| For reliability and durability reasons, E.I. will only manufacture ungrounded EGT probes. 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. Theres just not a good fix for a grounded probe. E.I.s ungrounded probes eliminate the problems associated with gound noise and ground loops, providing a stable display and 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. Screw-in type, Standard with most kits. Can be used in a pressure environment. 700°F max. E.I. products include all documentation and certifications |
