EIT 2.0™ Compact Sensors — High‑Reliability UV Detectors for Continuous On‑Line Monitoring

The EIT 2.0 Compact Sensor family represents a core component of EIT’s Online UV Monitoring Systems, engineered to deliver continuous, durable, and spectrally precise detection of ultraviolet intensity in industrial curing and processing environments where traditional handheld instruments are impractical or inaccessible. These sensors are specifically designed to support real‑time relative UV output tracking of broadband (mercury) and UV LED sources, enabling process engineers to detect gradual degradation, sudden changes, and trend drift in UV intensity that can compromise product quality and throughput.

Technical Precision & Industrial Durability

• Spectrally Tailored Detection: Compact Sensors are available in multiple bandwidths optimized for industrial sources — including mercury spectral bands (UVA, UVB, UVC, UVV) and LED L‑Bands (L‑365, L‑385, L‑395, L‑405) — ensuring that optical response closely matches the emission characteristics of the target source for reliable relative monitoring.

• Robust Design for Process Environments: Each sensor features a hermetically sealed optical path that resists contamination and degradation (solarization), enabling thousands of hours of operation in intense UV fields without measurable performance loss.

• Compact, Flexible Form Factor: Small, squared housing designs (e.g., CS‑1 with purge or CS‑2 height‑reduced) allow installation in tight, elevated, or restricted locations, including behind reflectors, within narrow ovens, or close to curing zones where full‑size instruments cannot be positioned.

• Optimized Aperture Selection: Internal aperture sizes are specified at the time of order based on source power, mounting geometry, and distance to the UV source, enabling engineers to fine‑tune detection sensitivity for high‑intensity or distant installations.

• High Temperature Capability: Designed to withstand elevated operating environments (up to ~100 °C for most bands, with specific limits for UVC and LED bands), Compact Sensors maintain integrity under industrial thermal stress.

System Compatibility & Process Integration

Compact Sensors are engineered to work in a 1:1 ratio with EIT signal conditioning and monitoring modules, including DIN Rail UV Intensity Monitors, enabling seamless integration into continuous process control systems. The 0–10 V or 4–20 mA analog outputs generated through these systems facilitate direct interface to PLCs, HMIs, and distributed control environments for real‑time alarms, trend capture, and quality reporting.

Optional EMI‑hardened variants further enhance performance in electrically noisy environments (e.g., microwave sources or high‑voltage power assemblies), reducing interference and ensuring signal fidelity in demanding industrial installations.

Solution‑Oriented Benefits for UV Process Control

The EIT 2.0 Compact Sensor portfolio provides a highly adaptable, industrial‑ready means of maintaining visibility into UV intensity that supports:

• Proactive Quality Assurance: Continuous relative intensity monitoring identifies source aging, coating contamination, or reflector fouling before product defects occur.

• Tight Process Window Control: Ideal for high‑speed web curing, multi‑lamp arrays, enclosed ovens, and applications where variability in UV output must be minimized.

• Integration with Automation: Analog output signals support automated alarm logic, trend logging, and SPC documentation without manual intervention.

• Flexible Deployment: Scalable across multiple zones, LED or broadband sources, and diverse industrial configurations where continuous UV tracking is critical.

EIT 2.0 Compact Sensors embody rugged, spectrally precise detection tailored for continuous UV monitoring — delivering reliable, solution‑oriented performance that empowers engineers to optimize curing consistency, reduce waste, and maintain quantifiable control in demanding industrial processes.
