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 product it is
recommended to use a clean, dry
cloth. For stubborn marks, use
distilled water or isopropyl alcohol

About Dew Point Sensors
Dew Point Sensors are the simplest way
to monitor dryer performance and
detect moisture issues before they can
cause a problem.
Moisture in the gas systems can clog
pipes, break machinery, cause
contamination (eg rust, mildew, bacteria)
or cause freezing.
Compressed Air Alliance’s dew point
sensors are designed for measuring
pressure dew point, gas temperature,
relative humidity and pressure (optional)
in manufacturing, industrial and base
building environments.
Dew point sensors are cheap, easy to
install and have low maintenance
requirements.
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.
