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%.
