Abstract: A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.

Abstract: A process variable transmitter (10) includes an analog-to-digital (A/D) converter (22) that receives a sensor signal (20) provided by a sensor (18) that senses a process variable and converts the sensor signal (20) to a digital signal. A processor (24) receives the digital signal and provides a measurement output indicative of the digital signal. A noise detector (26) receives the sensor signal (20) and generates a first value indicative of a number of positive noise events relative to a positive threshold value and a second value indicative of a number of negative noise events relative to a negative threshold value. The processor (24) evaluates the noise count and generates a noise output, indicative of detected noise, based on the first and second values.

Abstract: A process temperature transmitter (12) is operable with at least one temperature sensor (32) having a plurality of leads. The temperature transmitter (12) includes measurement circuitry (26) operably coupleable to the at least one temperature sensor (32) to provide an indication of an electrical parameter of the at least one temperature sensor (32). A controller (30) is coupled to the measurement circuitry (26) to obtain the indication and provide a process temperature output. A current source (28) applies a test current to the plurality of leads simultaneously. Diagnostic circuitry (70) measures a voltage response on each lead in order to provide a diagnostic indication of the temperature sensor.

Abstract: An apparatus (12) for measuring a temperature of a process fluid includes a resistance based temperature sensor (RTD) sensor (32) configured to thermally couple to the process fluid. First and second electrical connections are configured to apply a current through the RTD (32). Measurement circuitry (36) is configured to measure a voltage across the RTD (32) and identify a degraded connection to the RTD and responsively measure a temperature of the process fluid using the electrical connections.
