Diligent Micro Controls offers Infrared Falme Sensor. Diligent Micro Controls offers Electronic Controllers, Electronic Control Systems & Electronic Control Relays for specific industrial applications. The Infra Red Sensor or Infra Red type IR-EYE-FV houses infra red element IRD1010 from M/s Satronics [now Honeywell] in strong aluminum holder. This holder has quartz window to guard against the environmental conditions in the furnace and also has cooling air adaptor to facilitate connection of cooling air supply. Sensing flame by detecting the infra red emission from the flame is especially effective when the view of the flame is obscured by dust or smoke such as the in coal fired burner or blast gas burner.
