meter integral cable. Hermetically sealed high temperature coil assembly inside probe tip. Microdot metal connector at cable terminal. Anti-vibration locking nut to prevent gap drift under vibration.
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 high-temperature equipment casing. Adjust static gap between probe tip and rotor target according to calibration requirement. Tighten lock nut firmly after gap setting to prevent loosening caused by machine vibration. Arrange cable path to avoid sharp bending, tension and extrusion.
