The PR6423/002-0030 CON021 sensor is a highly precise eddy current sensor module with multi-signal output capabilities, widely used in the field of industrial rotating machinery monitoring. Here is a detailed introduction to this sensor:
I. Core Functions and Signal Outputs
Dual-channel Pulse Output
Provides two TTL pulse signals (0 to +5V), one per channel, with pulse width and frequency synchronized with the sensor signal.
Output terminals: Rear panel (z14/z16) or front panel SMB interface “Pulse”.
Application scenarios: Speed measurement, vibration analysis, and other situations requiring precise pulse signals.
Key Phase Signal Output
Two key phase signals (up to 24V), one per channel, used to determine the position and speed of the shaft.
Output terminals: (d14/b14) and (d16/b16), supporting the sampling of other MMS6000 modules.
Limitation: A single key phase output can be connected in parallel to a maximum of 15 MMS6000 modules.
Key Value: The shaft position positioning function is crucial for analysis and diagnostic systems (such as MMS6851), which traditional speed tooth disk signals cannot achieve.
Current Output
Two 0/4 to 20mA current signals, one per channel, for remote transmission of speed or integration into PLC/DCS systems.
Output terminals: z18/b18, z20/b20.
Typical application scenarios
Turbine monitoring
Real-time monitoring of turbine shaft vibration, displacement and speed to prevent faults such as rotor imbalance and shaft misalignment.
Compressor condition assessment
Locating the shaft position through keyphasor signals and combining vibration analysis to diagnose problems such as impeller wear and bearing damage in compressors.
Generator set protection
Integrated speed and vibration monitoring to provide accurate data support for safety functions such as overspeed protection and vibration trip.
Fans and pump equipment
Monitoring the dynamic characteristics of rotating components to optimize equipment operation efficiency and reduce unplanned downtime.
