ITE-2TB is an aircraft tachometer indicator designed for continuous remote measurement of aircraft engine shaft rotational speed during flight and ground operation. The measured speed is displayed either as a percentage of the maximum value or in revolutions per minute, depending on the system configuration and installed speed sensors.

The ITE-2TB tachometer indicator operates in conjunction with engine speed sensors and is installed as part of the aircraft engine instrumentation system. The instrument provides real-time visual indication of engine operating parameters, allowing the flight crew to monitor engine режимs and ensure safe operation.

Structurally, the ITE-2TB is a dual-pointer analog instrument with two independent moving systems, enabling simultaneous indication of two shafts or two engines. The indicator is designed for operation across a wide temperature range and is suitable for use in various климатических and operational environments.

The instrument is equipped with an integrated dial illumination system, providing clear readability under low cockpit lighting conditions. The illumination is powered by low-voltage AC or DC supply.

ITE-2TB is produced in several modifications, including ITE-2TB2. While minor parameter variations may exist between versions, the core functional and metrological characteristics remain consistent.  The ITE-2TB tachometer indicator may also be referenced in technical documentation, spare parts lists, or user queries under alternative spellings and transliterations, including: ITE2TB, ITE 2TB, ITE-2TB, ITE2TB, ITE 2TB, ITЄ-2TB, ITЄ2TB, ITЄ 2TB.
