Model LPA100T Low-Power Low-Voltage Accelerometer

Brand: Wilcoxon Sensing Technologies
Request Information
The heart of the LPA100T accelerometer incorporates new technology and innovative designs. Breaking from conventional sensor power, the LPA100T operates from low voltage (3-5 volts) and consumes less than 300 µWatts. Traditional sensors typically operate at 48 mWatts; the LPA100T offers 100x energy savings. In addition to low-power consumption, new patented circuitry minimizes settling time to less than ten milliseconds while still preserving 0.3 Hz low end frequency (traditional IEPE sensors require up to ten seconds). 

The key advantage of a fast settling time when using multiplexed applications (online monitoring systems) is that the entire sensor field can be scanned faster. Since each data point is refreshed more frequently, machinery health can be monitored in real-time. This results in improved asset protection and reliability. The LPA100T is an ideal solution for wireless, battery-operated or energy harvesting applications due to its low power consumption. A built-in electronic temperature sensor provides additional machinery health data from the mounting location. 

The LPA100T is also available certified for use in hazardous areas (Class I, Div 2/Zone 2).
Features
  • Ultra low power consumption (300 μW)
  • Operates down to 3 V
  • Fast BOV settling time of <10ms
  • Comes with the industry popular M12 connector
  • Hermetically sealed
  • ESD-protected
  • Reverse wiring protection
  • Manufactured in an approved ISO 9001 facility
  • U.S. Pat. No. 9,269,886 B1
