Description
430S-series pressure transmitters are designed for low pressure applications and made of silicon
piezoresistive technology. When a working pressure acts on the metal diaphragm, the pressure is transmitted
to a Wheatstone bridge circuit of the pressure sensor die (SE103) through filling fluid. The output signal of the
bridge circuit, which is proportional to the working pressure, is processed further to fit application purpose by
a signal conditioning circuit.
The pressure range of the 430S transmitters starts from -0.1-+1 bar and ends to 0-1 bar. A number of
standard output signals, such as 4-20 mA current loop or voltage output of 0.5-4.5V or 0.5-5V (or 10V), are
available when order. The measuring accuracy of 430S transmitters is 0.5%fs (fs=full scale). Thanks to BCM's
advanced temperature compensation technology and aging process, model 430S transmitters provide rather
good long-term stability (<0.2%fs/year) and excellent thermal characteristics (<0.03%fs/°C).
