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
•Please make sure that the
transport and storage
temperature of the sensor is
between -40°C to +90°C (-40°F to
194°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.
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 Temperature Sensors
Temperature sensors are used to
measure the temperature of liquids,
gases (including ambient air),
compressed air, and other mediums.
Understanding the temperature your
equipment operates at can help to
prevent issues with equipment
failures, diagnose problems, improve
performance, and optimise efficiency.
Almost every piece of equipment
comes with recommended operating
conditions for optimal performance;
this will certainly include a
temperature range for any input or
cooling mediums such as fluids,
ambient conditions or environmental
considerations.
Temperature sensors can be used in
conjunction with other control
equipment to trigger processes such
as when a specific temperature is
reached or switch on cooling
equipment when systems are starting
to overheat.
About the Sensor
Compressed Air Alliance’s
temperature sensor is easy to install.
The sensor can be suspended in the
ambient environment or the probe
can be inserted directly into the
medium being measured, such as
gases or liquids flowing in pipes.
Calibration requirements
Temperature sensors should be
calibrated every 2 years. Compressed
Air Alliance can arrange calibration
for you.
Permanent and temporary
solutions
Temperature sensors are available
for temporary or permanent
installations.

Step 1 –Find a suitable location for the sensor
The method of mounting or installing the temperature sensor will depend on the
location and the desired measurement.
When installed in pipework, make sure the sensor location has enough room above
the pipe to install the sensor.
Measuring Ambient Temperature
If measuring ambient temperature, the probe should be mounted in a suitable
location with the tip exposed to the ambient conditions and not in direct contact
with anything else.
Measuring Liquid or Gas Temperature
If installing the temperature sensor to measure a gas or liquid temperature careful
attention must be paid to the insertion depth of the sensor.
✓The probe should be inserted into the medium by a minimum of 25 mm or 1”
Do not touch the probe tip with the inner wall of the pipe or conduit.

Incorrect Installation
Connection Point and Compression Fitting
To install the sensor on a pipe or conduit, you need:
•connection point, eg a ball valve or a nozzle or nipple (thread must be G 1/4")
and
•compression fitting.
oThe diameter of the hole must be ≥ 8 mm, otherwise the shaft cannot be
inserted
Use of a ball valve is optional - You do not need to use a valve to install the sensor.
However, using a valve will make removing the sensor easier (eg when you need to
remove the sensor for calibration).
If installing a ball valve, you can use a hot tap drill and clamp to create a connection
point on pressurized or unpressurised pipes. See the Compressed Air Alliance
website for information on hot tap drills and clamps.
Probe is not deep enough
Probe is touching the
inner wall of the conduit
