IRCON's Fiber Optic InfraRail GT Infrared Thermometer offers
the powerful features and affordable price of the standard InfraRail
Infrared Thermometer, along with the flexibility and
ruggedness provided by an temperature sensor using fiber
optics. The InfraRail GT's unique focusable reimaging
lens sensor assembly and fiber optic cable offer the opportunity
to sight on targets where direct sighting is impossible
or, as in the case of glass furnaces, where extremely
high ambient temperatures are present.
The Fiber Optic InfraRail GT is used to measure temperatures
of the crown, side walls, breast wall, checkers and
molten glass temperature in the furnace, forehearth,
and runners.

APPLICATIONS - Glass temperature measurement in the furnace, forehearth,
and runners.
Temperatures of the breast wall, checkers, bridge
wall, and crown.
INFRARAIL GT INFRARED THERMOMETER COMPONENTS :
The Fiber Optic InfraRail GT assembly consists of:
- InfraRail DIN-rail mounted Signal Processor with
response time adjustment, digital emissivity setting, peak picker,
and 4 to 20 mA linear output
- Fiber Optic Infrared Sensor
- 25ft (7.6m) of Fiber Optic Cable
- Focusable Reimaging Lens
- Model AAQ-1 Quick-Release Air Purge Assembly
- Model MB-2 Angle Mounting Bracket
- Model SI-12 Inconel Sight Tube (12in.[305mm])
Optional accessories may be purchased to replace those
supplied with the InfraRail GT Infrared Thermometer:
- Model SI-24 Inconel Sight Tube (12in.[610mm])
The InfraRail IR sensor operates at a 0.7 to 1.0 µm
wavelength. The sensor is a rugged, inherently stable
silicon photodiode with proven performance for over
40 years on glass furnace installations. The signal
processor can be mounted up to 1000 ft (300 m) from
the sensor and requires a simple two-wire shielded cable
for transmitting the sensor signal to the indicator.
The Reimaging Lens has a focal range of 10 in. to infinity
(254 mm to infinity). Most components are interchangeable
for easy routine maintenance. For more details, refer
to InfraRail Catalog DN-08
