摘要: A temperature sensor includes a probe (15) accommodating a charge gas the pressure of which is a function of the temperature thereof, and a number of bellows (65, 75 and 85) or similar pressure responsive devices disposed in a chamber (12) which is thermally isolated from the charge gas. The chamber includes a jacket (150) through which a fluid such as gas turbine engine fuel flows to insulate the pressure responsive devices from ambient temperatures.

摘要: A pressure or temperature sensor that translates a pressure or temperature signal into a hydraulic pressure signal. The sensor or transducer utilizes no bearings, levers or pivots that would introduce errors and the control plate is supported within the casing only by bellows. The transducer has use in transmitting a hydraulic pressure signal to the fuel control in a gas turbine in response either to a pressure or temperature signal such as engine inlet temperature or compressor discharge pressure.
