Electrochemical CO Transducer LFWS10

An electrochemical CO sensor includes two electrodes (the working electrode, and the counter electrodes) surrounded by a liquid electrolyte conductor. The main working electrode is typically constructed of platinum which provides a catalyst for the CO gas. This working electrode is supported by a gas-permeable, yet waterproof membrane which enables CO to enter and electrochemically oxidize with the platinum working electrode. Once this oxidation takes place, the electrons from this electrochemical reaction flow through the external circuit of the device, and electrons are transported by electrolyte, allowing the onboard sensor to signal the presence of CO. 

The electrochemical CO sensor – due to their more economical points – is now one of the hottest choices for facility and health protection

Description of Electrochemical CO Transducer LFWS10

  • An electrochemical detector can offer incredible accuracy.

  • There are a few key advantages of selecting an electrochemical detector over the other main types of sensors:

  • Accuracy: Thanks to the selective filter, other gases are removed before they reach the working sensor. This ensures that the device is highly accurate when it comes to detecting carbon monoxide, resulting in fewer false reactions.

  • Flexible applications: Unlike others, including semiconductor sensors, electrochemical sensors can operate at regular room temperature, and only requires minimal power. In this way, it can be utilised in nearly any industrial environment, including those where false positive CO alarms may have been an issue in the past.


Application of Electrochemical CO Transmitter

An array of factors can impact the quality of indoor air, and it's imperative to monitor for contaminants, particles and gas. Carbon monoxide, for example, is known as a silent killer, with exposure sending many people to the emergency room every year.

It is a combination of a mature electrochemical detection principle and sophisticated circuit design. In facility management, there are numerous important elements that supervisors need to keep track of in order to maintain operations and ensure a safe and healthy environment for workers. Particularly in industrial settings, not the least of these considerations is air quality.
