6381 Differential Pressure Transmitter with optional T/RH- standard housing metal by Testo

The differential pressure transmitter testo 6381 was developed specially for monitoring differential pressure in the measuring range from 10 Pa to 1000 hPa. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air. In addition to this, the flow velocity or the volume flow can be calculated from the measurement of the differential pressure in a Pitot tube. Thanks to an optional probe from the probe series 6610, the additional recording of humidity and temperature with one instrument is also possible.

The testo 6381 is particularly outstanding thanks to the automatioc zero-point adjustment which ensures high accuracy and long-term stability.

The integrated self-monitoring and early warning function also guarantees the operator high system availability.

  • Measurement of differential pressure, flow velocity, volume flow; optional: humidity and temperature
  • Automatic zero-point adjustment guarantees high, temperature-independent accuracy and long-term stability
  • Low measurement range up to 10 Pa ensures very high precision at lowest pressures
  • Ethernet, relay and analog outputs allow optimum integration into individual automation systems
  • The P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance
  • Configurable alarm management with adjustable response delay and alarm acknowledgement
