In typical processing plants, a communication bus, such as a 4-20 mA current loop is used to power the process variable transmitter. Examples of such current loops include a FOUNDATION� Fieldbus connection or a connection in accordance with the Highway Addressable Remote Transducer (HART) communication protocol. In transmitters powered by a two-wire loop, power must be kept low to comply with intrinsic safety requirements.
One technique which has been used in situations in which power is not a constraint is described in U.S. Pat. Nos. 5,713,668 and 5,887,978, issued Feb. 3, 1998 and Mar. 30, 1999, respectively, to Lunghofer et al. and entitled �SELF-VERIFYING TEMPERATURE SENSOR� each of which is herein incorporated fully by reference. These references describe a temperature sensor having multiple outputs. The multiple outputs all vary as functions of temperature. However, the relationships between the various outputs and temperature are not the same. Further, the various elements in the temperature sensor change over time at differing rates, and in differing manners and react differently to various types of failures. A computer monitors the output from the sensor using a multiplexer. The computer places data points from the sensor into a matrix. By monitoring the various entries in the matrix and detecting changes in the various element or elements of the matrix relative to other elements, the computer provides a �confidence level� output for the measured temperature. If the confidence level exceeds a threshold, an alarm can be provided.
FIG. 3 is a system block diagram of process temperature transmitter 12 in accordance with an embodiment of the invention. Process temperature transmitter 12 includes an analog to digital converter 20 configured to provide a digital output 22 in response to an analog input 24. A two-wire loop communicator 26 is configured to couple to two-wire process control loop 16 and to send information on loop 16 from a microprocessor 28. At least one power supply 30 is configured to couple to loop 16 to receive power solely from loop 16 and provide a power output (Pwr) to power circuitry in transmitter 12 with power received from loop 16. A temperature sensor 34 couples to analog to digital converter 20 through multiplexer 36 which provides the analog signal 24. Temperature sensor 34 includes temperature sensitive elements such as RTD 40 and thermocouples 42, 44 and 46. Temperature sensor 34 operates in accordance with the techniques described in U.S. Pat. No. 5,713,668. In addition to the transmitter shown in FIG. 3, the teachings of U.S. Pat. No. 5,828,567 to Eryurek et al., entitled �DIAGNOSTICS FOR RESISTANCE BASED TRANSMITTER� can be used with sensor 34, which patent is herein incorporated fully by reference.
Analog to digital converter 20 operates under low power conditions. One example of analog to digital converter 20 is a sigma-delta converter. Examples of analog to digital converters used in process variable transmitters are described in U.S. Pat. No. 5,803,091, entitled �CHARGE BALANCE FEEDBACK MEASUREMENT CIRCUIT� issued Jan. 21, 1992 and U.S. Pat. No. 4,878,012, entitled �CHARGE BALANCE FEEDBACK TRANSMITTER, issued Oct. 31, 1989, which are commonly assigned with the present application and are incorporated herein by reference in their entirety.
