Pyrometer without display CellaTemp® PR 11

°CIO-Linkanalog output

Product description:
The CellaTemp® PR 11 is a smart infrared thermometer for fast, non-contact and wear-free temperature measurement from a safe distance in the temperature range between 0 and 1,000 °C.

Special features:

• Compact infrared pyrometer with stainless steel housing
• Standardised, fieldbus-independent IO-Link interface
• Analogue output 0/4 - 20 mA (linear, switchable, scalable)
• Large measuring ranges with high temperature resolution
• High optical resolution and measurement accuracy due to broadband anti-reflective precision lenses
• Universally configurable switching output
• Simple mounting via M30 central thread
