Abstract
A pressure transmitter for sensing a pressure of a process fluid in an industrial process includes a pressure sensor body fluidically coupled to the process fluid configured to receive an applied pressure related to a pressure of the process fluid. The pressure sensor body has a high pressure region configured to deform in response to the applied pressure and a low pressure region configured to deform in response to the applied pressure. A high range resistor bridge circuit is mounted in the high pressure region having a powered node, a common node and an output node and has a resistance which changes in response to pressure applied to the high pressure region. A low range resistor bridge circuit is mounted in the low pressure region and has a powered node, a common node and an output node and having a resistance which changes in response to pressure applied to the low pressure region. A pressure output circuit couples to the output node of the high range resistor bridge and the output node of the low range resistor bridge and provides an output related to the applied pressure based upon a voltage difference between the output node of the high range resistor bridge and the output node of the low range resistor bridge.
