Tongue diaphragm seal 1500 threaded connection Main Features Wetted parts stainless steel 1.4571 (316Ti) Diaphragm with longitudinal starshaped profil Easy and fast installation Applications Water & Waste water Energy Description This tongue diaphragm seals with threaded process connection are used to protect pressure gauges from high temperatures, aggressive or corrosive fluids. Process connection DIN 3852 Type A They avoid that the medium flows into the instrument, where deposits could be built and generate wrong measurements or pollution of the process. Body material 0 ... 1 bar to 0 ... 1000 bar (see table below) Stainless Steel 1.4571 (316Ti) Diaphragm Stainless Steel 1.4571 (316Ti) Bottom Stainless Steel 1.4571 (316Ti) Tongue seals have a large membrane surface in relation to the small connection size. That’s why they can be used for measurement of lower pressure ranges compared to threaded seals with flush diaphragm. Tongue seals should not be used in pipes with strong flow of the medium. Pressure ranges Working temperature -60…200 °C (depending on the filling fluid) Filling fluids LRS1: Vaseline (-15 ... +150 °C) LRS10: Vaseline (-20 ... +225 °C) Other filling fluids on request Chemical seal can be mounted to mechanical pressure gauges, switches or transmitters directly or with a cooling element. The filling fluid of the measuring system has to be choosen compatible to the application.
