ITE-2T

ITE-2T tachometer indicator for aircraft engines

ITE-2T is an aircraft tachometer indicator used for remote measurement and indication of engine shaft rotational speed. The instrument displays rotational speed as a percentage of the maximum value, allowing the crew to monitor engine operating conditions during flight and ground operation. It is part of the aircraft engine instrumentation system and is used where continuous visual indication of shaft speed is required. The unit is an indicator, not a speed sensor; it receives signals from remote engine speed sensors installed on the engine drive units.

Rotational speed indication through ITE-2T

The indicator provides analog pointer indication on a percentage scale. This format is common for aircraft engine tachometer systems, because the crew monitors engine speed relative to the approved operating range rather than only in absolute revolutions per minute. In a typical configuration, the instrument can work with two measuring systems, allowing simultaneous indication of two shafts or two engines. The operating range is the part of the scale used for normal monitoring, while the wider indication range supports reading outside the normal zone.

ITE-2T with D-2M engine speed sensors

The tachometer indicator operates together with D-2M engine speed sensors. These sensors are mounted on engine drive units and provide the input signal required for remote indication. In a dual-pointer tachometer system, two D-2M sensors may be used with one indicator to show two rotational speed channels. Correct operation depends on the sensor, wiring, connector condition and the indicator mechanism. If the reading is unstable or incorrect, the full tachometer chain should be checked rather than replacing the cockpit instrument alone.

Operating principle of the ITE-2T indicator

The working principle is based on the interaction between the magnetic field of a permanent magnet and the magnetic field of eddy currents generated in the sensitive element of the instrument. This electromechanical principle allows the pointer to move according to rotational speed input from the remote sensor. The system is designed for stable indication under aircraft operating conditions. Because it is a precision indicating instrument, attention should be paid to calibration status, pointer movement, scale condition and technical documentation during inspection.

Identification and ordering of ITE-2T

Before ordering ITE-2T, the marking should be checked against the aircraft parts catalog, engine instrumentation documentation or product passport. The instrument may also be referenced as ITE-2, especially when describing the complete tachometer system. It is used on various aircraft and helicopters, including Mi-26 heavy transport helicopters, depending on configuration. For correct selection, provide the aircraft type, engine type, installed tachometer system, existing indicator marking and a photo of the scale or data plate if available.
