Flame Detectors Provide Fast and Accurate Detection

Simtronics (USA), an IST company, have introduced their MultiFlame DF-TV7 series flame detectors that provide fast and accurate detection of hydrocarbon fires while ensuring reliable false alarm immunity. Available in Multispectral IR (IR3) and UV/2IR versions; both are housed in a rugged 316 stainless steel enclosure, approved to ATEX, CE, and IECEx global standards, and certified and suitable for use in SIL2 applications.

The DF-TV7-V flame detector is based on a multi-infrared spectrum (IR3) technology that provides the longest distance-to-detection on the market (260 ft for n-Heptane), is highly sensitive to fire and is ideal for use in dirty environments and for smoky fires. The DF-TV7-V flame detector uses combined ultraviolet/infrared (UV-2IR) optical technology that provides industry-leading immunity to false alarms based on the two IR channel design. Both solutions lead to a very efficient false alarm rejection while keeping optimum sensitivity to fire.

MultiFlame detectors can be configured to communicate with a wide range of fire panels, controllers, and PLCs and offer HART 7 and Syntel (Lonworks) protocols for addressable event monitoring. The devices come standard with a configurable 4-20mA or 0-22mA (PLC) output, two configurable alarm relays, and two detector status LEDs.

All MultiFlame detectors are equipped with a continuous optical lens auto-check to ensure that the optical path is clear and that the detector functions properly. Sensors can be replaced easily in the field without removing any cable glands. Devices are easy to test and configure using a TLU wireless handheld unit that is approved for use in hazardous areas. The TLU can also be used for wireless testing of the optical and output circuits.
