Max-80i: industrial galvanic O₂ sensor for OEM integration and acid gas environments
Engineers and buyers looking for a reliable industrial oxygen sensor for integration into an OEM gas analyser, process monitor or measuring instrument will find a robust solution of proven Maxtec quality in the Max-80i. The Max-80i is specifically designed for three fields of application where standard medical sensors fall short: environments with high CO₂ concentrations or other acid gases, applications that require a short response time, and custom OEM systems with a 3-pin Molex connection.
With an expected life of more than 1.200.000 %O₂ hours, the Max-80i has the longest life in the Maxtec sensor family, lowering the total cost of ownership for OEM manufacturers through less frequent replacement cycles and fewer maintenance stops.
Why the Max-80i for OEM applications?
Standard galvanic oxygen sensors are developed for medical or scuba applications in clean gas environments. In industrial environments with high CO₂ concentrations, acid gases or corrosive media, these sensors degrade faster and give unreliable measurement results. The Max-80i is specially developed to keep measuring stably in these demanding conditions.
The 3-pin Molex connection allows direct integration into OEM instruments without extra adapters or connection work. The short response time of less than 5 seconds at a 90% step change makes the sensor suitable for applications where fast detection of O₂ changes is critical, such as safety systems, gas alarms and process control.
Applications
The Max-80i is suitable for OEM manufacturers of gas analysers and process monitors in the chemical, petrochemical and food industries, safety systems for O₂ monitoring in confined spaces and gas conditioning installations, environments with elevated CO₂ concentrations such as fermentation, biogas and greenhouse gas monitoring, process monitoring where response time is critical, and laboratory instrumentation with custom electrical interfaces.
Difference from the Max-11 and Max-13
The Max-11 and Max-13 are medical sensors with gold-plated slip-ring or 3,5mm jack connection, designed for clean medical gas environments. The Max-80i is an industrial sensor with Molex connection, specially developed for environments with high CO₂ or acid gases and for OEM instrumentation where a standard medical connection is not suitable. The Max-80i also has the shortest response time of the three models (less than 5 seconds vs. 12 seconds for the medical versions) and the longest expected life (>1.200.000 %O₂ hours).
