Fibre-Optic Infrared Sensors

Add to Bookmarks
This product is no longer available.


The Marathon FA fibre optic temperature sensor consists of a rugged fibre optic cable plus optical head assembly connected to an electronics housing containing the detector, processing electronics, internal user interface/LED display, and termination connections for field wiring. These infrared sensors maintain targets in highly confined installations in harsh industrial environments, otherwise inaccessible by non-fibre optic thermometers. The assembly accommodates a small bend radius for threading through tight spaces.
