Measure motor temperatures and main pack voltage in realtime
with the Graupner Temperature and Voltage Sensor. Connect directly to surface receivers (i.e.
GR-4, GR-8) and surface radios (i.e. X-8N, X-8E) to provide visual and audible
warnings when temperature/voltage thresholds have been reached.
- Simple and economical solution to measure temperatures and
- Multi-Level Telemetry Warnings
- Graupner Temperature and Voltage Sensor
I have several of these mounted to my R/C cars. They work really well on my electric vehicles, how ever mounting them is a bit of a challenge. I use Traxxas P/N 6535 to mount them to my 540 sized brushless motors. If you use Traxxas P/N 6535 I recommend packing the groove full of some sort of thermal paste/grease and making sure there is a good layer of thermal paste/grease between the motor and the sensor. Dow Corning 340 thermal paste works great. I have been playing around with getting it to work on a nitro vehicle. Getting the temperature sensor and the top of the glow plug to read the same value is difficult. Also the glow plug and the head heat and cool differently. I have been playing with moving the sensor up and down to try and calibrate the system. Also, trying to mount the sensor so that you can get could thermal transfer to the sensor is also difficult on a nitro vehicle. A side from mounting issues, this thing works wonders for the price. It has saved a brushless motor of mine. It's nice to be able to set a alarm and stop the vehicle and change your gearing well before you over heat the motor. I still need to figure out some kinks with using it on my Mugen Seiki MBX7 Nitro with a SH PT003 engine.

The voltage and temperature sensor is great. I have ruined Lipo batteries because I did not know when the charge was below 3.4 volts. Save me money
