Signal elements which are used for pressure measuring in pressure lines for gases, vapours, liquids or suspensions. The switch points are transformed into a binary electric or pneumatic output ** which is necessary for the control and regulation of processes, e.g. safety and alarm devices.
Pressure Gauges
Mechanical pressure indicators. The actual process pressure acts on a measuring element and deforms it. The deformation is converted into a 270° rotating motion by the attached movement. Due to the electricity-free function, pressure gauges even remain fully functional in most total damage occurance
Pressure Transmitters
Electronic pressure instruments that transform process pressure into an electrical **. The ** is proportional to the applied pressure and changes according to the pressure change. Output **s could be either voltage or current and are used for controlling processes or for archiving process data.
Diaphragm Seals
Mechanical process separating elements which are mounted on measuring instruments directly or via capillary; with diaphragm seals the measuring instrument is separated from the actual process to protect the instrument from hot, polluted, aggressive or chrystalizing media.
