I have a odd ball unit.. called a "Informer" but its out of business.. but all the sensors are just standard stuff.. I happen to have a FEW of them left over from work.. thats pressure and temp sensors.. that unit gives me 18 channels(read outs).. I use most of them but 8 are EGTs... to be honest I wouldnt buy anything that needed special sensors... you can buy the standard 0-5v and K stuff on line pretty cheap
