Carbon Monoxide (CO) Gas Sensor RS-CO-I20-2-2000P-2 4-20mA
The RS-CO-I20-2-2000P-2 is a fixed carbon monoxide gas sensor engineered for continuous ambient CO monitoring in industrial, commercial, or building automation systems. It is housed in a durable, sealed enclosure to defend the internal sensing element from dust, moisture, and mechanical stress. It is intended for semi-permanent installation in locations where CO accumulation is a safety concern, such as boiler rooms, garages, tunnels, or near combustion equipment.
Carbon monoxide gas enters the sensor chamber via diffusion through a membrane or vent port and reaches the internal electrochemical sensing element. The CO molecules react at the electrode surface to induce a proportional electrical signal change. Onboard signal conditioning circuitry then linearizes and scales that signal to a 4-20 mA analog current output. Compensation circuits correct for ambient temperature and humidity influences to enhance measurement consistency.
Over extended operation, the RS-CO-I20-2-2000P-2 is designed to maintain stability via low drift electronics and calibration correction mechanisms. Its 4-20 mA output is directly compatible with PLCs, data acquisition systems, or alarm controllers. When CO levels exceed defined thresholds, the sensor’s signal can trigger ventilation systems, alerts, or safety interlocks. Its construction supports reliable, continuous performance with minimal maintenance in demanding environments.
