The 3D diaphragm pressure gauge is used to measure the pressure of neutral and aggressive media. The manometer is hermetically separated from the media by a diaphragm made of PTFE-TFM 1700 to protect it against the corrosive affects of the media. The pressure is measured through a buffer fluid that transfers the pressure onto the measuring chamber of the manometer. The large surface of the diaphragm ensures high-precision measurement results.
