Product 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 -30~+30 mbar and ends to -600~+600 mbar. A number of standard output signals, such as 4~20 mA current loop or voltage output of 0.5~4.5 V or 0.5~5 V (or 10V), are available when order. The measuring accuracy of 430S transmitters is 0.5%fs (fsfull scale). Thanks to BCMs 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%fso/C).
The all-welded stainless steel construction of 430S PTs allows them to have better media compatibility. Various mechanical interfaces and electrical interfaces are available. These interfaces can be combined without limitation.
By means of an inner cavity, model 430S transmitter is designed to measure low gauge or absolute pressures of gases or dilute liquids. The all-stainless steel construction allows 430S transmitters to have a compatibility of pressure media with SS 316L. 430S transmitters are especially suitable for medical applications.
