As the first step in mu Dynojet Dyno conversion I've removed the OEM electronics: EX+ stack, Theta (retarder) controller and breakout board.
Connected to the latter there was (now removed) a Raytek infrared sensor to monitor the temperature of the retarder and display it in the control software.
First of all I'd like to know if this is a real world useful feature.
In my setup I'm planning to occupy 2 analog input of the DAQ for lambdas (I use to tune V2 Ducatis). I've found that this particular sensor has a 0-5V output, so it could be recycled as an input to the software.
The sensor has 5 wires:
2 for power supply
2 for ground and 5V
1 for shield
Should the shield be connected somewhere?
Do you have a link to the spec of the sensor?
In general, you don't need to measure the temperature of the brake. They get warm, but it is nothing to worry about, except they get weaker when warm. I have seen them glowing hot and they still survived.
But an infrared temp sensor is a cool feature, so nice if you get it working 🙂
The sensor on the Dynojet 250i is a Raytek RAYCI3B10L
