QGateway
The QGateway receives and transmits data wirelessly from the DGA-LT1
sensors to a central monitoring platform. The QGateway is battery powered
with solar battery charging. The QGateway receives and transmits encrypted
raw signals via RF frequency to and from the DGA-LT1 sensors. That data is
then transmitted via cellular transmission through TCP/IP to the remote
monitoring system. This data is viewed via Qualitrol’s QualConnex
®
web portal.
QualConnex
®
Web Application
Data from the DGA-LT1 can be viewed in the QualConnex web application. QualConnex
provides the user with the ability to track oil hydrogen concentration (ppm), oil moisture
concentration (%RH), and oil temperature (°C) levels over time and compare against
user-defined alarm settings. The web interface displays QGateway reports including
battery level and signal strength.
The QualConnex web interface allows the user to configure the monitor’s alarms and
settings and provides a monthly report of all monitored assets.
