Emerson PR6424/010-030 16mm Eddy-Current Contactless Sensor

Emerson PR6424/010-030 is a high-performance eddy-current displacement sensor engineered by EPRO (now part of Emerson) for non-contact measurement of dynamic and static phenomena on rotating machinery. As a critical component in turbine supervision and condition monitoring systems, this sensor is specifically designed to measure shaft vibration, radial and axial displacement, and eccentricity in harsh industrial environments .

Key Technical Specifications

The PR6424/010-030 operates on a 16mm probe diameter platform and utilizes a robust inductive measuring principle. It generates a high-frequency electromagnetic field to detect changes in the gap to a conductive target, converting physical movement into precise electrical signals . Below are the core specifications for this model:

Measurement Range: Designed for a linear range of approximately 2mm, suitable for radial vibration and axial position monitoring.

Sensitivity: Typically configured with a sensitivity output that matches standard monitoring systems like the MMS 6000 .

Target Material: Calibrated for conductive materials (standard steel 42CrMo4), ensuring accuracy in real-world turbomachinery applications .

Temperature Tolerance: Capable of operating in extreme conditions with a standard range of -35°C to +180°C, with the ability to withstand higher transient temperatures .

Rugged Construction: Features a stainless-steel housing and is resistant to pressure, oil, and aggressive media, meeting international standards such as API 670 for axial and radial shaft monitoring .

Decoding the Part Number: PR6424/010-030

Understanding the EPRO numbering system is crucial for proper selection:

PR6424: Identifies the series as a 16mm diameter sensor head, typically used with M16 x 1 threading for secure installation .

/010: This code usually specifies the probe cable length and configuration.

-030: This suffix defines the specific sensitivity and calibrated linear range of the sensor. It dictates the electrical scaling (e.g., V/mm) required for compatibility with the signal converter (like CON021).
