Abstract: A pressure transmitter with first and second absolute pressure sensors receives process pressures from corresponding first and second process inlets. A transmitter circuit coupled to the first and second absolute pressure sensors generates a differential pressure type output. A third absolute pressure sensor coupled to the transmitter circuit receives atmospheric pressure from a third inlet. The transmitter circuit generates a second type of transmitter output that can be a gage or absolute pressure type. Single crystal. sapphire pressure sensors are preferred to provide enough accuracy for measuring accurately over 200:1 pressure range.

Abstract: A process transmitter (102) has a housing (110) that contains transmitter circuitry (206). The transmitter circuitry (206) is configured to provide a display output and is also configured to couple to a process control loop (106). A LCD display (130) is embedded within a transparent or translucent polymeric layer (132) in the housing (110). The LCD display (130) is coupled to the display output and is configured to display information through the polymeric layer (132).

Abstract: A capacitive pressure sensor is formed with sensor body and diaphragm components made of near net shapeable sintered ceramic. In one configuration, the differential pressure sensor has two sintered ceramic cell halves with an internal sintered ceramic diaphragm captured between the two cell halves. In another configuration, two side-by-side sintered ceramic cell halves have individual sintered ceramic diaphragms, and the chambers of the two cell halves are connected by metal tubing.
