Fiber optic pyrometer CellaTemp® PA 41

with LED displayRS485USB

Description
The CellaTemp® PA 41 is a digital two-colour pyrometer with a fibre optic cable for measuring temperatures between 700 and 3,000 °C. The two-colour pyrometer is equipped with a separate optical measuring head and a fibre optic cable. The fibre optic cable and measuring head are insensitive to interference from electromagnetic radiation and can be used in ambient temperatures up to 250 °C without cooling. The variant with separate optical measuring head offers advantages in confined spaces.

Special features

• Measuring ranges 700 to 3,000 °C
• Focusable interchangeable lenses for exact adjustment of the measuring distance
• Broadband anti-reflective precision lenses
• Short measuring wavelengths
• LED display can be read from a great distance
• Test current output for the diagnostic function
• Standard feature: analogue output and USB/RS 485 interface
• Measuring head and fibre optic cable heat resistant up to 250 °C
