EMERSON PR6423/00R-000+CON021 Eddy current sensor module

Specific parameters
PR6423/00R-000 Eddy Current Sensor:
Measurement range: ± 1.0mm (linear range 2.0mm), sensitivity 8V/mm, resolution ≤ 0.1 μ m.
Frequency response: 0-10kHz, capable of capturing high-frequency vibration signals (such as blade flutter).
Working temperature: -35 ℃ to+200 ℃ (standard model), PR6424 series (resistant to 380 ℃) can be selected for high temperature scenarios.
Installation method: M10 × 1.0 metric thread or 3/8 “-24UNF imperial thread, cable length can be selected from 1-20 meters (armored or unarmored).
Calibration material: The factory pre calibration material is 42CrMo4 steel, suitable for most industrial metal surfaces.
CON021 preamplifier:
Signal output: DC voltage -20V to -4V (linear range), superimposed with AC signal proportional to vibration amplitude, supporting 4-20mA or 0-10V conversion (requires external transmitter).
Power supply requirements: 24V DC (± 10%), redundant power input, power consumption ≤ 5W.
Diagnostic function: Real time monitoring of sensor circuit status (open/short circuit), triggering the “channel fault” indicator light, automatically resetting the output signal and activating the alarm relay.
Protection level: IP20 (with protective casing), can be directly installed on the equipment site.

Product Performance
High precision measurement:
Linearity error ≤ ± 1% FS, meeting the stringent requirements of API 670 for monitoring rotating machinery.
The resolution reaches micrometer level and can capture small changes in shaft vibration (such as sub micrometer displacement).
Anti interference capability:
Differential signal transmission and shielded armored cable design effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI).
Wide working temperature range, suitable for high temperature environments (such as gas turbine exhaust sections) and low temperature scenarios (such as wind turbine gearboxes).
Intelligent diagnosis:
CON021 has a built-in microprocessor that can remotely configure parameters, view waveforms, and diagnose information. It supports RS232/485 interface and configuration software connection.
Fault warning function: When a signal mutation is detected (such as a 30% increase in vibration value within 2 seconds), the protection shutdown logic is automatically triggered.
