PCD-S - RMS Differential Pressure Probe

The Rotronic differential pressure probes are ideal for clean rooms, operating theaters and applications where even minor differences in pressure can have a big effect. Thanks to our two different measurement methods (thermal mass flow measurement and diaphragm measurement), we offer the perfect solution for every requirement. Together with other measurement parameters, these probes can be integrated in RMS perfectly.


  • High-precision measurement and long-term stability
  • With ambient pressure compensation
  • Large overload range
  • With flow or diaphragm sensor technology
  • Compatible with RMS logger, RMS On-premises software and SaaS solutions


  • HVAC
  • Cleanroom
