METRIX ST5484E-151-132-00 Seismic Velocity Transmitter

Product Description

The Metrix ST5484E-151-132-00 is a high-performance, self-contained seismic velocity transmitter designed for continuous vibration monitoring of rotating machinery. This "loop-powered" sensor converts mechanical vibration into a standard 4-20mA analog signal, which can be fed directly into a PLC, DCS, or SCADA system. By eliminating the need for a separate signal conditioner, the ST5484E simplifies installation and reduces overall system costs.

Constructed with a rugged 316 stainless steel housing, this model is engineered to thrive in the harshest industrial environments. This specific configuration includes an 8200 conduit elbow, making it fully explosion-proof and certified for use in Hazardous Areas (Class I, Div 1). Whether monitoring cooling tower fans, pumps, or motors, the ST5484E-151-132-00 provides the reliable, real-time data necessary for effective predictive maintenance and machinery protection.

Application Scenarios

The ST5484E is a versatile solution for general-purpose machinery monitoring:

• Motors & Pumps: Detecting early-stage bearing wear or unbalance in industrial fluid handling.

• Cooling Towers: Monitoring fan vibration levels to prevent catastrophic structural failure.

• Centrifuges: Providing a high-speed vibration "trip" signal to protect critical processing equipment.

• Blowers & Fans: Continuous monitoring in chemical plants and refineries where explosion-proof ratings are mandatory.
