Technical Specifications Applicable System: Bently 3300 series eddy current probe system Terminal Type: Screw clamping terminal Operating Temperature: -40℃ ~ +70℃ Mounting Method: DIN rail mount Insulation: High insulation PCB substrate Relative Humidity: 5%~95%, non-condensing
Functional Features Dedicated terminal interface for eddy current probe measuring loop. Suppresses common mode noise in weak probe signal circuit. Screw terminals for convenient connection and disconnection. Compact structure for cabinet installation. Clear marking for probe, cable and power signal terminals. Stable connection under long-term cabinet vibration.
Application Scenarios Termination for Bently 3300 series proximity probe system. Shaft vibration and thrust displacement measurement circuit wiring. Steam turbine and centrifugal compressor machinery monitoring cabinet. Power plant rotating
equipment protection system. Petrochemical plant non-contact displacement measuring loop wiring.
Performance Parameters Contact resistance: Low and stable for high-precision probe signal Noise suppression: Reduce common-mode interference of weak analog signal Vibration resistance: No loose contact under cabinet vibration
Structural Characteristics Flame retardant plastic housing with DIN rail clip. Screw terminal blocks arranged by signal definition. Internal PCB with noise suppression components. Signal identification marks printed on front panel. Locking buckle to prevent sliding on DIN rail.
Working Principle The eddy current probe signal and power supply line of proximitor are connected to corresponding terminals of this assembly. Internal noise suppression components reduce common-mode electromagnetic interference on signal loop. Signals are transmitted stably between probe, extension cable and proximitor, ensuring accurate gap measurement of rotating shaft.
Installation Requirements Install assembly on standard DIN rail inside control cabinet. Follow Bently wiring drawing to connect probe, extension cable and proximitor. Use matched shielded coaxial cable for probe loop. Separate probe signal cable from high voltage power cable. Tighten terminal screws to avoid bad contact. Check signal stability after wiring completion.
