Epro PR6423/011-010 Eddy Current Displacement Sensor

Configured for monitoring shaft displacement, vibration, and position in rotating machinery, the Epro PR6423/011-010 (PR6423 Eddy Current Displacement Sensor) provides direct physical/electrical execution. It operates as an inductive non-contact transducer coupled with a CON021 signal converter to detect physical gap variations across high-speed rotating shafts. The sensor converts high-frequency electromagnetic field modulations into calibrated voltage outputs for integration into machinery protection frameworks.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

When integrated into process control platforms via the CON021 signal conditioning module, raw dynamic gap modulations undergo precise continuous signal conversion. Multi-channel input processing units incorporate galvanically separated paths to establish complete channel-to-channel isolation. This isolates individual signal loops, preventing ground noise propagation and dynamic cross-talk across multi-axis bearing monitoring setups in API 670 compliant machinery protection networks.

Frequently Asked Questions

Q: What power supply voltage is required to power the CON021 signal converter loop?

A: The CON021 signal converter operates on a nominal DC power supply input ranging from -23 VDC to -32 VDC.

Q: How does the system handle high-speed shaft vibration dynamics?

A: The PR6423/011-010 sensing element paired with the CON021 converter supports a frequency response up to 20 kHz, capturing both slow static position shifts and high-frequency dynamic vibrations.

Q: Is the PR6423/011-010 system compliant with API 670 standards?

A: Yes, the sensor and converter system meets API 670 standards for non-contact shaft displacement and vibration monitoring in industrial machinery protection applications.

Field Installation Guidelines

• Mechanical Thread Engagement: Hand-thread the sensor body into its mounting fixture, ensuring a minimum of 5 full mechanical threads of engagement before locking the jam nut.
• Gap Voltage Offset Calibration: Adjust physical probe insertion depth during static machine rest while checking the DC output voltage at the CON021 converter terminals to set the linear midpoint bias voltage.
• Cable Protection & Minimum Bend Radius: Route coaxial cabling inside flexible metallic conduit to protect against physical degradation. Maintain a minimum bend radius of 25 mm to prevent coaxial dielectric damage.
• Shield Grounding Discipline: Connect the outer cable shield strictly to a single point at the CON021 chassis ground to prevent ground loop noise interference.
