Emerson PR9376/010-001 EPRO Hall Effect Speed/ Proximity Sensor

Description

The PR9376/010-001 is a non-contact Hall effect sensor engineered for precise speed or proximity measurements in critical turbomachinery applications. This sensor is designed for use with steam, gas and hydro turbines, compressors, pumps, and fans. It provides a frequency-based output proportional to the rotation of a gear or target, ensuring reliable performance in demanding industrial environments.

Features

• Non-contact measurement technology
• 1 AC cycle per revolution/gear tooth output
• High frequency operation up to 12 kHz
• Integrated armored cable for enhanced mechanical protection
• Open cable end configuration
• Robust sealing for harsh industrial conditions

Applications

• Steam and gas turbine speed monitoring
• Hydro turbine rotation measurement
• Compressor and pump speed sensing
• Critical turbomachinery proximity detection

Installation Guidelines

• Ensure the target surface material consists of magnetic soft iron or steel (non-stainless steel).
• Align the sensor to maintain the specified air gap (1 mm for Module 1, 1.5 mm for Module >= 2) from the trigger mark or spur wheel.
• Utilize the integrated armored cable to prevent mechanical damage in vibration-prone areas.
• Ensure power supply remains within the 10 to 30 VDC range to maintain output signal integrity.
