• WiNG-AIR3 (1)


Monitor Air Velocity Wirelessly

Poor or obstructed airflow can significantly affect cooling performance.  In addition, it will lead to equipment failure.  Wirelessly monitor air velocity with sensors that monitor air handling equipment and quickly detect impeded airflow, stalled fans, leaks, blockages or clogged filters.

The WiNG-AIR3 is the most economical of RLE’s three WiNG air velocity sensors. It has a range of 0-3 meters per second, +/-10%.

Small Footprint, Big Battery Life

WiNG sensors are compact and unobtrusive, yet provide an industry leading battery life.  WiNG-AIR3 sensor batteries will last up to 11 years at room temperatures.

WiNG sensors maintain this extended battery life while communicating readings to the WiNG-MGR web interface every 10-20 seconds. We knew it was important to our customers that we didn’t sacrifice data responsiveness in order to extend battery life.

Unprecedented Transmission Range

The WiNG system has an unprecedented transmission range between sensors and manager; up to 100 feet through multiple walls, up to 270 feet through one wall, and up to 600 feet indoor, direct line of sight.

For applications that require signals to be pushed through more complex or noisy RF environments, the WiNG-RXT range extender can be implemented.  They add up to 1,000 feet direct line of sight transmission distance to the application.

Designed With Your Facility’s Security In Mind

WiNG sensors communicate directly – and only – with a WiNG-MGR or WiNG-RXT utilizing small, proprietary packets in the 900MHz or 868MHz frequency range.

WiNG sensors are not Wi-Fi based, do not have IP addresses, and do not utilize IP communications.  This means they cannot connect to your company’s Wi-Fi network and ensures that they cannot be used as unauthorized wireless access points.
