Physical Characteristics:

Cable Length: 8 meters (1+7m), with Lemo-type connectors.
Case Thread Length: 155 mm
Weight: Approx. 100 grams

Application Areas:

This sensor is used in turbines, compressors, gearboxes, pumps, and fans to monitor:

Radial and axial shaft displacement.
Shaft eccentricity.
Speed, critical in machinery health monitoring.

CON021 Eddy Current Signal Converter

The CON021 Signal Converter works in tandem with the PR6423 sensor to convert the eddy current sensor’s analog signal into a usable form for analysis and control systems.

Key Features:

Dynamic Performance:
- Frequency Range: 0 to 20,000 Hz (-3 dB), supporting high-speed machinery applications.
- Rise Time: Less than 15 µs, enabling rapid response to changes in shaft position or dynamics.
Power Requirements:
- Supply Voltage Range:
  - -23V to -32V (with output range -4V to -20V)
  - -21V to -32V (with output range -2V to -18V)
Environmental Specifications:
- Operating Temperature: -30°C to +100°C (-22°F to +212°F)
- Vibration Resistance: 5g @ 60Hz at 25°C
- Protection Class: IP20, providing basic protection in controlled industrial settings.

Compatibility:

Specifically designed for use with PR6422, PR6423, PR6424, PR6425, PR6426, and PR6453 sensors.
PR6425 sensor requires an extended range converter, such as CON021/91x-xxx.

Combined System Benefits:

Accurate Shaft Monitoring: The combination of the PR6423 sensor and CON021 converter provides precise monitoring of shaft displacement and position, helping to prevent mechanical failures in critical machinery.
High-Speed Applications: The wide frequency range (up to 20 kHz) and fast rise time of the converter make this system ideal for high-speed turbomachinery.
Environmental Resilience: The sensor’s robust construction (IP66) and high-temperature resistance ensure reliability in harsh operating environments, while the converter operates in a wide temperature range, making it versatile across industries.

Example Configuration:

PR6423/00E-030: An 8mm Eddy Current Sensor with M10x1 threading, 155mm case length, 1+7 meter cable length, no armor, and a Lemo connector.
CON021 Converter: Provides signal conversion from the sensor to the control system, ensuring accurate monitoring and control of shaft dynamics.

This system is particularly well-suited for applications such as:

Steam turbines.
Gas turbines.
Hydro turbines.
Compressors.
Pumps.
Industrial fans.

Together, the PR6423/00E-030 sensor and CON021 converter offer a reliable and high-performance solution for monitoring and protecting critical turbomachinery.
