    Abstract: A method includes sensing a process parameter to generate a sensor signal that includes a process signal and line noise components, digitizing the sensor signal at a sample rate, detecting line noise zero crossings in the sensor signal, determining a line noise frequency as a function of the detected line noise zero crossings, and adjusting the sample rate as a function of the line noise frequency to reduce an impact of line noise on the digitized sensor signal.

    Abstract: An infrared sensor includes a thermopile connected in series with an ambient temperature compensation resistance temperature detector (RTD) and four electrical leads. The thermopile produces a voltage as a function of temperature of a point of interest, while the RTD varies in resistance as a function of ambient temperature. Two of the leads deliver current to energize the RTD. The other two leads are used for sensing voltages produced by the thermopile and the RTD.

    Abstract: A display assembly includes a transparent cover piece, a display shroud having a contact structure arranged to face the transparent cover piece, an interface subassembly mounted on the display shroud, an electronics board shroud having a support member and a connection feature, and a biasing member operably engaged between the display shroud and the electronics board shroud. The connection feature mechanically connects the electronics board shroud to the display shroud while permitting axial displacement and rotation therebetween. The biasing member rests on the support member of the electronics board shroud, and the biasing member is configured to urge the contact structure of the display shroud into physical contact with the transparent cover piece. The interface subassembly includes a display circuit for providing a digital display and a touch circuit for providing touch actuation at or near the digital display through the transparent cover piece.

    Abstract: A system for measuring temperature includes a thermowell, a primary temperature sensor, a reference sensor, and a transmitter. The thermowell has a measurement instrument connection and a side port. The primary temperature sensor extends into the thermowell through the measurement instrument connection, and the reference sensor extends into the thermowell through the side port. The transmitter is connected to each of the primary temperature sensor and the reference sensor. The transmitter has circuitry for measuring temperature based upon signals received from the primary temperature sensor and for concurrently calibrating based upon signals received from the reference sensor.
