Product catalog summary
Overview: The document provides technical specifications and operational details for the stationary pyrometer type R271, designed for contactless temperature measurement in high ambient temperatures. This technology is advantageous as it allows the sensor to be mounted near the measured object without requiring cooling, leading to cost reductions.
Specifications:
  • Measurement Range: 0...250 °C (32...482 °F)
  • Emission Factor: 0.1...1
  • Transmission Factor: 0.1...1
  • Ambient Conditions: 20...250 °C (68...482 °F)
  • Output Signal: 4...20 mA, linear
  • Measuring Accuracy: ≤ 2% of measurement range
  • Response Time: t 0.9 = 6 s (without damping)
  • Power Supply: DC 12...30 V, max. 23 mA
  • Protection Type: IP 65
  • Casing Material: Aluminium diecast, Stainless steel
  • Weight: 350 g (Aluminium), 1200 g (Stainless steel)
  • Cable Length: 5 m
Features:
  • Small design allows mounting in narrow spaces.
  • Silicon window seals the optical system against the environment.
  • Communication via HART® protocol.
  • Suitable for high ambient temperatures with a protected connection cable.
Applications: The pyrometer is suitable for various applications such as continuous furnaces for lacquer drying, textile and paper drying, especially where the measured object has low heat conductivity, is in motion, or requires quick measurement.
Operational Conditions:
  • Permissible Working Temperature: 0 ... +70 °C
  • Permissible Storage Temperature: -10 ... +70 °C
  • Climatic Class: KWS in accordance with DIN 40040
