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