Product Description

Gem System EGT Probe 2870 is a clamp-style exhaust gas temperature sensor that mounts on an exhaust stack to monitor engine exhaust temperature. It is used with compatible engine monitoring systems to provide EGT indications for aircraft engines.

0 1. Overview

This exhaust gas temperature probe uses a thermocouple element housed in a special alloy sheath that withstands exhaust environments. The sensing element is attached to a stainless steel clamp that secures the probe to the exhaust stack. Installation places the probe tip through a small hole in the exhaust pipe, where it is retained by the adjustable clamp around the stack. The probe is a grounded design, with resistance between the two leads specified as less than 2 ohms when tested with an ohm meter. The clamp accommodates exhaust pipes from 1-5/16 inch to 2-1/4 inch in diameter, and the probe diameter within the clamp area is 1/8 inch. All probes supplied under this part share the same lead length for wiring consistency in the installation.
