The Marathon FA Fiber Optic Temperature Sensor consists of a rugged fiber 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-fiber optic thermometers. The assembly accommodates a small bend radius for threading through tight spaces.
Marathon FA thermometers maintain high accuracy (± 0.3% of temperature) and fast response time of 10 mSec over the ambient operating temperature range from 0º to 60ºC (32º to 140ºF). The fixed-focus optical head consists of a small stainless steel cylindrical housing and lens assembly. The optical head accommodates an air-purge accessory to prevent lens contamination and the fiber optic cable is protected by metal armor.
The Marathon FA Fiber Optic Temperature Sensors include Raytek DataTemp Multidrop software to enable easy and consistent installation, configuration and data capture.
