1. A pressure transducer system comprising pressure exposure means for being exposed to the fluid whose pressure is to be sensed, reference pressure means for obtaining a reference pressure, sensing means operatively connected to said pressure exposure means for sensing the pressure of the fluid exposed to the pressure exposure means and means operatively connected to said pressure exposure means and to said pressure sensing means for reducing pressure sensing errors caused by temperature variation comprising means for maintaining at least a portion of said pressure exposure means and at least a portion of said pressure sensing means at a substantially constant elevated temperature above the temperature of the environment surrounding at least a portion of said pressure transducer system comprising heating means, temperature sensing means for sensing the temperature of at least a portion of said pressure exposure means and at least a portion of said pressure sensing means and preheating means located adjacent to said temperature sensing means for preheating said temperature sensing means in advance of heat received from said heating means.
