SE120 piezoresistive accelerometer

2 mA/g, 0 to 75 °C, 0.2 to 350 Hz.

The SE120 piezoresistive accelerometer is a high-quality, high-reliability vibration sensor with a piezoresistive sensing element and integrated electronics that provides a current output.

The SE120 is designed and built for use in harsh environments.

Features
  • Designed for the long-term measurement of vibration in harsh environments, such as hydro turbines and fans (lower-speed machines)
  • Low frequency response: 0.2 to 350 Hz
  • Current output (2 mA/g) for signal transmission over long distances: up to 1000 m
