The BAPI BA/NO2-V-BB Rough Service Unit Nitrogen Dioxide Sensor is an excellent fit for equipment rooms, parking ramps, and warehouses. The sensor offers up to four NO2 field selectable ranges of 0 - 2.5, 0 - 5, 0 - 7.5, and 0 - 10 PPM. Field selectable outputs of 0 - 5, 1 - 5, 0 - 10, and 2 - 10 VDC, and a 3-wire 4 to 2mA output. It has two independent SPDT switch for alarm relay on Nitrogen Oxide field selectable 1.0, 2.5, 5.0, 7.5, and 10.0 PPM. Also, the sensor consists of a BAPI-Box enclosure and LED light indicator.
The BAPI NO2 Air Sensor is designed to provide great accuracy even at lower concentrations. When the NO2 has dropped below 80% of setpoint, the alarm timer holds the output relays on for 0,1, 5, or 10 minutes. This extra fan run time helps to eliminate NO2 presence. It features a sensor module that performs self-test. The sensor module is replaceable and has a lifespan of 7 years.
