From our founding in 1992, Phase IV Engineering has been an innovator in wireless sensor design. We started as a type of “skunk works”, designing highly advanced and technically challenging sensors for Fortune 500 companies, NASA the US military, and scientific research. We invented the world’s first battery-free RFID wireless temperature and pressure sensor. (Among many other applications, this sensor currently flies inside the wheel valve stem of every Boeing 777 and 787 aircraft.) Phase IV has expertise in energy harvesting, RF design, low-power circuit design, and designing for very harsh environments. Our team’s over 100 years combined experience was a key reason our Phase IV Engineering team was recognized as the “Sensor Engineering Team of the Year” in 2015 by Sensors Magazine and won Product of the Year in 2017 from the RFID Journal. Now introducing the Leap Sensors® product line and software for industrial wireless sensor networks. The system, which has multiple patents-pending, is designed to meet your needs for a highly flexible and configurable system combined with short lead times and low configuration costs. We’ve also designed in “Gold Standard” data security. The Leap Sensors system makes it easy to integrate wireless sensor data into your company’s existing PLC or monitoring systems, so you can quickly achieve Industrial IoT (IIoT) monitoring, smarter processes, and rapid return on investment. With its modular, pre-configured design, our clients appreciate how the Leap Sensors system works “right out of the box”. Practical visionaries working to solve your sensor needs: With the Leap Sensor system, it’s more convenient than ever to execute your vision while respecting your budget and other constraints.
