 Work 

 VP30 Series pressure transmitter with a new generation of polymer ceramic sensor as a measurement unit, the process pressure directly on the solid corrosion-resistant ceramic diaphragm, the diaphragm will produce elastic displacement, from the substrate between the electrodes and membrane electrode can be detected proportional to the capacitance change with the amount of displacement, capacitance change value by laser trimming circuit amplification, up to 1000 ~ 4000mV output voltage signal, and then converted by the transmitter 4-20mA output. On this basis, integrated microelectronic control technology, the display, transmission, control integration. Human-friendly interface, free to set the parameters, self-tuning, self-diagnostic alarm output, can be achieved up to seven pairs of relay control output contacts, and through HART protocol for remote parameter settings, remote control, self-diagnosis.
