Electrochemical Sensor Installed in 10 Million Homes Worldwide

Jun 11 2010

At the heart of more than 10 million residential carbon monoxide detectors installed in homes throughout the world is City Technology’s ECOSURE electrochemical sensor, giving the occupants peace of mind and security from the lethal threat posed by the silent escape of invisible carbon monoxide gas from faulty or badly adjusted heating devices. ECOSURE is the sensor of choice for the great majority of CO detector manufacturers because of its performance, stability, reliability and extended operational life. It is also increasingly used in multi-sensor fire detectors to improve their detection reliability and reduce their false alarm rates.

ECOSURE is a two-wire electrochemical sensor with inbuilt filtering that protects it from poisons, interfering gases and dust, minimising the possibility of false alarms. Its inherent stability means that instrument manufacturers do not have to provide complex compensation circuitry. The sensors are manufactured in a highly automated manufacturing facility and comprehensively tested at each intermediate stage during the production process. As a result, the standard deviation in the output of individual sensors is extremely small, again enabling instrument manufacturers to simplify their instrument designs, thereby reducing time to market and improving manufacturability.

In addition to its stability and false alarm immunity, the sensor is extremely fast to respond to the presence of carbon monoxide, reaching T90 in less than 20 seconds. It is mechanically robust, can be installed in any orientation without affecting performance and it operates from -10 to +50°C with continuous relative humidity ranging from 15 to 90%.
