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.

FEATURES

• Response times as fast as 0.0015 second
• 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.
