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.

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

Optimizing processes and saving time in commissioning and maintenance

The Testo transmitters are delivered ready to use. For
professional application, the following functions are available
via the easy-to-use software:

–Parameterization of unit and scale
–Sensor adjustment and adjustment of the analog outputs

(humidity: 1-point, 2-point; pressure: n-point)

–Parameterization and adjustment history of all activities of the

P2A software are registered in the PC

An adjustment of the entire signal chain is possible directly at
the measurement site thanks to the external interface.
This saves time in commissioning and maintenance.

In addition to this, complete parameter files can be stored in
the PC. The parameterization of spare transmitters or similar
measuring points is thus possible with minimal time
expenditure.

Ethernet networking

– Integration of the transmitters into customers’ Ethernet network
– Integration of the transmitters into measurement data monitoring systems, e.g. testo Saveris

TM

Using the P2A software, unit and scale can be easily parameterized, for example

Differential pressure transmitters for installation in normal zones

testo 6381– Overview of features and

benefits:

· 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

· The robust metal housing protects from tough
ambient conditions

· Combination of differential pressure, humidity,
and temperature measurement in one
instrument saves investment costs
(exchangeable digital humidity probe see
page 10)

·

Display with multi-language operating
menu and optical alarm display

· Ethernet, relay and analog outputs allow
optimum integration into individual automation
systems

· Self-monitoring of the transmitters guarantees
high system availability

· The P2A software for parameterization,
adjustment and analysis saves time and costs
in commissioning and maintenance

· Scalable measuring range by ±50 percent of
the measuring range final value, and free
scalability within the measuring range, allow
optimum adaptation to the control
requirements

Areas of application:

· Differential pressure monitoring between
cleanrooms (optional: simultaneous
measurement of ambient temperature and
humidity)

· Monitoring drying processes

· Differential pressure monitoring in filling
processes and spray-painting systems

Ethernet module
(Intermediary layer)

Ethernet

The Ethernet module is an
intermediary layer („sandwich“
design), which can be optionally
integrated into the transmitters
testo 6681/6351 ex-works. It can
also be subsequently easily and
quickly retrofitted on site. Two
LEDs provide the responsible
system operator with information
on the status of the voltage
supply and the LAN connection.

The cable can be used to carry
out an adjustment of a humidity
probe from the probe series testo
6610 - either on site or in a
laboratory. The cable also serves
as an extension between the
transmitter and the respective
probe.

Advantages of the adjustment

By using an industrial Ethernet
plug, IP65 housing protection can
be guaranteed, enabling the
transmitter to withstand the
sometimes rough and demanding
conditions in industrial processes.

and extension cable:
– Flexible installation and

maintenance of the humidity
probe

– Extension of the normal

humdity probe cable by 10 m

– Cable has protection class

IP65
