The PM500 Series catalog series is assigned primarily to pressure measurement module products. Recorded product roles include Pressure Measurement Module. Each listing keeps its complete manufacturer part number and available specifications, so models and accessories remain separate rather than being treated as substitutes.
Within the PM500 Series series, match the complete manufacturer part number; suffixes and separators can identify a different variant.
For PM500 Series, compare the recorded Product family, Instrument class, Product part number, Manufacturer configuration fields on the individual product pages.
For PM500 Series, use the Pressure Measurement Module title and specifications to separate complete devices from modules, accessories or replacement parts.
