Measurement & Monitoring / Online Monitoring Systems

Measurement & Monitoring | Online Monitoring Systems

EIT’s On-Line Systems provide continuous UV intensity feedback for precise process control. Ideal for challenging applications where traditional radiometers are impractical. Detect changes in UV output, optimize curing, and reduce scrap.

EIT On-Line System Components:

The system comprises two key components:

EIT Compact Sensor: An extremely durable, sealed sensor designed for harsh UV environments. Available for both LED and broadband UV sources. EIT and our representatives can assist you in selecting the optimal optic response, housing shape, aperture size, and mounting location based on your specific UV source and application.
EIT DIN Rail Signal-Conditioning Unit: Works in conjunction with the Compact Sensor to provide a 0-10 volt or 4-20 milliamp signal proportional to real-time UV intensity. This signal integrates seamlessly with PLCs or displays for easy monitoring. The DIN Rail unit also enables configurable low-limit alarms and relay control for automated process adjustments.

Why Choose EIT On-Line UV Monitoring?

EIT On-Line Systems are the ideal solution for situations where:

Space is limited: Compact sensors fit where radiometers can’t.
Obstacles are present: Monitor UV intensity despite obstacles like arms, rollers, or blades.
Sources are inaccessible: Monitor enclosed, hard-to-reach, or high-mounted UV sources.
Multiple sources are used: Track the performance of multiple UV sources simultaneously.
Production speeds are high: Real-time monitoring eliminates manual measurements on fast-moving lines.
UV conditions fluctuate: Monitor rapid changes in UV intensity due to off-gassing or contamination.
Product quality is critical: Prevent costly scrap by detecting subtle shifts in UV output.
Continuous validation is required: Maintain consistent UV conditions for critical processes.
Process windows are tight: Ensure UV intensity remains within precise parameters.

Applications:

EIT On-Line Monitoring Systems are used in diverse industries, including:

Web presses
Fiber optic draw towers
Hard drive manufacturing
Printing
Medical applications

Benefits of Real-Time UV Monitoring:

Early Issue Detection: Identify gradual (source aging) or sudden (equipment malfunction) changes in UV intensity before they impact product quality.
Proactive Maintenance: Schedule maintenance based on real-time data, minimizing downtime and maximizing efficiency.
Improved Product Quality: Ensure consistent UV dosage for optimal curing, bonding, and other UV-dependent processes.
Reduced Scrap & Rework: Prevent costly errors by monitoring UV intensity and taking corrective action promptly.
Increased Profitability: Optimize production processes and minimize waste for improved bottom-line performance.

Relative vs. Absolute Intensity:

The On-Line Monitoring System measures relative intensity, allowing you to track changes in UV output over time. While it doesn’t provide an absolute (W/cm²) value, it effectively detects both gradual (source aging) and sudden (equipment malfunction) changes in UV intensity, enabling timely intervention. It can be used as the sole means of UV process control or in conjunction with an EIT NIST-traceable UV radiometer.
