UPB12 differential pressure transducers/transmitters are assembled by using OEM silicon piezoresistive pressure sensors. UPB12's housing is made of aluminum alloy structure, and the products can be installed on the pipelines directly, or connected through pressure pipes. UPB12 differential pressure transducers/transmitters are featured with high stability, good dynamic performance. The non-linearity and temperature drift of the transducers can be compensated by equiped a high performance microprocessor, and also realize such functions as precise data transmission, field apparatus diagnosis, long-distance two-way communications and so on. The output signals of UPB12 have mV, V, or mA, as well as frequency output for options.
UPB12 are suitable for measurement & control for almost kinds of liquids and gas.They are widely used for pressure process & control in electric powers and coal mining pressure such as for boiler air supply and ventilation of mine etc.
Features:
*Using imported sensitive chips and high performance special-purpose circuit
*Strong ability of anti-interference, and good long term stability
*Full scope compensation for zero & sensitivity
*Have mV output signal, and standard Volt or mA output signal for options
*With many different outer structures
