TE Connectivity 820M1 series embedded piezoelectric accelerometer

The Model 820M1 is a low cost, board mountable accelerometer designed for embedded condition monitoring and preventive maintenance applications. The piezo-electric accelerometer is available in ranges from ±25g to ±500g and features a flat frequency response up to >10kHz. The model 820M1 accelerometer feature a stable piezo-ceramic crystal in shear mode with low power electronics, sealed in a fully hermetic LCC package.

The PE technology incorporated in the 820M1 accelerometer has a proven track record for offering the reliable and long-term stable output required for condition monitoring applications. The accelerometer is designed and qualified for machine health monitoring and has superior Resolution, Dynamic Range and Bandwidth to MEMS devices.
