Description

The Siemens QRB1A-A033B40B flame sensor works in conjunction with burner automation, continuously monitoring the combustion of yellow flame in the visible spectrum of light. For systems with intermittent cycles, operating on liquid fuel.

Features

  • Compact design, two-wire cable, material – thermoplastic.
  • The light-sensitive element of the device is a photoresistor.
  • Guide spring for accurate centering relative to the flame.
  • Side, front measurement.
  • Sensitivity up to 600 nm.
  • Easy installation in the burner (requires a single hole with a cross groove).
  • Reliable fixation thanks to a soft plastic insert and seals.
  • Power cable length 330 mm.
  • Dust and moisture protection according to IP 40 standard.
  • Operating temperature -20...+60 °C, humidity <95 %.
  • For LO140...280 TN.

Siemens QRB1A-A033B40B sees the spectral part of the radiation from extraneous light sources. Therefore, appropriate measures must be taken to ensure the safe operation of the burner.
