Sensor Induktif Emerson PR9350/02 AMS

Description

The Emerson PR9350/02 is a surface contact inductive sensor designed for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, pumps, and fans. This heavy-duty displacement transducer measures radial and axial shaft dynamic displacement, position, and eccentricity under tough environmental conditions. Operating on a carrier frequency principle with center-tapped windings, the PR9350/02 provides stable position tracking and high precision for industrial machinery protection and condition monitoring.

Features

• Surface contact inductive design optimized for shaft displacement and eccentricity tracking 
• Robust construction tailored to survive demanding and tough industrial environments 
• Supplied with a matching solenoid plunger featuring an integrated M3 threaded rod 
• Equipped with a reliable electrical interface utilizing an ITT Cannon connector 

Applications

• Radial and axial shaft dynamic displacement measurement 
• Turbomachinery shaft position and eccentricity monitoring 
• Critical protection loops for gas, steam, and hydro turbines 
• Structural or displacement monitoring on large industrial compressors, pumps, and fans

Installation Guidelines

• Use the integrated M4 fixing holes to securely mount the housing block to a stable reference point on the machine casing.
• Ensure proper mechanical alignment of the solenoid plunger with the M3 threaded rod during setup.
• Align the core slug to match dimension C (65.4 mm) relative to the sensor frame to reference the true nominal center or zero position.
• Verify that the carrier frequency of the driver electronics is configured between 3 and 5 kHz to preserve sensitivity and accuracy requirements.
