Product Overview
The Emerson PR6423-003-030-CN is a high-precision eddy current sensor for critical turbomachinery applications. Moreover, the CON021 signal converter processes sensor outputs for radial and axial shaft displacement, position, eccentricity, and speed. In addition, this combination provides robust and reliable measurement for turbines, compressors, pumps, and gearboxes. Its compact and rugged design supports installation in industrial environments with extreme vibration and temperature ranges.
Key Features & Functional Highlights
- Non-Contact Measurement: Accurately detects radial and axial shaft displacement without physical contact.
- High Precision Sensor: Linear measurement range of 2 mm, deviation ≤ ±0.025 mm.
- Signal Conversion: CON021 converts raw sensor data into standardized output signals with <1% linearity error.
- Environmental Tolerance: Sensor operates -35°C to +180°C, converter -30°C to +100°C.
- Robust Mechanical Design: IP66-rated sensor, stainless steel case, PTFE cable, and Lemo connector.
- High-Frequency Response: Signal converter frequency range 0–20 kHz with <15 µs rise time.
