1. Safety
This sensor must only be installed, used and maintained
by competent personnel. Such personnel shall have un-
dergone training that included instruction on the various
types of protection and installation practices, the relevant
rules and regulations, and on the general principles of area
classification. Appropriate refresher training shall be given
on a regular basis (see EN 60079-17).
The installation, use and maintenance of this sensor must
comply with the appropriate European, national and lo-
cal regulations, which may include reference to the IEC
standards IEC60079-14, IEC60079-17 and IEC60079-19.
In addition, particular industries or end-users may have
specific requirements relating to safety (or health) and
these requirements should also be met. Instructions and
specifications issued by the manufacturer must be followed.
Warning – Use only SPM 18425 battery.
Immediately remove the sensor from Ex-hazardous areas if
safety is questioned or compromised. Return the product
to SPM Instrument AB for examination.
For configuring the Airius sensor, only certified mobile
devices are allowed to be used in Ex-hazardous areas.
The batteries are classified as dangerous goods, when
transported. Transportation of batteries must be in full com-
pliance with the appropriate regulatory provisions. UN3090
is applicable for the batteries and UN3091 is applicable
when the battery is contained in the sensor.

2. Description
The battery-powered wireless sensor AIR01-EX, which ena-
bles wireless condition monitoring in potentially explosive
atmosphere, measures acceleration in three directions,
and temperature. For remote communication, Wi-Fi and
Bluetooth are used. An external push button and three
RGB-LEDs are local user interfaces.
The product enclosure consists of a metal body and an
ESD-protected plastic lid. To enable battery replacement,
the lid is removable. Screw or glue installation on a machine
is performed with an installation foot. Depending on the
installation foot and place of installation, the metal body
may be earthed or unearthed.
There are different versions of AIR01-EX, specified as
AIR01-xy-EX-Szz, where variations do not affect Ex safety.
The letters ‘xy’ denote measurement performance (e.g.
frequency bandwidth) and ‘Szz’ denote variations of op-
erating software.
AIR01-Ex is a member of the Airius family of wireless sensors.
The Airius sensor is compatible with both Condmaster.NET,
the application providing easy access to measurement
data through a user-friendly interface, and the analysis and
diagnostic software Condmaster Ruby.
The SPM Connect app, downloadable for mobile devices,
is used to configure the parameters required for connection
to Condmaster Entity Server (CES) or SPM Cloud.

1Battery cell capacity is 13Wh. Affected by ambient temperature, current profile of load and shelf life above
12 months. Active sensor power consumption increases by Radio (Wi-Fi or BL) low signal strength or high
traffic intensity.
Typical capacity cases:
• Four measurements per day for four years, ±0 to +40 °C, RSSI
≥ −70 dB. Sleeping sensor power consumption is increased by
high ambient temperature.
• Eight years of sensor deep sleep only, ±0 to +40 °C.
The sensor calculates the remaining number of measurements
based on; time from manufacture, time spent in configuration
mode (BL), time between measurements, ambient temperature
and Wi-Fi signal strength (RSSI).
2Battery Shelf Life is 12 months. After 12 months the battery ca-
pacity might be reduced. Ongoing long-time tests are performed,
with the aim to prove an expected longer battery shelf life.

4. Installation of Airius Ex sensor
Installation must only be performed by competent
personnel. There are two methods for installing Airius Ex
sensors, either by screw installation or glue installation.
Position the sensor in such a way that it can optimally
perform measurements while having good Wi-Fi signal
strength.
4.1 Screw installation
1. Drill a screw hole where the sensor should be
placed.
2. Drill a counterbore with 30 mm diameter on the
machine.
3. Align the longest flat side of the installation foot
with the x-axis of the intended measurement direc-
tion.
4. Screw the installation foot onto the machine. See
table for screw torque.
5. Screw the sensor onto the installation foot. See table
for sensor torque.
6. Check that the marking of the sensor aligns with the
intended measurement directions. If the markings
are not aligned with the intended measurement
directions, adjust the installation foot.
NOTE: There are markings for z, x and y on the
sensor, indicating the directions of the measurement.

4.2 Glue installation
1. Drill a counterbore with 30 mm diameter on the
machine where the sensor should be placed.
2. Screw the sensor onto the installation foot. Tighten-
ing torque: 7 Nm.
3. Apply glue (Loctite 326) and activator (Loctite 7649)
to the installation foot.
4. Check that the markings of the sensor align with the
intended measurement directions. Press the sensor
onto the flat surface. Hold steady for three minutes.
NOTE: There are markings for z, x and y on the sen-
sor, indicating the directions of the measurement.

Press and hold the internal push button while the battery
is reconnected. Factory default clears all settings and
reverts to the software installed during factory production.
5.2 Clear settings via the SPM Connect app
Clear settings continue to use the latest software while all
settings are cleared. For more information, see chapter
‘Setting up Airius with SPM Connect’.
