Two-color pyrometer CellaTemp® PA 40

with LED displaywith laser pointerRS485

Overview
The CellaTemp® PA 40 is a digital two-colour pyrometer for non-contact temperature measurement from 500 to 3,000 °C. The two-colour measurement method reduces sensitivity to interference from dust, vapour, dirty protective windows and changing target surfaces compared with single-colour pyrometers. Sighting options include through-the-lens aiming, a laser pilot light and an optional camera module for precise alignment.

Key features

• Measuring ranges: 500 to 3,000 °C (multiple segments)
• Focusable interchangeable lenses for exact adjustment of measuring distance
• Broadband anti-reflective precision optics with short measuring wavelengths
• Readable long-distance LED display and two status LEDs
• Test current output for diagnostics
• Standard outputs: analogue (0(4)-20 mA) and USB / RS 485 interface
