Wilcoxon also offers a 100 mV/g version of this embedded accelerometer, the LVEP100-TO5, with a similar wide frequency response and low noise characteristics. See the specifications.

The LVEP050-TO5 was packaged in a TO-5 standard transistor canister for easy integration into wireless sensors as well as industrial manufacturing equipment. It can be mounted inside motors, pumps, fans, and other rotating equipment, to enable machinery self-diagnostics and asset monitoring via the Industrial Internet of Things (IIoT).

Benefits of TO-5 packaging

Good vibration coupling from the canister base into the vibration pellet is essential to effective machinery health monitoring
Light weight preserves usable measurement bandwidth
Hermetic sealing prevents contaminants and moisture from entering the sensor, to ensure stable measurements over a long operational lifetime
Small size enables one- and three-axis accelerometer designs

Take more measurements using less battery

Ultra-low power consumption was a driving force behind the development of the LVEP050-T05, to provide an ideal solution for battery powered and energy harvesting applications like wireless vibration sensors.

Power consumption: 180 µW
Voltage source: 3.0 – 5.5 VDC
Current draw: 60 µA
BOV settling time: 350 µs

The importance of settling time

For applications that use power only when taking a measurement, the BOV settling time is critical to battery conservation.
