Intelligent differential pressure transmitter
The intelligent differential pressure transmitter transmits two kinds of pressures into the high and low pressure chambers,
acting on the isolating diaphragms on both sides of the delta component (ie, the sensitive component), through the spacer
and the filling liquid in the component. Transfer to both sides of the measuring diaphragm. The measuring diaphragm and
the electrodes on the insulating sheets on both sides each constitute a capacitor. When the pressures on both sides are
inconsistent, the measurement diaphragm is displaced, and the displacement is proportional to the pressure difference,
so the capacitance on both sides is not equal, and is converted into a signal proportional to the pressure through the oscillation
and demodulation links.
The intelligent differential pressure transmitter is used to measure the liquid level, flow and pressure of liquid, gas or steam
under high working pressure, and then converted into 4~20mA DC signal output. The intelligent type can communicate with the
HART Communicator to set, monitor or form a field monitoring system with the host computer.
10. Standard 4-20mA with digital signal based on HART protocol, remote control supports upgrade to fieldbus and field
control based technology.
Attention of when you ordering :
4. If the differential pressure transmitter needs to be equipped with a three-valve group and a throttling device,
it needs to be separately indicated.
5. The transmitter is calibrated according to the range specified by the user. If the user does not specify, the transmitter is
tuned to a large range of Max, this calibration will be carried out at room temperature and atmospheric pressure.
6. When the station number needs to be marked, it should be indicated when ordering.
