Sensor having thermal gradients

A method, comprising:

• providing a one-piece housing;
• defining, in the one piece housing, a first recess configured for depositing and at least partially embedding a corresponding first transducer assembly within in the housing;
• defining, in the one piece housing, a second recess configured for depositing and at least partially embedding a corresponding second transducer assembly within in the housing;
• configuring a first port to extend from the first recess and through an end portion of the one-piece housing such that the first port is defined in the one-piece housing and configured for communication with a first pressure;
• and
• configuring a second port to extend from the second recess and through a plurality of channels in communication with a plurality of respective openings distributed around a side portion of the one-piece housing such that the second port is defined in the housing and configured for communication with a reference pressure.
