914World.com _ 914World Garage _ CYL head temp sensor

Broke my good Fluke meter, had to use my backup meter. Still a good meter, with data logging to a pc even, but do these values look correct ?

47 deg measured with a K thermocouple = 3.6K ohm
85 deg 1.9 K ohm
213 deg .218K ohm

Close enough for gov't work. Or for our fuel injection.

According to http://members.rennlist.com/pbanders/DJetParts.htm the sensor should read:

> 2K ohms at 68 deg. F for all but 1973 2.0 L, > 1.2 K ohms for 1973 2.0L

Hotter temps will read lower, colder temps higher. By ~350F or so, the resistance should be about 100 ohms or less.
