An excellent engine analyzer starts with a well designed EGT probe!

 

New Quick Response EGT Probe:   Our new EGT probe is one-half the size (measured by area) of our standard probe. It’s also now the same size as JPI’s probe except for their tapered tip, which EI will not manufacture because of reliability and durability issues. The wall of a tapered tip probe can be as thin as .006 inches (approximately the thickness of a sheet of paper)! Obviously, no matter which exotic material JPI uses to produce their probes, a probe’s life expectancy is compromised by thin walls. E.I.’s new EGT probe was designed to provide fast response and long-life reliability. No compromises.

Ungrounded Probe Tip:  For reliability and durability reasons, EI will only manufacture ungrounded EGT probes. Why? Ground noise at the engine can be a big problem for any piece of electronic equipment. Grounded probes transmit this noise back to the instrument. Grounded probes can also produce ground loops between the engine ground and the instrument ground. All of these problems result in jumpy, unstable instrument readings. In order to try to eliminate these problems, some manufacturers use excessive filtering in their instruments, but this only results in a slow probe/instrument system response time. There’s just not a good fix for a grounded probe. E.I.’s ungrounded probes eliminate the problems associated with ground noise and ground loops, providing a stable display and a fast system response time. An engine analyzer MUST be coupled with a well-designed EGT probe to achieve excellence in the total analyzer/probe system.
