MEMs technology applied to industrial sensing
1 min read
Analog Devices is expanding its iSensor intelligent sensor product family with the introduction of two inertial sensors that simplify the task of embedded shock and vibration sensing within industrial environments.
Bob Scannell, Analog Devices' business development manager for iSensor products, said: "The technology has been very successful in automotive and consumer applications, but less so in industrial because inertial MEMs devices have been at a low level of integration. However, customers are now looking for more application specific products, which means a much higher level of integration is needed."
The ADIS16240 is an integrated digital shock detection and capture system that combines iMEMS technology with embedded signal processing. The device has a low power triple axis shock and impact sensor and recorder, including an on chip programmable event capture buffer. Described by Scannell as fully autonomous, the ADI16240 is 10% of the cost of previously available devices, as well as 100 times smaller. Up to 256 samples can be captured anywhere around a peak event.
Meanwhile, the ADIS16220 is a digital vibration monitor that combines iMEMS sensing technology, embedded signal processing and a data capture system. According to the company, the combination of a digital interface and a 22kHz wide bandwidth high g accelerometer allows vibration monitoring capabilities to be embedded into industrial systems.
The ADIS16220 has three modes: set up; mid life duty cycle; and maintenance. "The part will help to detect an early shift in device performance," Scannell asserted.
