總覽:

The Simtronics DF-TV7–V is a combined ultraviolet / infrared flamedetector offering excellent flame detection whilst maintaining outstanding false alarm immunity.

The MultiFlame DF-TV7–V is designed to respond to unwanted hydrocarbon fires, whilst maintaining a high degree of false alarm immunity. 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.

The device offers a wide range of output options, as standard and is suitable for use in SIL 2 applications. The detector 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. The TLU can also be used for wireless testing of the optical and output circuits.
