Analogue accelerometers for the industrial market measure to 40g
Maximum supported bandwidths range from 4.5 kHz to 8 kHz. Both sensors have built-in self-test functions, consume 0.25 mA at 3.3V and are delivered in 10-pin 3 x 3 mm LGA packages.
Kionix comments; “Unlike the consumer market, with its short upgrade cycles, it often doesn’t make sense in the industrial sector to cast aside existing infrastructure and directly upgrade to digital solutions due to the significant capital already invested, the long lifetimes of equipment, and the need to ensure continuity. So although digital rules in the consumer world, analogue is still very alive and often preferred in industrial applications. Recognizing this need, Kionix is complementing its high bandwidth, medium-g digital offerings with the addition of the KX220 series of analogue accelerometers.”
Since the typical applications of industrial sensors are monitoring machines and physical processes, the g-range and bandwidth requirements are typically higher than those in hand held consumer devices. These sensors are targeted to assist in applications ranging from vibration monitoring to shock and impact detection and measurement. Markets served are machine health and diagnostic monitoring, robotics and automation, and manufacturing process control.
