摘要

Phase I of the program, which consisted of the development of a sensor capable of detecting temperature changes as a function of viscosity changes, has been completed. This type of sensor, consisting of an orifice bridge circuit, has resulted in a device with a threshold above internally generated noise of 0.8C (1.5F). Data was obtained using a "noise free" Freon source provided by an air pressurized bladder.nTests conducted to operate the sensor from a typical Freon centrifugal pump system employing an air bubble accumulator for noise attenuation disclosed the sensor could be used only to sense temperature changes greater than 3.3C (6F) because of the excessively noisy output. This is attributed to the high frequency-pressure fluctuations in the Freon supply to the sensor.
