Rosemount 644 RAI1Q4EL - 2-Wire Vibration Transmitter | Emerson
Product Description
Key Features
-
2-Wire, Loop-Powered Design: Simplifies installation and reduces wiring costs compared to 4-wire systems.
-
Dual-Parameter Output: Simultaneously provides overall vibration (Velocity) and high-frequency bearing condition (Acceleration via enveloped gPEAK).
-
Robust Construction: Features a rugged, NEMA 4X / IP67 rated housing, making it suitable for harsh industrial environments.
-
4-20 mA Analog Output: Ensures easy connection to most control and monitoring systems without additional hardware.
-
Velocity & Acceleration Measurement: Delivers comprehensive data for both general machine health and early-stage bearing fault detection.
The Rosemount 644 RAI1Q4EL is a robust, loop-powered vibration transmitter designed for continuous monitoring of critical industrial assets. It converts mechanical vibration directly into a standardized 4-20 mA output, enabling seamless integration with existing control systems (DCS/PLC) for predictive maintenance and machinery protection.
