The 1100 Series Infrared Thermometer is an accurate, reliable, and economical high temperature measurement device primarily used in the semiconductor industry. It provides a continuous, nonlinear, temperature-dependent output which can be used in conjunction with recording or controlling instrumentation. The optical components and silicon infrared detector are housed in a rugged, die cast, gasketed enclosure, allowing operation in the most severe industrial environments.

  • High Accuracy And Repeatability
  • Fully Automatic Temperature Compensation From 0 To 200°F (0 To 93°C)
  • Through-The Lens Sighting And Focusing
  • High Resolution Optics Provides For Measuring Of Objects As Small As 0.012" (0.3 Mm)
  • No Power Supply Required
BASIC SYSTEM - Consists of one Sensor, Calibration Module, 12 foot or 4 meter interconnecting cable, temperature verses output curve and detailed manual. Complete specifications and details are shown in PB-1100.

OPERATION

Every object emits infrared radiation as a function of its temperature. In the 1100 Series Pyrometer, an optical system spectrally selects the radiation from the object and focuses it onto a solid-state silicon detector. The detector generates an electrical signal proportional to the radiant intensity. The resulting nonlinear signal output provides a direct input for indicating and control devices. as shown in the picture, each Module is provided with a curve relating signal level with object temperature for its temperature range.

The 1100 Series Pyrometer utilizes the near end of the infrared spectrum, a narrow band centered at 0.9 micron. Operation in this spectral region overcomes the major sources of instrument error as follows:

  • Effects of atmospheric absorption bands such as water vapor and carbon dioxide are eliminated.
  • Errors caused by varying target emissivity are minimized.
  • Interference due to open clean flames is minimized.
A curve relating signal level with object temperature is provided for each Calibration Module supplied.
