Description
T-102 thermocouple sensor for aircraft engines
The T-102 is an aircraft thermoelectric temperature sensor used for exhaust gas temperature measurement in turbine engine systems. In Mi-8 parts catalogs it is listed as a thermoelectric temperature sensor without wire. The sensor is used in temperature measurement chains where the signal is generated directly by the thermocouple junction and then transmitted to onboard measuring equipment. In practical helicopter maintenance, T-102 is usually discussed together with the 2IA-6 exhaust gas temperature system.
Temperature signal from the T-102 thermocouple
The T-102 produces a low-level thermoelectromotive force that changes with gas temperature. This signal is not a normal voltage supply signal and should not be treated like an ordinary electrical line. It has to pass through thermocouple wiring and compensating connections before it reaches the amplifier and cockpit indicator. Because the signal level is small, poor contacts, mixed wiring materials or damaged insulation can create a temperature error that looks like a sensor fault.
T-102 in the 2IA-6 measuring system
In the 2IA-6 system, T-102 thermocouples are used as the primary sensors for measuring engine exhaust gas temperature. The set is arranged as two independent measurement channels, one for each engine. Technical descriptions of 2IA-6 mention a complete set of 28 T-102 thermocouples, with 14 sensors per engine. The sensors are connected in parallel to produce an averaged temperature signal from the engine gas path. This signal then goes through PK-6 transition blocks to the 2UE-6B Series 2 amplifier and the 2UT-6K cockpit indicator.
Aircraft and engine use of T-102
The T-102 is associated with TV3-117 and TV3-117VMA engine applications, including Mi-8 family helicopters and related installations. Catalog references also show use with AL-21, AI-9-3B and AI-24UB equipment, so the sensor should always be matched by the actual engine and measuring system documentation. On Mi-8 / Mi-17 helicopters, T-102 works in the exhaust gas temperature chain used by the crew for monitoring engine condition during start, warm-up, takeoff and flight operation.
Identification and ordering of T-102
Before ordering T-102 thermocouples, the aircraft parts catalog and the 2IA-6 system documentation should be checked. It is important to confirm whether the request is for a single thermocouple, a full set for one engine, or a complete set for both engines. For correct selection, provide the helicopter type, engine type, installed temperature measuring system and the required quantity. The product is also known under alternative designations T-102 and Т-102.
