Bapi BA/AQX-E Dual Channel CO2 Sensor 0-5000 Ppm

Product Description

The BAPI BA/AQX-E is a dual-channel carbon dioxide sensor designed for continuously occupied spaces where reliable CO2 monitoring is essential for indoor air quality (IAQ) management. It outputs a 0 to 5 volt analog signal corresponding to a measurement range of 0 to 5,000 parts per million (PPM) of CO2. The dual-channel design supports simultaneous monitoring across two zones or provides redundancy in critical applications. Building automation contractors, HVAC controls technicians, and facilities engineers typically specify and install this sensor as part of a demand-controlled ventilation or IAQ monitoring system.

The BA/AQX-E is suited for a wide range of continuously occupied environments including greenhouses, laboratories, food and beverage facilities, parking garages, and agricultural settings, as well as general IAQ monitoring in commercial and institutional buildings. Its voltage output integrates directly with building automation systems (BAS) and controllers that accept 0 to 5V analog inputs, making it a practical fit for new construction and retrofit controls projects alike.

Key Features

• Dual-channel sensing supports two-zone monitoring or redundant measurement in a single device
• 0 to 5,000 PPM measurement range covers typical ambient and elevated CO2 levels in occupied spaces
• 0 to 5V analog voltage output for direct integration with BAS and DDC controllers
• No onboard display keeps the unit compact for in-duct or wall-mount controls applications
• Suitable for greenhouse, laboratory, food and beverage, IAQ, parking garage, and agricultural environments

Compatibility

Designed for use with building automation systems and DDC controllers that accept 0 to 5V analog input signals in continuously occupied commercial, industrial, and agricultural applications.

Installation Notes

Installation should be performed by a licensed HVAC controls technician or building automation specialist familiar with low-voltage analog wiring practices. Power down the BAS controller or associated panel before making wiring connections. Follow local codes and the manufacturer wiring diagram for proper signal and power terminations. Verify that the receiving controller input is configured for a 0 to 5V analog signal before commissioning.
