ITE-2TB2 is an aircraft tachometer indicator designed for continuous remote measurement and indication of aircraft engine shaft rotational speed during flight and ground operation. The measured rotational speed is displayed on a percentage scale relative to the maximum value and is used for real-time monitoring of engine operating modes.

The indicator operates in conjunction with engine speed sensors and is installed as part of the aircraft engine instrumentation and monitoring system. It provides reliable visual indication of engine speed parameters required for safe operation of aircraft powerplants.

ITE-2TB2 is a dual-pointer analog instrument with two independent moving systems, allowing simultaneous indication of two shafts or two engines. The instrument is designed for operation under severe environmental conditions and maintains metrological characteristics within the specified operating temperature range.

The indicator is equipped with lamp-type dial illumination to ensure readability under low cockpit lighting conditions. Illumination is powered by a low-voltage supply and meets the power consumption limits specified in the technical documentation.

According to the manufacturer’s passport, ITE-2TB2 is interchangeable with the ITE-2TB1 tachometer indicator and complies with the applicable technical specifications when storage, transportation, installation, and operation conditions are observed.

Alternate Designations:
ITE-2TB2 may also be referenced in technical documentation, spare parts catalogs, and search queries under alternative spellings and transliterations, including: ITE2TB2, ITE 2TB2, ITE-2TB2, ITE2TB2, ITE 2TB2, ITЄ-2TB2, ITЄ2TB2, ITЄ 2TB2.
All listed designations refer to the same instrument type.
