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
