Remote differential pressure transmitter that is, when the differential pressure transmitter and the equipment to be measured with a capillary connection that is to become a differential pressure transmitter with remote transmission, is a kind of installed in the pipeline or container on the remote transmission device to feel the pressure to be measured, the pressure by the capillary tube filled with silicone oil (or other liquids) to the body of the transmitter, and then by the transmitter body of the δ-chamber and the amplifier circuit board, will be converted into 4 ~ 20mADC signal (superimposed HART digital communication or PROFIBUS-PA communication signal output, and with the HART protocol operator to comply with the HART protocol, the operator can be used as a remote transmitter, and then the transmitter is used as a remote transmitter. 20mADC signal (superimposed with HART digital communication) or PROFIBUS-PA communication signal output, and cooperate with the hand manipulator conforming to HART protocol, can communicate with each other for setting and monitoring.
ZDS4833 Differential Pressure Transmitter (Flat Diaphragm Type) has various forms of remote transmission devices, the main structure is the same as the differential pressure transmitter, used to measure the liquid level, widely used in petroleum, chemical, electric power, food, paper, municipal engineering and other industries.
