• Suitable for ATEX/IECEx hazardous area certification

CON021 Signal Converter

• Provides excitation frequency to the eddy current probe

• Converts sensor signals into a linearized analog voltage output

• Typical output: 0–10 V or -2 V to -18 V

• Capable of driving signals over long cable runs with minimal loss

• Compatible with DCS, PLC, or vibration monitoring systems

Technical Specifications

Applications

• Steam and gas turbines for shaft vibration and thermal expansion monitoring

• Centrifugal compressors for axial thrust and bearing clearance tracking

• Large pumps and fans for early detection of imbalance or misalignment

FAQ

Q: Can the sensor be replaced without recalibration?
A: Yes, the system is designed for interchangeability; replacement probes or converters typically require minimal recalibration.

Q: What materials can the sensor measure accurately?
A: Conductive metals such as carbon steel, stainless steel, and 42CrMo4 are ideal. Calibration must match the target material for precision.

Q: Is the system suitable for hazardous environments?
A: Yes, the probe is ATEX/IECEx certified for use in Ex zones.

Q: Can this system capture high-frequency vibrations?
A: Yes, the CON021 converter and PR6423 sensor together can measure high-frequency shaft vibrations for early fault detection.
