Description
The Testo 6381 differential pressure transmitter is uniquely engineered to perform complex monitoring tasks, automatically calculating volume flow and flow velocity directly from differential pressure data. Operating across a measuring range of 10 Pa to 1000 hPa, it utilizes an advanced automatic zero-point adjustment to achieve excellent temperature-independent measurement stability over long intervals. It features a scalable alarm management module and supports direct integration with Testo 6610 probes for optional humidity and temperature expansion.
Industrial Applications
- Maintaining precise positive pressure cascades and flow parameters within critical cleanroom architectures
- Automated pressure and flow monitoring inside industrial drying and high-volume evaporation processes
- Differential pressure optimization across high-accuracy product filling systems and commercial spray-painting lines
