The FM 3/8 is a highly sensitive spark and ember detector for protection against fire and explosion in industrial processes. It uses fibre optic cables to deal with high material temperatures (up to 500 °C) used in certain industrial processes. The detector reacts to the infrared range of light radiated by an ignition source. It is designed to be used in an environment free from ambient light.
The detector can be connected to every GreCon control console using a standard three core cable. A range of flexible mounting adapter options exist to suit any environment. The control console interfaces with the detector for monitoring of ignition sources within the process, the configuration of detection parameters and automated check of the detector optics’ correct function. Fibre optic cables in various lengths allow the detector to be situated remotely outside the high temperature area.
Key benefits
Highly sensitive detection of sparks and embers in high-temperature applications
Detection not dependent on temperature of ignition source
Highly reliable detection of ignition sources, even at high transport speed and load
Flush-mounted installation of detector optics for maximum life
VdS and FM approved - Dust Ex safety options available for ATEX and IECEx
