Abstract
A pressure-sensing device and method for making and using such device having a temperature differential between two portions of the device is disclosed. A solid-state heat pump, such as a thermo-electric cooler (TEC), is used to pump heat from a cold portion to a hot portion of the device. A pressure sensor sensing the pressure of a hot fluid is disposed in the hot portion of the device, and sensor electronics are disposed in the cold portion of the device.
