Abstract
A pressure transmitter for registering the pressure of a medium. The pressure transmitter includes a transmitter body, a dividing membrane attached to the transmitter body forming thereby a pressure chamber, a first pressure canal and a second pressure canal. The two pressure canals exhibit different hydraulic properties.
Claims13
A pressure transmitter, comprising:
- a pressure transmitter body having a top surface;
- a dividing membrane attached to said pressure transmitter body to form a pressure chamber between said top surface and said dividing membrane;
- a first pressure canal, which extends between a first opening in said pressure chamber and a common pressure transfer path;
- and
- a second pressure canal, which extends between a second opening in said pressure chamber and said common pressure transfer path, wherein:
- said second pressure canal exhibits other hydraulic properties than said first pressure canal.

A pressure sensor having:
- a pressure measuring cell;
- and
- a pressure transmitter comprising:
- a pressure transmitter body having a top surface;
- a dividing membrane attached to said pressure transmitter body to form a pressure chamber between said top surface and said dividing membrane;
- a first pressure canal, which extends between a first opening in said pressure chamber and a common pressure transfer path;
- and a second pressure canal, which extends between a second opening in said pressure chamber and said common pressure transfer path, said second pressure canal exhibiting other hydraulic properties than said first pressure canal, wherein:
- said pressure measuring cell is loadable by way of said common pressure transmission path with the pressure prevailing in said pressure chamber;
- and
- said second pressure canal exhibits other hydraulic properties than said first pressure canal.
