Application The diaphragm seal is a pressure transmitting, diaphragm-type 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: s High corrosiveness s Low or high temperature, increased viscosity, and impurities s Vibrations of the installation (remote diaphragm seal) The material...
