    Abstract: A pressure transmitter (50) with an output (88) predicting the magnitude of error in the pressure transmitter's output (57). A pressure sensor (72) is adapted to sense a process pressure (74). A controller (76) coupled to the pressure sensor (72) generates a transmitter output (78) representing the process pressure (74). A memory (80) stores predetermined data predicting magnitudes (82) of transmitter output error as a function of cumulative excessive sensor output levels, and also stores a record of cumulative excessive sensor output levels (86). The controller (76) calculates a predicted present magnitude of transmitter output error as a function of the accumulated record and the predetermined data, and generates the prediction output (88).

    Abstract: A transmitter (22) in a process control loop (34) includes a sensor (40) for sensing a process variable. An analog-to-digital converter (42, 44) coupled to the sensor (40) provides a digitized process variable at various sample times. An interface (54) couples the transmitter to the control loop (34) and is used for communicating information and receiving power over the control loop (34). The transmitter (22) includes a clock (52) and a memory (50). A microprocessor (48) coupled to the clock (52) and the memory (50) stores digitized process variables and clock information in the memory (50).

    Abstract: A circuit (58) for compensating variables in a measurement transmitter (2). Within the transmitter, a sensor (54) senses a primary process variable such as differential pressure and a converter (56) digitizes the sensed process variable. The sensor (54) senses pressures within a span of pressures values. A memory (68) inside the transmitter stores at least two membership functions. The memory (68) also stores a set of compensation formulas, each formula corresponding to a membership function. A selection circuit (64) in the transmitter (2) selects those membership functions which have a non-zero value at the digitized PV, and a correction circuit (66) provides at least one correction value calculated from a compensation formula corresponding to a selected membership function. A weighting circuit (70) multiplies each correction value by its corresponding selected membership function, and combines the multiplicands to provide a compensated PV. The compensated PV is coupled to a control circuit (6) connecting the transmitter (2) to a control system (4).

    Abstract: In this invention, a valve positioner (50) receives a setpoint from a master (62) and provides a control pressure to a valve actuator (70) for controlling a valve (72).
