PRESSURE RELAY Russian patent published in 2008 - IPC G01L19/12 

FIELD: measuring technique.

SUBSTANCE: pressure relay comprises housing, diaphragm, and lid arranged at a single axis. The housing is made of a rotation body. The lid is provided with outer bushing that receives the inner bushing provided with a glass insulator. The conductor made of a hollow rod passes through the inner bushing. The contact provided at the face of the rod cooperates with the surface of the diaphragm when the relay is set in operation. The position of the contact is determined by the separating diaphragm whose peripheral part is secured to the lid. The central part of the diaphragm is in a contact with the face of the thread stop made of a bushing. The space of the separating diaphragm together with the contact inside it is evacuated through the axial opening in the conducting rod and is sealed by means of welding.

EFFECT: enhanced reliability.
