Abstract: A pressure measurement device is provided. The pressure measurement device includes a pressure gauge having a hermetically sealed cavity. The cavity includes a pressure transferring media. The materials chosen for both the pressure gauge and the pressure transferring media are selected so that thermal effects on the pressure measurement device are minimized. The pressure transferring media includes a first material and a second material. The material for the pressure gauge and the materials for the pressure transferring media, in particular the first material and the second material, may be selected so that the volume of the pressure transferring media substantially fills the volume of the cavity of the pressure gauge within a particular temperature range. The pressure measurement device includes a pressure reading mechanism coupled to the pressure gauge and operative to convert a displacement of the pressure gauge to a pressure measurement reading.

Abstract: A pressure measurement device is provided. The pressure measurement device includes a pressure gauge having a hermetically sealed cavity. The cavity is filled with pressure transferring media that includes a first material and a compensator material. The first material has a first coefficient of thermal expansion and the compensator material has a second coefficient of thermal expansion that is lower than the first coefficient of thermal expansion. The pressure measurement device includes a pressure reading mechanism coupled to the pressure gauge and operative to convert a displacement of the pressure gauge to a pressure measurement reading.

Abstract: A sensor assembly includes a replaceable sensor module and an assembly housing. The assembly housing contains an assembly housing processor and an electrical connector connected to the processor. The replaceable sensor module has an enclosure adapted to be mounted in a position to sense a process variable, a process variable transducer positioned in said enclosure so as to be exposed to the process variable, and a non-volatile memory having stored therein specific profiling data for the sensor module. The assembly housing processor has data representing a desired sensor assembly output characteristic, and is responsive to receipt of specific profiling data and to the data representing the desired sensor assembly output characteristic to calibrate the sensor assembly to provide the desired sensor assembly output characteristic when connected to the sensor module having the specified profiling data. Radial and axial seals are provided for the openings in the assembly housing.

Abstract: The present invention is an elastic seal for use with a sanitary probe. The elastic seal forms a layer between the probing member and the coating member to eliminate the formation of voids between the two. The elastic seal may include an elastic substance, such as silicon or rubber, to enable it to remain in contact with both the probing member and the coating member in the case that a change in temperature causes either or both to expand or contract. The elastic seal may have a coefficient of thermal expansion that is intermediate to a coefficient of thermal expansion of the probing member and a coefficient of thermal expansion of the coating member. The elastic seal prevents voids from forming in the probe assembly into which outside materials may enter.

Abstract: A measuring device for determining the level of material in a container including a process seal comprising: a substantially conical portion including a narrow end and a wide end, the conical portion terminating at the wide end in a substantially cylindrical outer surface; and a flange portion extending outwardly from the substantially cylindrical outer surface. The process seal minimizes reflection and attenuation of measuring device energy, seals the connection to the container, and meets sanitary standards.
