Introduction to Part 330171-00-15-20-02-05
The 330171-00-15-20-02-05 is an industrial vibration transmitter designed for continuous condition monitoring of rotating machinery. It measures the overall vibration velocity (in mm/s RMS or in/s RMS) of machine bearings or housings and converts it into a standardized, loop-powered 4-20 mA analog signal. This two-wire device is engineered for reliability in harsh industrial environments, featuring a sealed, stainless-steel housing to withstand dust, moisture, and corrosive atmospheres. It provides a direct and reliable signal for plant control and monitoring systems to enable predictive maintenance and prevent unplanned machine downtime.

| IP Rating | IP67 | Dust-tight and protected against temporary immersion. |
Application Scenarios
This vibration transmitter is a key component in predictive maintenance programs, providing continuous data on machine health to avoid unplanned downtime.
Motor and Fan Monitoring: Permanent monitoring of vibration on motors, centrifugal fans, and blowers in HVAC systems, power plants, and manufacturing facilities.
Pump Bearing Protection: Detecting bearing wear, imbalance, and cavitation in critical centrifugal and reciprocating pumps in water treatment and chemical processing.
Compressor Condition Monitoring: Monitoring overall vibration on air and gas compressors to detect mechanical issues early, preventing severe damage.
Integration into DCS/PLC Systems: The 4-20 mA output allows for simple connection to Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC) for plant-wide asset monitoring and alarm generation.
Preventive Maintenance Systems: Serving as a fundamental sensor in a Condition-Based Maintenance (CBM) strategy, enabling maintenance to be performed based on actual machine condition rather than a fixed schedule.
