Ultralights Posted March 24, 2008 Share Posted March 24, 2008 I have just received the new replacement CHT and EGT senders for my 503 in the vampire, unfortunately the wire is not long enough to reach the panel and hence the gauges, does anyone know what type, resistance etc is required for a wire extension so it does not give a false readings? I am currently reading through the Aircraft Spruce and Wicks catalogs, and they have heaps of extension wires but of varying OHM resistances.. Thanks in advance.. Rob.

Yenn Posted March 24, 2008 Share Posted March 24, 2008 California Power Systems http://www.800-airwolf.com list extension leads in their catalogue. No details of wire type or resistance given. They are available in 5' and 10' lengths of 2 or 4 wires. Link to comment Share on other sites More sharing options...
Ultralights Posted March 24, 2008 Author Share Posted March 24, 2008 thanks for that, they have what i needed... :) Link to comment Share on other sites More sharing options...
sain Posted March 30, 2008 Share Posted March 30, 2008 Its normal to use thermocouple wire for the extensions - you can buy this in lengths or by the spool from various different places. Link to comment Share on other sites More sharing options...
Guest Teenie2 Posted April 1, 2008 Share Posted April 1, 2008 If its only a few feet use any wire. The resistance in a few feet is negligible.A few years ago I did testing,different dimensions and lengths = no change in indicated temp Link to comment Share on other sites More sharing options...
