MEASUREMENT & MONITORING
SAFE ELECTRICAL SWITCHING
PYROPRESS
Experts in Hazardous Area Instrumentation
Established more than 60 years, Pyropress
is a leading UK based designer and
manufacturer of weatherproof and ATEX/
IECEx certified switches and transmitters for
measuring pressure, differential pressure,
vacuum, temperature, level and flow.
Its quality, reliable and durable products
incorporate proven design techniques and
technology to provide safe and reliable
electrical switching of alarm or control
circuits within flameproof (Exd), Intrinsically
safe (Exia), marine or industrial areas and are
available with SIL2 certification to customers
worldwide.
All ranges are available with SIL2 approval
and have a documented failure rate of 1
failure per million hours of operation. They
have also been certified both IP66 and IP67
in line with the latest standards.
DEVELOPMENTS FOR ATEX AND
IECEX SWITCHES
Pyropress has added new features to its
Perseus range of ATEX and IECEx switches
for use in hazardous areas which is now
available with a stainless steel housing for
the first time.
“We have added an adjustable differential
setting capability to the Perseus range
of Exd flameproof switches and Exia
intrinsically safe switches. It allows fine
tuning of compressor cycling in air
conditioning and HVAC applications
for example and has other uses where
hysteresis control is required,” says Stephen
Burns, Managing Director Pyropress Limited.
“The same module allows two switches
with separate settings. There is also the
option of a second M20 electrical entry.
The Perseus range has been available with
only black anodised aluminium for 10 years
so introducing the stainless steel housing
completes the entire offering.
Pyropress are able to offer custom
switches and transmitters to suit different
applications across all industries and we
hold sufficient stock to manufacture millions
of combinations to suit specific applications.
The Perseus range of switches is
available in pressure, temperature, level
and flow variants and is fully certified
to the European ATEX 2014/34/EU and
International IECEx for explosion proof (Ex
d) and intrinsically safe (Ex ia).
They are available for operating pressures
starting at 0.4 mBar, for ultra low pressure,
vacuum and differential pressure and
reaching 800 Bar on the high pressure
range. Pyropress offers many options and
variants for applications where gas, vapour,
powder and dust are present. For further
details contact us or your nearest Pyropress
distributor.
