Lead-free, RoHS-compliant and high life expectancy
2017-04-03 07:11:52, Angst+Pfister Sensors and Power AG The PO2ES-103P electrochemical sensor is a robust oxygen sensor for industrial and medical applications. It is lead-free and RoHS-compliant, which is an advantage for new product developments on the one hand, but also an argument for replacing lead-based sensors in old product lines on the other.
In typical medical applications in out-of-hospital care, such as respiratory or CPAP (continuous positive airway pressure) therapies, the lifetime of conventional electrochemical sensors is affected by high oxygen exposure, high gas flow and the presence of CO2 - limitations that do not affect the PO2ES-103P lead-free sensor. It is characterized by an expected operating life of 1 200 000 vol% O2 hours and its lack of cross-sensitivity to CO2.
The most common industrial requirements for oxygen sensors concern low drift of the output value, signal stability and insensitivity to acid gases such as CO2, CO, NO and H2S. With these requirements in mind, the PO2ES-103P was designed to provide a stable zero output value of less than 2000 ppm, excellent signal stability over its lifetime, and resistance to acidic gases. In addition, the sensor has a fast response time of < 10 seconds (T90) and can be used at temperatures close to 50°C for short periods.
