95DSS3-1CEX Fireye Scanner

Overview

The Fireye 95DSS3-1CEX InSight II is a microprocessor-based, integrated flame scanner designed to detect ultraviolet (UV) and infrared (IR) radiation from combustion flames. As part of the InSight II family, it integrates flame detection, amplification, safety determination, and flame switch functions into a single detection head, eliminating the need for a separate remote amplifier. This specific model features a standard flame-proof hazardous area housing with internal terminal blocks for cable connections and includes the 95DISP-1 display for local monitoring and configuration.

Features

• Dual sensor technology utilizing both solid-state infrared and ultraviolet sensors for comprehensive flame monitoring.
• Integrated design combines detection and amplification into one compact unit to interface directly with burner management systems.
• Two independently adjustable flame relays and a dedicated fault relay for enhanced safety and control.
• Electronic self-checking capability ensures continuous operation without the need for a mechanical shutter.
• Auto-configuration and “Auto Learn” functions for simplified setup and optimized flame discrimination.
• Advanced modulation frequency selection with 21 options to effectively distinguish the target flame from background radiation.
• Multiple memory files (up to 4) allow for different settings for various fuels or firing rates.

Specifications

• Power Requirement: 24 VDC.
• Output Signals: Two 4-20 mA analog outputs representing flame signal strength.
• Housing: ATEX/IECEx approved “CEX” explosion-proof housing (Ex d IIC T6).
• Environmental Rating: NEMA 4X, IP66.
• Weight: Approximately 7.1 lbs (3.22 kg) for the CEX model.
• Mounting: 1-inch NPT or BSP threaded connection with an integral heat-insulating insert.
• Safety Rating: SIL 3 certified for high-integrity safety applications.

Applications

The 95DSS3-1CEX is ideal for industrial and commercial multi-burner environments where reliable flame discrimination is critical. It is commonly used in power plants, refineries, and large-scale manufacturing facilities to monitor flames from various fuels, including natural gas, oil, and coal. Its explosion-proof rating makes it suitable for installation in hazardous areas where flammable gases or vapors may be present.
