Abstract: A polymeric fluid sensor includes an inlet configured to receive fluid and an outlet. A polymeric tube is fluidically interposed between the inlet and the outlet and has a first sensing location with a first sidewall thickness and a second sensing location, spaced from the first sensing location, with a second sidewall thickness. A sleeve is disposed about the polymeric tube. The first sidewall thickness is less than the second sidewall thickness and a first sensing element is disposed at the first location and a second sensing element is disposed at the second location. In another example, the first and second sidewall thicknesses are the same and a fluid restriction is disposed within the polymeric tube between the first and second sensing locations.

Abstract: A system for non-intrusively measuring process fluid pressure within a process fluid conduit is provided. The system includes a measurement bracket configured to couple to an external surface of the process fluid conduit. The measurement bracket generates a variable gap based on deformation of the process fluid conduit in response to process fluid pressure therein. A gap measurement system is coupled to the measurement bracket and provides an electrical signal based on a measurement of the variable gap. A controller is coupled to the gap measurement system and is configured to calculate and provide a process fluid pressure output based on the electrical signal and information relative to the process fluid conduit.

Abstract: A sensor includes a diaphragm having a bonding portion and a main boss separated from the bonding portion by at least one channel, the main boss having a first side face, a second side face and a chamfered corner face connecting the first side face to the second side face. A base of the sensor has a first contact area aligned with the main boss and separated from the main boss, wherein the bonding portion of the diaphragm is bonded to the base. At least one sensing element senses movement of the diaphragm.
