Abstract: A process pressure transmitter system includes a process pressure transmitter housing and a process pressure sensor in the process pressure transmitter housing. A metal flange is configured to mount to a process vessel which carries a process fluid. An isolation diaphragm attaches to the metal flange and is exposed to the process fluid through an opening in the process vessel. The isolation diaphragm comprises a polymer diaphragm bonded to a metal face of the metal flange. A capillary passageway carries a fill fluid from the isolation diaphragm to thereby convey a process pressure to the pressure sensor.

Abstract: A pressure sensor includes an elongate body which deforms in response to an applied pressure having a cavity formed therein. An isolation diaphragm seals the cavity from a process fluid and is configured to deflect in response to applied process pressure from the process fluid. An isolation fill fluid in the cavity applies pressure to the elongate body in response to deflection of the isolation diaphragm thereby causing deflection of the elongate body. A deformation sensor is coupled to the elongate body and provides a sensor output in response to deformation of the elongate body which is indicative of the process pressure.

Abstract: A thermowell assembly for measuring a process temperature includes an elongate thermowell having a proximal end and a distal end. A bore extends between the two ends with the thermowell assembly configured to extend into a process fluid. An infrared sensor detects infrared radiation from the distal end through the bore of the thermowell and responsively provides a sensor output. A configuration is provided in which infrared radiation received by the infrared sensor from a wall of the bore is reduced and or radiation received from the distal end of the bore is increased.

Abstract: A multivariable fluid level detection system comprising a guided wave radar probe with sensor or sensors integral to the probe for producing sensor signal(s), a transmitter for transmitting guided microwave pulses down the probe, a receiver for receiving reflected microwave pulses, and a processor for producing a measurement of fluid level based upon a time difference between transmission of a pulse and receipt of a reflected pulse and the sensor signal(s).

Abstract: A process measurement system includes a sensor for producing a sensor signal as a function of a process parameter and a measurement circuit that converts the sensor signal to measurement data. A control circuit controls the amplitude of the sensor excitation to maximize signal strength over the entire operating ratio range of the sensor. This enhances resolution and noise rejection of the measurement circuit.

Abstract: A remote seal assembly for a process transmitter includes a seal body containing a cavity sealed by a diaphragm. The seal body configured to be mounted to a process element containing a process fluid such that a first side of the diaphragm is exposed to the process fluid. A capillary contains a fill fluid that is in fluid communication with the cavity and a second side of the diaphragm. A coupling has a capillary recess and two cavities separated by a second diaphragm. The capillary extends through the capillary recess and connects to the coupling such that the fill fluid in the capillary is in fluid communication with one of the two cavities and the second diaphragm. A thermally conductive element preferably extends continuously along the capillary from the seal body toward the coupling and into the capillary recess without contacting the coupling.
