CO – DUCT AND ROUGH SERVICE CARBON MONOXIDE SENSOR
BAPI’s Carbon Monoxide Sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. The Duct unit samples duct air using an aspiration tube. The Rough Service unit features a ventilated BAPI-Box and is ideal for parking ramps, equipment rooms and warehouses.
The sensor has field selectable CO ranges of 0 to 100, 0 to 200, 0 to 300 and 0 to 500 ppm. It also has field selectable outputs of 0 to 5, 1 to 5, 0 to 10 and 2 to 10 VDC as well as a 3-wire 4 to 20 mA output. The LCD shows the CO reading in ppm and is backlit for 10 seconds after any button push. Two independent SPDT alarm contacts switch at field selectable CO concentrations of 25, 35, 50, 100 and 200 ppm. A status LED is green when the measured CO is below the lowest relay setpoint. The LED turns red whenever an alarm relay is on.
An alarm timer holds the output relays on for a field selectable time 0 to 10 minutes after the CO level has fallen below 80% of setpoint.
