HDCP series Intelligent Differential Pressure Transmitter is a high-performance pressure transmitter with world-leading technology, developed using an internationally advanced monocrystalline silicon pressure sensor and patented packaging process. It adopts a patented double overload protection diaphragm design and internal circuit surge protection design, which can accurately measure gauge pressure, absolute pressure, flow rate, liquid level and density. Designed with a high level of integration and modular circuit technology, it achieves the functions of remote transmission, local zero and full range adjustment.

Therefore, it can be used in the process control fields of petroleum, chemical, metallurgy, electric power, food, papermaking, medicine, machinery manufacturing, scientific experiment and aviation military industries.

Differential pressure transmitter adopts imported monocrystalline silicon differential pressure sensor as a signal measuring element, digital modular circuit design and digital signal processing technology.

Through testing and calculating pressure difference between the positive chamber and negative chamber, the difference signal is converted into electrical signal output remote transmission.

It can be implemented for a variety measurement of pressure, differential pressure, flow, liquid level, industrial process parameters.

The differential pressure transmitter adopts advanced sensors and signal processing technology, which make it have good anti-interference ability and signal stability.

Simple to operate, easy to install, and the standard 4-20 mA and RS485 signal output is suitable for the digital display table, PLC and DCS system. And it can be used for flow measurement with the associated equipment.
