Modified Gas Capsule Temperature Sensor TDK-M for Accurate Fuel Pressure Control

Thermodat gas capsule modified is designed to output the fuel command pressure drop depending on the temperature of the thermocouple placed in the measured medium to the units of the automatic control system of gas turbine engines.

The working body of the thermoreceiver is helium gas ampouled in the helix cavity of the thermoreceiver and in the supramembrane cavity. Physicochemical properties of helium make it possible to ensure and control a high level of tightness of the thermal receiver cavities with a high degree of reliability, using modern testing equipment..
