Product type: 4-channel Proximitor Monitor (eddy current monitoring module), core monitoring unit of 3500 system
Core functions: sensor signal conditioning, parameter measurement, alarm threshold comparison, relay/analog output, online diagnosis
Input configuration: 4 independent eddy current sensor inputs, supporting sensitivity of 3.94mV/μm (100mV/mil) or 7.87mV/μm (200mV/mil), with input impedance of 10kΩ (standard) / 50kΩ (TMR parallel)
Measurement parameters: radial vibration, axial displacement, eccentricity, differential expansion, REBAM®, supporting 1X/2X amplitude/phase static values
Output interface: Each channel features a buffered sensor output (550Ω impedance), a +4~20mA analog output, and an alarm/shutdown relay output
Power Supply and Power Consumption: 24VDC system backplane power supply, typical power consumption of 7.7W, with overvoltage/reverse polarity protection
Physical specifications: Dimensions: 241×24.4×242mm, weight: approximately 0.91kg, standard 3500 rack slot
Operating environment: Temperature -30℃~+65℃, humidity 5%-95% (non-condensing), FCC Part 15 compliant
Configuration and Indication: LED status lights (OK/TX/RX/Bypass), configured through 3500 configuration software, supporting online bypass/diagnostics
Core functions and adaptability
Signal conditioning: Receiving signals from an eddy current sensor, filtering, amplifying, linearizing, converting to standard measurement values, and adapting to 3500 system data acquisition.
Multi-parameter monitoring: Each channel can be independently configured for measurements such as radial vibration, axial displacement, eccentricity, and differential expansion. It supports 1X/2X amplitude and phase monitoring, meeting the needs of rotor dynamics analysis.
Alarm control: Programmable Alert/Danger thresholds, driving built-in relays or external 3500/34 relay module outputs, supporting voting logic (such as 2oo3), reducing the risk of false alarms.
