Raytek Marathon MR Series infrared sensor is ideal for measuring targets that are difficult to access using traditional non-contact sensors, especially in challenging high-temperature environments. This sensor has a high distance-to-spot ratio and is specifically designed to accurately measure targets that may be obscured by smoke, steam, particles, or smaller than the sensor’s viewing area.

Operating efficiently in ambient temperatures up to 315°C (600°F) with the ThermoJacket enclosure, the Raytek Marathon MR Series supports integration of up to 32 sensors in a single multidrop network. The included Raytek DataTemp Multidrop software simplifies installation, configuration, and data capture, making it suitable for various applications where precise and reliable measurements are essential.

  • steel and metals processing (foundry/forging operations & heat treating)
  • glass bending, forming, tempering, annealing, and sealing
  • paper processing (ink drying/curing & lamination)
  • plastics processing and thermoforming; and semiconductor processing
