• LEMO plug or screw terminal sensor connection options

• Compatible with EPRO MMS3000/MMS6000 monitoring systems

• Can integrate safety barriers for explosion-proof applications

• Built-in open circuit, short circuit, and reverse polarity protection

• LCD display for real-time parameter status

Working Principle:
The CON021 operates on the eddy current effect principle. The converter amplifies weak sensor signals and linearizes them, outputting voltage signals proportional to shaft vibration and displacement. The device processes both dynamic (vibration) and static (position) parameters simultaneously.

Advantages and Highlights:

• High-precision signal processing with ±0.1% accuracy

• Wide frequency response (0-20,000 Hz) captures full vibration spectrum

• Industrial temperature range (-30°C to 100°C) suits harsh environments

• Anti-interference design ensures reliable measurements in electrically noisy environments

• Flexible sensor connection options accommodate different installation scenarios

• Comprehensive protection features extend equipment service life

Applicable Industries:
Power generation (turbine, generator bearing vibration and shaft displacement monitoring), petrochemical and metallurgy (compressor, pump oil film thickness and dynamic balance), mechanical manufacturing (gearbox, centrifuge shaft eccentricity and radial vibration), and rail transportation (traction motor bearing monitoring).

Model Series:
EPRO CON Series Signal Converters

Installation Requirements:

• 4 x M5 screw fixation supporting wall or DIN rail mounting

• Supply voltage: -23 to 32 V DC

• LEMO plug or screw terminal sensor connection

• IP20 protection rating requires installation within protected enclosure

Usage Precautions:

• Verify correct sensor compatibility (PR6422-PR6426 series)

• Ensure proper supply voltage polarity (-23 to 32 V DC)

• Maintain operating temperature within -30°C to 100°C range

• Use appropriate cable shielding to maintain signal integrity

• Regular calibration recommended for sustained accuracy

• For explosion-proof applications, use designated EX version

• Ensure proper grounding to prevent ground loops and measurement errors
