Introduction
The part number 9200-01-05-10-00 refers to a specific configuration of a Vibration Transmitter from the well-known EPI (Electro-Physical Instruments) 9200 Series or a compatible product line. This device is a cornerstone for basic machine condition monitoring.
It is a 4-20 mA, two-wire loop-powered vibration transmitter that measures casing vibration on industrial machinery. It integrates a robust accelerometer with sophisticated electronics to produce a standardized analog output signal that is directly proportional to the overall vibration velocity (e.g., in mm/s or in/s RMS). This simple and reliable signal is designed for direct integration into Programmable Logic Controllers (PLCs), Distributed Control Systems (DCS), and other plant monitoring systems, enabling continuous health assessment and immediate alarm generation.

Application Scenarios
This type of 4-20 mA transmitter is a workhorse for cost-effective, continuous monitoring across a wide range of industries. Its key application scenarios include:
Continuous Protection of Critical Assets:
Pumps, Fans, Blowers, and Motors: Permanently installed on the bearing housings to provide a continuous, real-time vibration signal. This allows control systems to trigger alarms or automatic shutdowns if vibration levels exceed pre-set limits, preventing catastrophic failure.
Plant-Wide PLC/DCS Integration:
Simplified System Integration: The universal 4-20 mA analog signal is wired directly into a PLC or DCS analog input card. This makes it ideal for replacing basic mechanical switches and for greenfield installations where simple, reliable monitoring is required for hundreds of machines.
Predictive and Condition-Based Maintenance:
Trending Machine Health: The output provides an overall velocity RMS value, which is an excellent parameter for tracking the general mechanical condition of a machine over time. Maintenance teams can use the trending data to schedule repairs before a failure occurs, moving from reactive to proactive maintenance.
General Purpose Machinery Monitoring:
HVAC Systems, Conveyors, Mixers, and Compressors: Used extensively in commercial and industrial applications where the cost and complexity of a full vibration analysis system are not justified, but reliable oversight of machine health is essential for operational continuity.
