For sensors and many other products, smaller size, higher performance and/or longer life are all very desirable attributes. The Zirconia Miniature series oxygen sensors from SST Sensing Ltd achieves all of these. Offered in 12-mm diameter metal cans, the 5-pin sensor has a response time of as little as 4 seconds and covers an oxygen range from 0.1% to 100%. In addition to operating in oxygen pressures from 2 mbar to 3 bar with high accuracy and linearity, the sensors can cope with temperatures up to 400°C. This and other design characteristics allow the sensors to function and provide reliable data across an extensive operational lifespan, even in the most challenging of environments.
