GP:50 Corporation Ltd.’s Model 188/288/388 miniature flush diaphragm pressure transducer series’ unique flush diaphragm design makes possible accurate pressure measurements of high-viscosity fluids, even within high shock and vibration environments, without port plugging and clogging. According to the company, this makes the series particularly useful for the support of automotive and aerospace test stands, chemical processing, and plastics extrusion as well as adhesive, sealant, and paint systems. The GP:50 Model 188/288/388 series features an all-welded stainless steel construction and incorporates a 7/16-20 UNF pressure port that eliminates any zero installation effect. Standard wetted parts are made from stainless steel with optional substitution of Inconel or Hastelloy. The standard operating temperature range for the Model 188/288/388 is -65  to +250°F (-54 to +121°C) with an optional high-temperature version to +350°F (+177°C).
