Product Description
Product Overview
The TE Connectivity 830M1 is a low-cost, triaxial piezoelectric accelerometer designed for embedded condition monitoring and preventive maintenance. It features a hermetically sealed LCC package, piezo-ceramic crystals in shear mode, and a flat frequency response up to 15kHz across all three axes. The 830M1 offers superior resolution, dynamic range, and bandwidth compared to MEMS devices, making it ideal for machine health monitoring and predictive maintenance installations. An integrated RTD temperature sensor provides simultaneous vibration and temperature data. Available in dynamic ranges from 25g to 2000g.
