Abstract: A two-wire transmitter senses differential pressure, absolute pressure, and process temperature of a process fluid. The information can be used to provide an output representative of mass flow through a pipe. The transmitter has an electronics module housing attached to a sensor module housing.

Abstract: A two-wire transmitter senses a pressure using an internal pressure sensor. The transmitter includes an input for receiving a process variable from a remote sensor which is separated from the transmitter. Circuitry in the transmitters transmits information on a two-wire process control loop which is related to the sensed pressure and the process variable.

Abstract: A spring loaded seal is placed between three continuous groove walls between mating parts adjacent to a pressure transmitter isolator. The seal includes a resin ring with two ring walls conformable to two of the groove walls. A third ring wall has a continous slot extending into the ring. A coil spring is placed in the slot such that, upon mating of the parts, the third wall presses the coil spring toward the slot. This compresses the coil spring to sealingly force the first and second outer ring walls against the first and second groove walls respectively with a controlled force. The compression of the coil spring controls the sealing force to limit undersired distortion of the groove walls.
