Description
TST-2 indicator in thermoelectric temperature systems
TST-2 is an aircraft temperature indicator used in thermoelectric temperature measuring systems. The instrument is intended for remote measurement and visual indication of the average gas flow temperature in aircraft engines. It operates as the cockpit indicating unit of a temperature measuring chain and receives an electrical signal from thermocouples installed in the engine gas path. The instrument itself does not contact the gas flow directly and does not measure temperature without the associated thermocouple circuit.
Gas temperature indication through TST-2
The indicator displays temperature based on the thermoelectric signal generated by connected thermocouples. When the hot junctions of the thermocouples are heated by engine gas flow, a small electrical signal is produced and transmitted to the measuring instrument. TST-2 converts this signal into pointer indication on the scale. This allows the crew or maintenance personnel to monitor engine thermal condition during operation and identify temperature deviations that may require attention.
TST-2 with TST-282S equipment
TST-2 is used as the measuring indicator in the TST-282S thermoelectric thermometer set. In this system, the indicator works with T-82K thermocouples, a connection block, plug connector and related wiring. The thermocouple circuit and indicator must be treated as one measuring chain, because incorrect readings may result from damaged thermocouples, poor contact, wiring faults, connection block condition or indicator malfunction. The instrument is therefore normally checked together with the full temperature measuring set.
Aircraft application of TST-2
The indicator is used in aircraft engine temperature monitoring systems where exhaust gas or gas flow temperature must be measured remotely. It may be applied in systems for turboprop and turbojet engines, as well as in certain piston engine temperature measurement circuits. In helicopter applications, TST-2 is associated with the TST-282S set used for monitoring gas temperature in auxiliary or engine-related installations, depending on aircraft configuration and technical documentation.
Identification and ordering of TST-2
Before ordering TST-2, the instrument marking, scale range, thermocouple graduation and set configuration should be checked against the aircraft documentation or product passport. The indicator may be supplied separately or as part of the TST-282S temperature measuring set. For correct selection, provide the aircraft type, engine or installation type, temperature measuring system designation, existing indicator marking and a photo of the scale or data plate. The product is also known under alternative designations TST-2, TST2 and ТСТ-2.
