The BAPI BA/CO-D-BB is a Duct Mounted Carbon Monoxide Sensor that uses an aspiration tube for duct air sampling. This sensor provides great accuracy performance in electrochemical sensing even at low concentrations.
The sensor features 10 seconds backlit whenever a button is pushed and an LCD display for easy access CO reading. Also, the sensor uses ppm as the unit of measurement.
The carbon monoxide detection is up to 500 ppm. Also, it has field selectable outputs of 0 to 5, 1 to 5, 0 to 10, and 2 to 10 VDC and does have a 3-wire 4 to 20 mA output. The two SPDT Alarm Relay Switch setpoints are 25, 35, 50, 100, and 200 ppm CO concentrations. Monitoring made easy, with the LED indicator that displays different colors such as green, yellow, and red representing the unit's status.
