1.the product description
this pressure transmitter adopting ceramic sensors
With simulation, HART and PROFIBUS PA or FF foundation fieldbus communication protocols
Advantages
High repeatability and long-term stability
high accuracy： ±0.15%，Platinum level：±0.075%
Range than: 100:1
Modular design and used to differential /static and gauge pressure. (Deltabar M - Deltapilot M - Cerabar M), ex：
- Can change the display unit
- universal electrical modular
easy to debug，Don't need to use other operating tools
The menu guide operate
– through site display modular
– through 4 ... 20 mA HART
– though PROFIBUS PA
– though FF fieldbus
Cerabar M pressure transmitter can solve the measurement problems as follows：
Measuring the absolute pressure and gauge pressure gas/steam or liquid in all kinds of process control field.
Measuring the level, volume and mass of liquid.
The process temperature can reached to 400°C (752°F)
The pressure can reached to 400 bar
Have many certifications, that can satisfied with all required applications in the word.
