Costas -- sorry I never noticed the update to this topic got a new posting.

My IR temp sensors are connected to a Motec M816 expansion box. This communicates over the CANbus to the main ADL logger. The IR temp sensors are 0-5 volt sensors that are powered by 5 volt. We can adapt them to practically any system that can support a 5V input. The sensors are relatively low cost (the retail price is about $150 each), but we can work on a discount for 12 of them
