With reliable, extended-life XCell Sensors, there’s no need to replace sensors after two years. • Typical life greater than four years • Laser-welded sensor housings eliminate opportunities for leaks • Proprietary operating mode of the combustible sensor helps it stand up to poisons over the life of the sensor • End-of-sensor-life warning gives advanced notice to user, reducing service outages
Building on years of sensor design experience, MSA is revolutionizing sensor technology with breakthroughs in design that improve performance. • Sensor response and clear times under 15 seconds • Bump test under 15 seconds • Span calibration time of 60 seconds • Greater signal stability and repeatability under changing or extreme environmental conditions • Two-tox CO/H2S sensor with virtually no cross-channel interference • The digital output of the sensors makes them much less susceptible to RF interference
