Pressure transmitters for pressure and absolute pressure
Application
These transmitters are used to measure the absolute and relative pressures or the level of liquids and gases, and steam.
They are used in the chemical, pharmaceutical and food industries, in mechanical engineering, shipbuilding, water supply and conservation.
Design
The pressure transmitters contain a thin-film cell with ceramic diaphragm which can be used for corrosive media, and an electronics board, fitted together in a stainless steel housing.
The transmitter has a process connection G½A (male thread), to DIN 16 288 made of stainless steel. The electrical connection is via a plug (DIN 43 650) with Pg 9 cable inlet.
Mode of operation
The transmitters have a thin-film strain gauge which is mounted on a ceramic diaphragm. Every measuring cell is temperature-compensated.
The voltage output by the measuring cell is converted by an amplifier into an output current of 4 to 20 mA.
