A through the installation of pipes or vessels in the remote device to feel pressure to be measured and remote transmitting pressure and differential pressure transmitter, the pressure by capillary filling filled with silicone oil (or other liquid) transfer to the transmitter of the subject and the send delta room in the main body of the device and amplification circuit board, will be converted to pressure or differential pressure, 4 - 20mA.Dc signal output 1151hp type high pressure differential pressure transmitter.
Product composition
Remote transmitting pressure, differential pressure transducer and intelligent plate combination, constitute the intelligent remote pressure, differential pressure transmitter, and conform to the HART protocol of the manipulator with, can communicate with each other, setting up and monitoring. In order to adapt to the different installation requirements, the series transmitter with various forms of remote device for users to choose. The main structure and differential pressure transmitter, pressure transmitter.
working principle
Inconsistent, when the capacitance of capacitor equal to the pre Delta in two of the measured medium pressure into high and low pressure chamber, the role of components (i.e. sensitive element) on both sides of the diaphragm, the diaphragm and delta element within the filling liquid tension measuring wax slices on both sides, measuring diaphragm and on both sides of the insulator electrode, a capacitor, no pressure or pressure measuring diaphragm in the middle position, both sides is equal to the amount on both sides of the pressure, thus the measuring diaphragm displacement, the displacement and the pressure difference is proportional to, so both sides of the capacitor is unequal, the detection, amplification and conversion into 4-2OmA second tier current signal.
