Technical Specifications Probe Tip Diameter: 8 mm Linear Measurement Range: 0~2.03 mm Integral Cable Length:16m Insulation Material: PTFE Operating Temperature: -55℃ ~ +177℃ Connector Type: Microdot connector Frequency Response:0~12kHz
Functional Features 8mm probe tip with medium linear measuring range. 16m long integrated cable for remote measuring point layout. High temperature resistant probe and cable for high temperature working area. Stable signal transmission under strong vibration condition. Stainless steel threaded body with lock nut for gap adjustment and fixing. Compatible with Bently 3300 series proximitor preamplifier system.
Application Scenarios Shaft vibration monitoring of steam turbine and gas turbine requiring long cable. Thrust displacement measurement of centrifugal compressor for remote measuring points. Online condition monitoring of power plant generator rotor. Critical rotating equipment protection system in petrochemical plants.
Structural Characteristics Stainless steel threaded probe body fitted with locking nut. High temperature PTFE insulated 16-meter integral cable. Hermetically sealed coil assembly inside probe tip. Microdot metal connector at cable terminal. Anti-vibration locking nut structure for field installation.
Working Principle High-frequency excitation signal from proximitor is sent to coil in probe tip. Eddy current is induced on metal rotor surface. Coil impedance changes with gap variation between probe and rotor.
Installation Requirements Mount probe into threaded mounting hole of 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 by vibration. Arrange long cable route to avoid sharp bending, tension and extrusion. Separate signal cable from high voltage power cable to reduce electromagnetic interference. Check target metal surface quality before installation.
