The GP:50 product line of melt pressure transducers and transmitters is based on the proven bonded strain gauge principle successfully utilized in thousands of applications. GP:50's unique design incorporates a heavier sensor allowing a thicker tip diaphragm, provides better linearity, and reduces costs. The design incorporates an extremely small capillary tubing that transmits the media pressure to the strain gauge sensor and mating electronics via a mechanical fill fluid. (Mercury is the standard, silicone and mineral oil are readily available depending on the application). GP:50 Melt-Kits come with everything you need for efficient and reliable extrusion pressure measurement. Melt-Kits include transducer, cable, indicator and more.
