Application Overview
The document discusses the temperature measurement of small objects, such as filaments in lamps and tubes, using panorama pyrometers. This measurement is crucial for assessing radiation characteristics, studying aging effects, and controlling heating systems.

Intensity Comparison Pyrometer
Historically, accurate temperature measurements of small objects were achieved using intensity comparison pyrometers. These devices require manual adjustment and are less affected by changes in emissivity, allowing for accurate measurements even from a distance. However, they are not suitable for automatic heating system control.

Electronic Pyrometers
Modern electronic pyrometers offer automatic temperature measurement with high spatial resolution. They use broadband-corrected multi-lens systems to ensure precise measurement alignment. These devices can continuously record data for analysis, aiding in the study of aging effects and radiation characteristics.

Solution: CellaTemp PA 43
The CellaTemp PA 43 is a two-color panorama pyrometer designed for small object measurement. It features a rectangular measurement area, making it easier to adjust and providing reliable measurements. The device offers over 40 optical variations with different lenses, suitable for objects as small as 0.1 mm. A special calibration curve is available for tungsten measurements.

Technical Specifications
The document provides detailed technical data for various models of the PA 43, including sighting aids, measuring ranges, and focal ranges. The pyrometer can be equipped with through-the-lens sighting, laser, or color camera options.

Accessories and Support
Available accessories include mounting brackets, angles, and supplementary lenses for smaller measurement areas. The document also lists contact information for sales and service centers worldwide.
