UniSens-E XT90 Serial – Powerful Universal RC Telemetry Sensor
The compact and powerful UniSens-E RC telemetry sensor measures and transmits voltage / current / power / capacity / energy / altitude / vario values.
Special version for connecting two batteries in series.The UniSens-E XT90 Serial comes with two XT90 sockets wired in series, allowing direct connection of two drive batteries—no separate adapter is required for serial connection.
The UniSens-E is a dedicated telemetry sensor designed specifically for all electric-powered RC models. It’s so small and lightweight, yet so powerful, that it can be used in almost any model.
In line with our philosophy of supporting as many systems as possible, the UniSens-E is compatible with Jeti Duplex, Multiplex M-Link, Graupner HoTT, Futaba, JR DMSS, FrSky, Spektrum (via Spektrum adapter), and PowerBox Core systems.
The telemetry protocol only needs to be selected once via the UniSens-E settings, using either our PC software "UniSens-E Tool" or the UniDisplay. The default setting is HoTT GAM.
To change settings or perform firmware updates via PC, a suitable USB interface such as our Item No. 2550, or an existing USB programming cable from Jeti, Multiplex, or Graupner is required. Refer to the manual for details.
Even without additional sensors, the UniSens-E can fully monitor your power system: voltage, current, and capacity.Thanks to the integrated high-resolution barometric sensor, it also provides altitude measurement and vario functionality.
You can configure extensive telemetry alarms that are reported through your transmitter.
The UniSens-E is available with various plug types—soldering is usually not required.The current measurement works bidirectionally, so plug polarity does not matter. Measurement direction is simply set in the configuration.
Using our UniDisplay, you can view all live data and configure all settings and alarms directly.
Whether in gliders, aerobatic planes, helicopters, HLGs, or slow flyers, the compact and lightweight UniSens-E fits almost any application—and it’s also perfect for RC boats, cars, and more.
With the UniSens-E, you’re getting a fully-featured universal RC telemetry sensor that leverages modern electronics to be your small but powerful helper in all your RC adventures.
