Zusammenfassung:	A pressure transmitter with a transmitter housing having an outer wall providing thermal resistance. The outer wall extends from an isothermal island at a first end to a heat sink island at a second end. The isothermal island includes a fluid inlet, and pressure and temperature sensors. The heat sink island includes a primary heat load device that is heat sunk to an outer shell of an electrical connector. The connector contacts carry a current controlled by the transmitter, and a portion of the current is conducted by a primary heat load device. A circuit board controls the current to represent the pressure. A high accuracy, temperature compensated current output represents pressure.
