Silicon Designs Inc.: Vibration Monitor

Company: Silicon Designs Inc.

Description: The nitrogen-damped and hermetically sealed SDI Model 1525 Series is expressly designed for tactical navigation, seismic, and other zero-to-medium-frequency instrumentation applications that require high repeatability, low noise, and maximum stability. Each miniature hermetically sealed package combines a microelectromechanical system (MEMS) variable capacitive sense element and a custom integrated circuit that includes both a sense amplifier and ±4.0V differential output stage. Series units are also relatively insensitive to wide temperature changes and gradients. Each device is marked with a serial number on its top and bottom surfaces for traceability. A calibration test sheet is supplied with each unit, showing measured bias, scale factor, linearity, operating current, and frequency response.
