7MF15654 Pressure Transmitter, PSIG Range for Sensing Liquid/Gas Technical Instructions
Document Number 155-768
September 16, 2021
Siemens Industry, Inc. Page 3
Measuring range ≥1 bar
(≥14.5 psi)
The thin-film measuring cell has a thin-film resistance bridge to which the operating
pressure p is transmitted through a ceramic diaphragm.
The measuring cell output voltage is converted by an amplifier into an output current.
The output is linearly proportional to the input pressure.
