With the InfraRail, IRCON has successfully combined a signal conditioner and two-wire transmitter in one modular DIN-rail infrared thermometer. Now, you can integrate temperature measurement with other relays and signal conditioners already on your process line. The InfraRail infrared thermometer can be wired directly into any existing 24 volt dc power supply or can be supplied by a power supply ranging from 16 to 40 volts.

• Economical Miniature Sensing Head
• Convenient, standard DIN-rail mounting
• 4-20 mA two-wire signal conditioner/transmitter
• Typical uses: OEMs and user furnace, induction heating, steel and glass applications

BASIC SYSTEM- Consists of one temperature sensor, electronic module, 12 feet (4 meters) of interconnecting cable and connectors, and one detailed operations manual. Complete specifications and descriptions are shown in Catalog DN-08.

This modular, signal conditioner/ transmitter combination with analog output includes on-board signal processing circuitry and controls that make it easy to correct or adjust Emissivity and/or Response Time. In addition, the Peak-Picker function allows for accurate temperature measurement when measuring an intermittent target. With three distinctly different types of sensors, the InfraRail system can adapt to virtually any temperature measurement challenge from 700 to 5000°F (375 to 3000°C). All temperature sensor heads have NEMA 4 (IP 66) rated housings. And because these sensors are powered by internal photovoltaic cells, they require no special power sources.

Choose the Type "E" miniature fixed focus lens temperature sensor for economy and basic sensing requirements. With a non-sighted focus at 30" (762mm), the Type "E" sensor measures temperatures from 1400 to 5000°F (800 to 3000°C). This sensor is only 1.25" diameter by 4" length.

Choose the Type "S" thru-the-lens, single lens reflex (SLR) focusable optics temperature sensor for more discriminating sensing requirements where pinpoint focus and aiming are essential. These sensors are available with InGaAs detectors for lower temperature applications down to 700°F (375°C) or silicon detectors for higher temperature applications from 1000 to 5000°F (550 to 3000°C).
