INDUSTRIAL-GRADE MEMS DC
SURFACE MOUNT ACCELEROMETERS

Industrial-grade surface mount accelerometers must be rugged, sensitive, accurate, reliable, and cost-effective.  Silicon Designs builds all of its industrial MEMS DC accelerometers with these key elements in mind to support wide variety of demanding applications.  Models 1521, 1522, and 1531 are ideal for most zero-to-medium frequency industrial and OEM applications.

IDEAL FOR TEMPERATURE-SENSITIVE INDUSTRIAL APPLICATIONS

The 1522 is the upgraded sister of the Model 1521, also for use between -55°C and +125°C. They’ve been individually temperature tested to have improved performance under more temperature-intensive applications with only half of the bias and scale factor over temperature than the 1521. The 1522 is ideal for applications that swing rapidly through the temperature range or persist at the hot or cold ends for long periods of time.

PROVEN APPLICATIONS:

· elevator monitoring

· platform leveling

· flight test systems

· hostile environment R&D

· calibrating other accelerometers

HIGH-TEMPERATURE INDUSTRIAL APPLICAITIONS

The 1531 has the same performance specifications of a 1521 but is specially designed and carefully manufactured to keep working at temperatures up to +175°C. It’s built with high-temp materials and tested to make sure it stays dependable at extra high temperatures.

PROVEN APPLICATIONS:

· drillstring vibration monitoring

· wellbore surveying

· directional navigation

· formation measurement

· downhole equipment shock information
