Jewell Instruments DMA Specifications
DMA Series - Digital MEMS Accelerometers
Making Sense out of Motion…
Jewell Instruments DMA Series
Accelerometers are an excellent
choice for cost to performance
trade off. The DMA is based on
silicon micro-machined MEMS
Capacitive Accelerometer
technology and designed for low
power and high stability.
