Infrared temperature sensor CellaTemp® PA 15

thermopilein metal housing0-10 V

Product overview:
The CellaTemp® PA 15 is a narrow-band, single-colour infrared pyrometer for near-surface temperature measurement on glass. The spectral sensitivity of 4.6–4.9 µm minimises influence from glass thickness or type and reduces sensitivity to atmospheric effects such as humidity changes.

Key features:

• Measuring range: 300 to 2,500 °C (configurable in segments)
• Focusable lenses for precise adjustment of measuring distance
• Broadband anti-reflective precision optics
• 4-digit red LED display readable at long distance
• Test current output for diagnostics
• Standard interfaces: digital I/O, two analogue outputs, USB and RS‑485

Versions / options:

• Versions: CellaTemp PA 15 AF 1 and CellaTemp PA 15 AF 2
• Typical ranges: AF 1 → 500–2500 °C; AF 2 → 300–1300 °C (version-dependent)
