The Model 2422 is a compact, low-noise, three-axis MEMS DC accelerometer designed for test and measurement applications limited to providing +5V DC excitation. It features excellent long-term stability, thermal resilience, and a rugged anodized aluminum housing with an integrated 3-foot shielded cable. Each unit includes three hermetically sealed SDI sensors, individually calibrated and serialized. With outputs of ±4V differential or 0.5–4.5V single-ended, it performs reliably from -55°C to +125°C.
