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
Dierential pressure transmitter
with humidity/temperature option
testo 6381
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.

* The determination of measurement uncertainty takes
place according to GUM (Guide to the Expression of
Uncertainty in Measurement):
For the determination of measurement uncertainty, the
accuracy of the measuring instrument (hysteresis, linearity,
reproduceability), the uncertainty contribution of the test site as
well as the uncertainty of the adjustment site (works calibration)
are taken into account. For this purpose, the value of k=2 of the
extension factor, which is usual in measurement technology is
used as a basis, which corresponds to a trust level of 95%.
