Description

1. product description

  The differential pressure transmitter adopted metal sensor.Resistance to overload, bringing function monitoring, have HART, PROFIBUS PA or FF foundation fieldbus communication protocols

2. Advantages

  1. Repeatability and long-term stability

  2. High accuracy: ±0.075%

  3. Range than 100:1,if Special requirements can be higher

  4. Using monitor the flow and differential pressure, The highest conform to SIL3, By TuV SuD, according to the IEC 61508 standard certification

  5. HistoROM®/M-DAT Storage module

  6. The measuring element and electronic module function monitoring

  7. Modular design,that can be exchange with the modular of differential/static pressure and pressure transmitter. (Deltabar S, Deltapilot S, Cerabar S)Can change the display unit Pressure and differential pressure electronic module

  8. Through rapid set menu for quick debugging

  9. Live facilitated operation menu

  10. A wide range of self-diagnosis functions

  Application fields

  1. Deltabar S differential pressure transmitter can solve measurement problems as follows:

  2. Liquid level, volume or mass measurements

  3. Through a number of international certification
