UV/IR Wet Bench Flame Detector 3200/3300

Sierra Monitor’s 3200/3300 Series flame detector monitors for flames found in indoor applications, such as semiconductor wet benches, warehouses, and exhibition halls.

The 3200/3300 Series flame detector utilizes proven, stable ultraviolet and infrared technology to continuously monitor for flames in wet bench and commercial applications. It is an ideal solution for use in areas where short line of sight is a factor. Due to its compact size, it is also used for installation in certain production equipment.

The standard 3200/3300 module has a sealed polypropylene housing designed for protection from a wide variety of acids and solvents. The detector is rated over a wide operating temperature range for those applications where drying or heating elements are used or elevated temperatures may be experienced. Both models can easily adapt to most standard fire extinguishing systems and wet bench systems. In addition, 3200/3300 modules use state-of-the-art microprocessor controlled fire algorithms to recognize different types of flame signatures while rejecting common false alarms.

The UV/IR Flame Detector 3200/3300 is approved and certified by a variety of third party agencies, including FM and CSFM. These approvals and certifications assure our customers that we carry only the highest quality of products and performance.
