Product Description

Modbus 4 20mA HART best price 0.1 0.05 0.075 accurcy pressure transmitter 

Product Description

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.
 

Applications

1. Petroleum/chemical/fossil              

Used in conjunction with throttling devices to provide accurate flow measurement of pressure and level in pipelines and storage tanks.

     2.Electric power/city gas

Require high stability and high accuracy of pressure, flow, level measurement and other places.

 
    3.Pulp/Paper                   

Used for pressure and negative pressure measurement of storage tanks and other places requiring high stability and accuracy.

   
   4.Steel/Nonferrous Metals/Ceramics          

For pressure, flow and level measurement of chemical and corrosion resistant liquids.

   
  5.Mechanical equipment/shipbuilding               

Used in places where stable measurement is required under conditions of strict control of pressure, flow, and liquid level indicators.
 

     Main features

1. High precision grade                    

German high precision monocrystalline silicon sensor chip, accuracy up to ±0.05%.

1. Strong load resistance                
2. Excellent environmental adaptability                  

Intelligent pressure compensation and temperature compensation eliminates the transmitter from being affected by temperature and minimises the comprehensive test error on site.

1. Excellent long-term stability                 

Stability can be maintained at 0.1%FS/5 years.

1. Flexible remote assistance commissioning function             

Through Hart, FF bus, RS485 communication and panel keys to achieve remote and local parameter setting function configuration.
