Sanitary Diaphragm Seals – Aplisens

The diaphragm seal is a pressure-transmitting, diaphragmtype device. The pressure signal is 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. The diaphragm seal task is to isolate the pressure measuring device from damaging impacts caused by either medium or installation:

• low or high temperature, increased viscosity, impurities;
• vibrations of the installation (remote diaphragm seal);
• pressure fluctuations.

The both S-DIN and S-Clamp types of sanitary diaphragm seals can be used under aseptic conditions. They are typically applied to measure the pressure of media in the food and pharmaceutical industries. Aseptic S-Poziom separator is typically mounted in the bottom parts of tanks. The construction has a diaphragm placed forward and so it does not make a hollow in the surface of the tank bottom part, which eliminates the settling of either the material or washing agent in a connection of the pressure device.
