testo 6383
Differential pressure transmitter in cleanroom-conform panel design
SPECIFICATIONS
testo 6383
The differential pressure transmitter testo 6383 was
developed specially for monitoring low differential
pressures in the measuring range from 10 Pa to 10
hPa. In cleanroom technology, the maintenance of
positive pressure prevents the entry of contaminated
air in critical zones. Thanks to an optional internal or
external probe from the probe series 6610, the
additional recording of humidity and temperature with
one instrument is also possible.

SPECIFICATIONS
testo 6383
• Measurement of differential pressure; 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
highest precision at lowest pressures
• Flat housing allows flush surface integration in the
cleanroom wall
• Display with multi-language operating menu and
optical alarm display
• Ethernet, relay and analog outputs allow optimum
integration into individual automation systems
The testo 6383 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.
Areas of application:
• Monitoring positive and negative pressure in
cleanrooms, operating theatres and isolation rooms
• Optional monitoring of humidity and temperature in
cleanrooms
Status 12.02.2010
• Self-monitoring of the transmitter and early warning
function guarantee high system availablity
• The P2A software for parameterization, adjustment
and analysis saves time and costs in commissioning
and maintenance
• Scalability of ±50 percent of the measuring range
final value and free scalability within the measuring
range
• Configurable alarm management with adjustable
response delay and alarm acknowledgement

Differential Pressure Monitoring in Cleanroom Technology
Highest accuracy and long-term stability with the new transmitters from Testo
Differential pressure measurement in cleanroom applications

Input air via HEPA/ULPA filter
Typical exhaust air: (50 - 500
air exchanges / h)
Laminar flow e. g.
0.5 m/s
Outside zone
Critical zone
Normal zone
Whether in cleanrooms, greyrooms, OP theatres or
filling systems:
Lowest differential pressures must be maintained
between different rooms or zones in order to prevent
contaminated air from entering.
For this reason, continuous measurement and regulation
of these low differential pressures (according to
cleanroom norm ISO 14644: 5 - 20 Pa) is required.
Annual proof (against zero potential and against adjacent
rooms) of this must be provided according to ISO 14644
.
Functional principle of the automatic zero-point adjustment of the Testo differential pressure transmitter
In hospitals and research laboratories, the pressure
difference (negative pressure) prevents the spread of
germs and dust
Pressure maintenance in cleanrooms
Cleanroom
Automatic zero-point adjustment guarantees highest,
temperature-independent accuracy and long-term
stability
The zero-point stability of differential pressure transmitters
plays a particularly crucial role at lowest pressures (10 Pa
or 50 Pa measurement range). Whereas conventional
differential pressure transmitters require manual readjustment of the zero point, the new transmitter series
from Testo is equipped with an automatic
microprocessor-controlled zero-point adjustment. It
ensures a low level of temperature-dependency of the
pressure sensor, guaranteeing the user high accuracy
and long-term stability.
In the automatic zero-point adjustment, a magnetic valve
causes both sides of the pressure sensor to be exposed
to the same pressure a cyclic intervals. This guarantees
highest accuracy in cleanroom processes!
Positive pressure in the filling room maintains the
hygiene conditions during filling operations in the food
and pharamceuticals industry
Defined pressure differences between cleanrooms and
adjacent rooms ensure quality
