METRIX ST5484E-151-132-02 ST5484E Series Seismic Velocity Transmitter in stock

The Metrix ST5484E-151-132-02 is a self-contained, loop-powered seismic velocity transmitter designed for reliable vibration monitoring on industrial rotating machinery. Part of the renowned ST5484E Series, this model integrates a piezoelectric accelerometer, signal integrator, RMS peak detector, and a 4-20 mA signal conditioner into a single robust housing. It mounts directly onto machine casings or bearing housings, eliminating the need for external signal conditioning equipment.

This unit is ideal for general-purpose vibration monitoring on pumps, motors, fans, compressors, and gearboxes, specifically optimized for machinery with rolling element bearings operating between 120 and 6,000 rpm.

Key Features

All-in-One Design: Combines sensor and transmitter in one package; outputs a proportional 4-20 mA signal directly to PLCs, DCS, and SCADA systems.

Hazardous Area Approved: Suitable for use in explosive environments with ATEX, CSA, and IECEx certifications (intrinsically safe).

Rugged Construction: Housed in durable 303 Stainless Steel with excellent moisture resistance (IP66/IP67 ratings depending on connection type).

Versatile Mounting: Standard ¼” NPT mounting stud for easy installation.

Polarity Independent Wiring: Features Metrix patented IPT® technology, allowing loop power to be connected without regard to polarity, reducing wiring errors.
