Analogue accelerometers sense vibration for industrial and commercial markets

A compact, high-bandwidth design for the KX220 sensor family supports up to ±40g. This makes them suitable for vibration sensing and shock detection in industrial and commercial applications, says Kionix, a Rohm company.

The KX220 sensor series is a family of medium-g, tri-axis analogue accelerometers. Initially there are two versions are available, the KX220-1071 and the KX220-1072, providing ±20g and ±40g ranges respectively. Maximum supported bandwidths range from 4.5 to 8kHz. Both sensors have built-in self-test functions, consume only 0.25mA at 3.3V and are delivered in 10-pin 3.0 x 3.0mm LGA packages.

Analogue technology is often preferred in industrial applications, Kionix finds. Recognising this need, the company says it is complementing its high bandwidth, medium-g digital offerings with the addition of the KX220 series of analogue accelerometers.

Typical applications of industrial sensors are monitoring machines and physical processes. Therefore, points out Kionix, the g-range and bandwidth requirements are typically higher than those in handheld consumer devices. The sensors are targeted to assist in applications ranging from vibration monitoring to shock and impact detection and measurement. They can be used in markets as diverse as machine health and diagnostic monitoring, robotics and automation, and manufacturing process control.

The industrial sensors are sampling now.
