Products description
Meter provides power circuit for the primary instruments, like pressure transmitter and
others that need power supply availability, measure the output current signal of this
primary instrument the same time, And after operations, interference suppression and
other treatment, Transmit and output isolation of the single-or dual current / voltage
signals, and improve the electrical isolation among input、output and power. It can be used
with  the unit combination meter and DCS、PLC system. It is used widely in Oilfield,
petrochemical, manufacturing, electric power, metallurgy and other major projects.
       All intelligent、digital、programmable;
        Working temperature、zero、full automatic compensation increasing
        High stability, make sure the accuracy be unchanged for years
        High isolation among the power、input、output and two-circuit
        According to international standard of IEC61000
