Adopting metal sensor With simulation, HART, PROFIBUS PA or FF fieldbus
Advantages
High repeatability and long-term stability
High accuracy： ±0.15%，Platinum edition: ±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
2. Application feilds
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 125°C (302°F)
Have many certifications, that can satisfied with all required applications in the word.
