Seals & Diaphragms
pressure or level of the media in a multi-walled tank, where the separating diaphragm
should be placed close to the inner wall of the tank.
impacts caused by either medium or installation:
- Low or high temperature, increased viscosity, and impurities
- Tendency of crystallisation on the tank walls
- Vibrations of the installation (remote diaphragm seal)
sent to the cooperating pressure measuring device (pressure transmitter, pressure gauge)
through manometric liquid ﬁlling the space between the separating diaphragm of the seal
and the pressure measuring device.
Teflon and tantalum. Several corrosive chemicals, except for hydrofluoric acid, gaseous fluorine and soda lye, can be measured.
Maximum measuring rage 0 … 16bar
Over pressure limit 0 … 250bar
Medium temperature range -30 … 100°C
(petroleum atmospheric residue) in burners and in heat
centres of power boilers.
Maximum measuring range 0...70 bar
Overpressure limit 100 bar
-30...300°C for remote seal
-30...150°C for direct seal
– the ability to take measurements within a narrow range;
– simplicity of assembly.
Type S-Comp, S-Comp51: 0 … 16bar
Type S-Comp 25M: 0 … 250bar
Type S-Comp 10M: 0 … 100bar
Type S-Comp 60M: 0 … 600bar
The model S-P diaphragm seals have a flush diaphragm and are made from 316 stainless steel for a wide range of general applications.
The model S-Ch diaphragm seals have a flush diaphragm and are available in a range of exotic materials for corrosion resistance.
The model S-T diaphragm seals (see picture above) have an extended diaphragm are typically applied to measure the pressure or level of the media in a multi-walled tank.
The model S-Mazut diaphragm seals is applicable to measurement of viscous liquids, at temperatures up to 150°C (300°C when remote diaphragm seal is used).
Product applications - Oil & Gas, Petrochemical, Power, Food, Sanitary and Paper
Suitable for use in - Corrosive atmospheres. Resistant to chemical attack.
