ABSTRACT:
A pressure transducer system including a pressure transducer, a heater and a temperature sensor and controller for controlling the heater. A thermal lead network is also provided that has a resistor that is physically located in close proximity to the temperature sensor and thermally bonded so that the heat that this resistor generates reaches the temperature sensor well in advance of the heat that would ultimately reach the temperature sensor from the heater. In view of this arrangement, this pressure transducer system is capable of making precise measurements in a time-varying temperature environment.
