METRIX ST5484E-121-0512-00 ST5484E Series Seismic Velocity Transmitter in stock

The Metrix ST5484E-121-0512-00 is a self-contained, loop-powered seismic velocity transmitter designed for general-purpose vibration monitoring on rotating and reciprocating machinery. It integrates a piezoelectric accelerometer, signal integrator, RMS peak detector, and a 4-20 mA signal conditioner into a single robust package.

This model is specifically engineered to mount directly onto machine casings or bearing housings without requiring intermediate signal conditioning equipment, making it an ideal solution for integration with PLCs, DCS, and SCADA systems for simplified vibration monitoring strategies .

Key Features

All-in-One Design: Combines sensor and signal conditioner in one unit.

4-20 mA Loop Output: Provides a proportional signal for trending and alarming, compatible with standard industrial control systems.

Improved RFI/EMI Immunity: Enhanced circuit designs filter out noise from common sources like handheld radios .

Flexible Mounting: Available with various mounting stud sizes and options suitable for hazardous area installations (ATEX, CSA, etc.) depending on configuration.

Durable Construction: Features excellent moisture resistance; versions are rated up to IP67 (MIL connector version).

Understanding the Metrix ordering code ensures you get the exact configuration for your needs :

ST5484E: Product Family (Seismic Velocity Transmitter).

121: Full Scale Range (1.0 in/sec Peak).

0512: Configuration code for mounting thread, connector type, and approvals (specific to standard 1/4-28 UNF mounting stud with specific connector options).

Applications

The ST5484E series is ideal for continuous monitoring of industrial machinery where a full standalone monitoring system may not be warranted. Typical applications include:

Motors, Pumps, and Fans: Monitoring bearing health and imbalance.

Compressors and Gearboxes: Detecting wear and tear on rotating elements.

Reciprocating Machinery: General vibration trend analysis.

Rolling Element Bearings: Where shaft vibration transmits directly to the bearing housing.

Why Choose the ST5484E-121-0512-00?

This specific configuration (1.0 in/sec peak) offers the perfect balance of sensitivity and range for most standard industrial rotating equipment operating between 120 and 6,000 RPM. Its "In Stock" status ensures minimal downtime for critical machine health monitoring installations.
