摘要： Floating the diaphragm portion of a diaphragm sensor in the pressurizing fluid frees the diaphragm from exterior housing forces, and makes overall manufacture and replacement inexpensive. A diaphragm can be protected from exterior stress by interspersing a channel between the diaphragm edge and the closure and support structure of an enclosing housing. By extending the channel and incorporating an adequate seal, the diaphragm structure may be made replaceable. The replaceable diaphragm further allows use of a smaller amount of costly materials, and makes repair less costly.

摘要： Process variable transmitters, and method for calibrating such device, are disclosed that support calibrating, within a single transmitter device, multiple operating ranges such that a transmitter can switch from a first calibration correction definition associated with a first calibrated range, to a second calibration correction definition associated with a second calibrated range without having to perform a calibration procedure. Thus, rather than supporting only a single calibration definition, a calibration memory for the process variable transmitter comprises multiple calibration correction definition entries. Each calibration correction definition entry potentially expresses a correction relationship for one of multiple calibrated ranges represented in the calibration memory.

摘要： A self-evaluating process control transmitter system includes a transmitter configured to capture output data from an integral sensor, and a transmitter memory integrally disposed with the transmitter. The transmitter memory is configured to store a plurality of sets of the output data thereon, including an initial as-built data set, and at least one subsequent data set. A self evaluation module integrally disposed with the transmitter, in communication with the transmitter memory is configured to identify one or more variations between the as-built data set and at least one subsequent data set.
