CO233/A – Carbon Monoxide Gas Sensor with Display

Gas Detection

The CO233/A is Carbon Monoxide (CO) gas sensor with display for detection of Carbon Monoxide (CO). The sensor is compatible with the complete range of Duomo conventional gas controllers. It features a Time weighted average (TWA) feature that can indicate when gas levels have been over lower levels for a set time periods.

Product Details

  • Autosetting feature for calibration and Diagnosis
  • Preset to TWA and STEL Standards
  • 6 Colour Display for increased visibility
  • IP65 Protection
  • 4-20mA Industry Standard Output
  • Conventional GS or BX Control Unit Compatible
  • EN50270 & EN45544-1-3 Compliant

The CO233/A is a gas sensor for detection of Carbon Monoxide (CO) gas. A 4-20mA signal output is sent to any one of the Duomo controller panels listed. Furthermore the autosetting function keeps maximum detection accuracy at any time.

The 6 colour display informs the user of the status and CO levels. For example the Short term exposure limit (STEL) over 15 minutes and the time weighted average (TWA) over 8 hours. These levels are constantly tested and the display changes accordingly. 300ppm activates the main alarm relay. Another key point is the 0-300ppm linear output conforms to the 4-20mA standard. Also the CO100Ar is a version without the display. In addition to this the CO100P is set up for use in car parks.

According to the principle of accumulation, could also be toxic. The sensor is EN50270 & EN45544-1-3 compliant.
