Abstract: A steam trap monitor includes a process variable sensor configured to sense a process variable related to operation of a steam trap. A memory contains information related to a baseline parameter of the process variable. Diagnostic circuitry calculates a current parameter of the process variable sensed by the process variable sensor and compares the current parameter of the process variable with the baseline parameter. Based on the comparison, the diagnostic circuitry responsively provides a diagnostic output based upon the comparison. The baseline and current parameter are based on a time period during which the steam trap is open or closed.

Abstract: A pressure transmitter includes an isolator mounting assembly for isolating process fluid from an interior cavity of the pressure transmitter. The isolator mounting assembly includes an isolator plug for receiving the process fluid line pressure and coupling the line pressure to a sensor cavity formed by a header joined to a distal end of the plug. A ring member is attached to the header and the distal end of the plug to reinforce the joint formed between the isolator plug and the head. In another embodiment, the isolator mounting assembly includes a base and a support having first and second opposed ends. The first end is rigidly bonded to the pressure sensor while an epoxy joint joins the second end of the support to the base.

Abstract: The present invention relates to a mounting assembly for a pressure sensor in a pressure transmitter. The mounting assembly includes a header having a cavity opening to a first surface. The cavity is defined by an inner endwall and an inner sidewall. A support is joined to the inner endwall within the cavity on a first support end. A pedestal has a first pedestal end supporting the pressure sensor and a second pedestal joined to the second support end. Aligning means align the second pedestal end to the second support end in order that a volume of the mounting assembly is increased to thereby reduce a quantity of fill fluid needed in the sensor cavity.
