Compressed Air
Safety
Any contact with quickly escaping air
or bursting parts of the compressed
air system can lead to serious injuries
or even death.
•Do not exceed the maximum
permitted pressure.
•Only use pressure rated
installation materials and parts.
•Avoid getting hit by escaping air
or bursting parts.
•The system must be pressure-
less during maintenance work.
Electrical Safety
Any contact with energised parts of
the product, may lead to an electrical
shock which can lead to serious
injuries or even death. The user shall
take all measures necessary to
protect against electrical shock.
Consider all regulations for electrical
installations.
The system must be disconnected
from any power supply during
maintenance work.
Any electrical work on the system is
only allowed by authorised qualified
personal.
Storage and transportation
•Make sure that the
transportation temperature of
the sensor is between
-10°C to 60°C (14°F to 140°F).
•Please make sure that the
storage temperature of the
sensor is between -10°C to 50°C
(14°F to 122°F) and the humidity
is <90%, no condensation. Avoid
direct UV and solar radiation
during storage.
Cleaning
If you need to clean the sensor it is
recommended to use a clean, dry
cloth. For stubborn marks, use
distilled water or isopropyl alcohol
only.
Please note: contamination on the
sensor tip will affect calibration and
accuracy of the sensor. Removal of
the contamination may not fix the
issue.
Disposal
Electronic devices are recyclable
material and do not belong in the
household waste. The product,
accessories and its packing material
must be disposed according to local
statutory requirements.

About Dew Point Sensors
When it comes to monitoring
compressed air and gas systems,
nothing offers a better payback than
a dew point sensor. Once you have
moisture in your system, everything
becomes a problem. If you have ever
had this occur, you'll know the
problem occurred days before you
discovered it and it took even longer
to dry out after the issue was fixed.
Most people don't think of dew point
sensors as providing efficiency, but
wet compressed air or gases will do
irreparable damage to components,
create reliability issues throughout
your entire plant and allow bacteria,
rust and corrosion to build up in your
system. Moisture issues are
extremely difficult to rectify and
component failures will go on for
years.
If you have a system running a
desiccant dryer or with a specified
purity requirement, then you are
already aware that dew point is a
critical component of your system
and therefore should be monitored
continuously.
Indicators on refrigerant dryers
don’t measure dew point
The indicator on your refrigerant
dryer is exactly that, an indicator, it is
not measuring the dew point
entering your plant. It is only
measuring the temperature of the
refrigerant gas. Any number of issues
before and after your dryer can lead
to the dew point deteriorating and
will not be shown on the dryer
indicator.
Compared to your compressed air or
gas system, dew point sensors are
cheap, easy to install and have low
maintenance requirements. They are
the most cost effective sensor
purchase you are ever likely to make.
Benefits of monitoring dew point
•Improve system reliability
•Reduce product contamination
risks
•Reduce system maintenance
•Reduce operating and energy
costs
•Reduce the risk of rust and
corrosion build up
•Improve dryer reliability
•Improve filter life and
performance
•Reduce the risk of bacteria,
fungus and yeast build up
•Alerts you to changes in dryer
performance before moisture
appears in your plant
•Easy to install and low
maintenance
•Suitable for temporary or
permanent installations.
