QYB400-GP/AP Intelligent Direct Mount Pressure Transmitter adopts monocrystalline silicon sensor chip made of advanced MEMS technology from Germany, which combined with the exquisite production process, realises the high accuracy and ultra-high stability of the product. Embedded with intelligent signal processing module, it realises the perfect combination of pressure and temperature compensation, providing reliable measurement accuracy and excellent long-term stability.
QYB400-GP/AP monocrystalline silicon intelligent direct-connected pressure/absolute pressure transmitter can be used to measure the level, density, pressure of liquid, gas or steam, and convert it into 4-20mA DC (superimposed HART communication) current signal output;
QYB400-GP/AP series products can provide HART/485-Modbus/FF and other communication protocols.
