Rosemount 644 RAI1Q4EL - 2-Wire Vibration Transmitter | Emerson

Product Description
The Rosemount 644 RAI1Q4EL is a robust, loop-powered 2-wire vibration transmitter designed for continuous machinery health monitoring in demanding industrial environments. It provides a cost-effective solution for predictive maintenance by converting mechanical vibration into a standardized 4-20 mA output for seamless integration with DCS or PLC systems. This model simultaneously monitors overall vibration velocity (4.5 Hz - 1,000 Hz) and high-frequency acceleration (gPEAK), offering a dual-parameter view of machine health for both general mechanical issues and early-stage bearing faults. Housed in a NEMA 4X/IP67 rated enclosure, the transmitter is built to withstand harsh conditions. With a simple 1/4-28 UNF stud mounting and a dynamic range of 0 to 1.0 in/s, it is an ideal choice for protecting critical assets like pumps, motors, fans, and compressors.

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.
