The TR-1-ITT (Inter Turbine Temperature) instrument is configured to interface with a Type-K thermocouple probe. The TR-1-ITT incorporates a map which is used to compensate for nonlinearities in the voltage vs temperature curves of the probe. This instrument has exceptional performance, reliability and features; a design driven by the 38+ years of experience. The TR-1-ITT Instrument was designed as a replacement for existing 2″ ITT instruments. Depending on your current installation you may need to wire in aircraft power and ground. The instrument features a 210° analog arc, backlight and a dimmable, digital display. The instrument’s faceplate will be custom built to match your aircraft’s limits (red/yellow markings). The TR-1-ITT fits into a 2″ standard round hole (MS28041-1A mount) and is 4.23″ long. It is FAA Certified to TSO: -C43c, -C44c, -C45b, -C47a, -49b, -C55a and comes with an FAA 8130-3 Airworthiness Approval Tag.

PER EI: "While the TR-1-ITT would work well as a replacement for the M-1-ITT, it is not quite a plug and play installation. Some rewiring would need to be performed, and an adapter plate (A-104) would be required to fit the TR-1-ITT in the M-1-ITT's 2-1/4" hole."
