Honeywell Duct CO2 Sensor - C7232B1030/U

The Honeywell Duct CO2 Sensor is a high-grade industrial product, specifically designed for ventilation control based on CO2 levels. It utilizes Non-Dispersive Infrared (NDIR) technology to accurately measure the concentration of carbon dioxide gas. This versatile sensor can be supplied with a Liquid Crystal Display (LCD) showing sensor readings and status information for superior visibility and control.

One of the defining features of this sensor is its compatibility with output voltages or currents based on detected CO2 levels. Configurations are available with a Single Pole Single Throw (SPST) relay output. An inbuilt feature, the Automatic Background Calibration (ABC) algorithm, based on extensive term evaluation, substantially minimizes the maintenance usually required for typical zero-drift checks.

The sensor is enclosed within a sturdy, durable plastic casing, which adheres to the National Electrical Manufacturers Association (NEMA) 3 standards. Equipped with an 8-10 probe lead, this device is predominantly intended for duct mounting. The output voltage signal range that this Sensor supports is 2 to 10 V or 4 to 20 mA, thereby enhancing its operational flexibility. The field-selection feature allows for the detection of CO2 gas, positioning this product as an indispensable tool for specialty gas applications. This sensor requires a stable supply voltage of 24 VAC/DC.
