For over four decades, gas-leak-detection sensor tech has remained relatively unchanged and proven costly and often unreliable. Advances have changed the landscape, though, with sensors now including multiple chemical sensors on a single silicon chip.
Pellistor/catalytic (CAT) bead sensors and non-dispersive infrared (NDIR) sensors have been the primary gas-detection methods for many decades. After NDIR was introduced in the 1960s, the gas-detection industry experienced a prolonged era with little innovation, until recently. Read More
