SharpEye 20/20R

Product catalog summary

Overview: The SharpEye Single-IR Optical Flame Detector (20/20R) is designed for early detection of flaming fires involving organic materials. It features advanced flame analysis tools and a cost-effective design, providing high sensitivity to CO2 emissions at 4.4 microns while minimizing false alarms from environmental IR sources.

Applications: This detector is suitable for various industries including automotive, chemical, oil & gas, onshore refineries, paint manufacturing, petrochemicals, pharmaceuticals, power generation, printing, tank farms, warehouses, and waste disposal facilities.

Main Features: Key features include sensitivity selection, user programmable configuration, immunity to false alarms, automatic and manual built-in tests, standard 4-wire connection, 4-20mA sink or source configuration, RS-485 interface, a minimum MTBF of 100,000 hours, a 3-year warranty, and ATEX & Gost K approvals.

Outputs: The detector provides relay outputs for alarms and faults, with specific current configurations for fault, normal, warning, and alarm states. It includes an RS-485 communication link for integration with computerized controllers.

Electrical Specifications: Operating voltage ranges from 18-32 VDC with a maximum power consumption of 200mA in alarm mode. It features electrical input protection and electromagnetic compatibility, marked with CE.

Mechanical Specifications: The detector is housed in a heavy-duty aluminum or optional stainless steel enclosure, meeting environmental standards for humidity, salt & fog, vibration, mechanical shock, and temperature extremes. It is water and dust resistant per IP66 and IP67 standards.

General Specifications: The detector operates within a spectral response of 4.2-4.5µm, with a detection range up to 50 ft for gasoline fires. It has a typical response time of 5 seconds, adjustable time delay, and a 90° field of view. It operates in temperatures from -40°F to 160°F and can be stored at temperatures as low as -65°F.

Hazardous Area Approvals: The detector is approved for use in hazardous areas with ATEX certifications.

Accessories: Available accessories include a fire simulator and a swivel mount.
