CHT 18mm Ring Senders

[Roger_Peterson]

I have to use 18mm ring sensors on my 0--200. I ordered Falcon CP-018 CHT Senders, but the color code on the wires is white and black. I cannot find out what type of thermocouple wire they use so suspect they won't work. What ring sender do you recommend.

We don't have a specific recommendation. They need to be type J thermoucouples, and 18mm ones are available from most of the big avionics/aviation supply houses. One example from a reputable manufacturer that looks to be the right type is http://www.aircraftspruce.com/catalog/inpages/umachtprobes.php .

Note that the ones you have may well be type J, depite the wire colors. See http://www.omega.com/techref/thermcolorcodes.html for details.
