Diaphragm flanges - Import export

Industrial pressure measurement covers a very wide range of gases and liquids. The physical and chemical properties of these products sometimes make them incompatible for contact with the sensing elements of pressure gauges or transmitters. In such cases the measuring instrument must be separated from the pressurized fluid by a system capable of transmitting the pressure to this instrument while isolating it from the fluid itself. This system is known as a diaphragm seal. Bourdon offers a wide range of diaphragm seals for nearly all applications and industries. Do not hesitate to contact our specialists to find the best solution for your application.

The stainless steel probe LMK 382 has been designed for continous level measurement in waste water, waste and higher viscosity media. Basic element is a robust and high overpressure capable capacitive ceramic sensor e.g. for low levels easily. Features: — nominal pressure: 0 ... 40 cmH2O up to 0 ... 200 mH2O — accuracy: 0.35 % (opt. 0.25 %) FSO — diameter 39.5 mm — especially for sewage, viscous and pasty media Optional Features: — IS-version Ex ia = intrinsically safe for gas and dust — mounting with stainless steel pipe — flange version — diaphragm pure ceramic (99.9 % AI2O3) — different kinds of cables — different kinds of elastomers

The stainless steel probe LMK 382H has been designed for continous level measurement in waste water, waste and higher viscosity mediums. Basic element is a robust and high overpressure capable capacitive ceramic sensor e.g. for low levels. Features: — nominal pressure range 0 ... 60 cmH2O up to 0 ... 200 mH2O — accuracy: 0.1 % FSO — diameter 39.5 mm — HART®-communication (setting of offset, span and damping) — permissible temperatures up to 85 °C — high overpressure capability — high long term stability Optional Features: — IS-version Ex ia = intrinsically safe for gas and dust — mounting with stainless steel pipe — flange version — diaphragm pure ceramic (99.9 % AI2O3) — accessoires e.g. assembling and probe flange, mounting clamp
