Technical Specifications Applicable Probe: 330170 series high temperature proximity probe Power Supply: -24V DC Output Signal: Linear gap voltage signal Operating Temperature: -40℃ ~ +70℃ Mounting: Customized bracket mounting Housing: Cast aluminum alloy shielding housing
Functional Features Customized preamplifier matched for high temperature eddy current probe. Generate high-frequency excitation signal for high temperature probe coil. Convert probe impedance variation into linear analog voltage signal. Built-in self-diagnosis to detect probe cable open and short circuit fault. Aluminum alloy shielding housing for anti-electromagnetic interference. Customized terminal layout to meet site wiring requirement.
Application Scenarios Custom preamplifier solution for high temperature Bently 3300 probe system. High temperature area shaft vibration monitoring of steam turbine and gas turbine. High temperature centrifugal compressor thrust bearing displacement measurement. Power plant high temperature rotor online condition monitoring. Petrochemical plant high temperature critical rotating machinery protection system.
Structural Characteristics Cast aluminum alloy metal housing with customized mounting structure. Internal PCB integrated dedicated oscillator, signal conditioning and fault diagnosis circuit for high temperature probe. Customized screw terminal block for power supply, probe signal and output signal. Cable entry openings for field wiring. Shielded metal housing structure.
Working Principle The dedicated oscillator produces matched high-frequency excitation signal and transmits to high temperature probe coil. Eddy current generated on rotor surface changes coil impedance according to gap distance.
Installation Requirements Fix proximitor to customized rigid bracket, keep away from high temperature heat source. Connect high temperature probe extension cable to signal terminals according to wiring drawing. Connect -24V DC power supply without polarity reversal. Ground aluminum housing to system protective ground. Keep signal cables away from high voltage power lines. Check signal output and loop fault status after wiring completion.
