1.7 Sentro Module
Plug-in pre-calibrated sensing module with standardised output data.
• The sensing module stores all the necessary data about its type identification,
sensing range and specific calibration. This data is automatically recognised by
Sentro Vortex Wireless when the sensing module is loaded into the module
bay
• The sensing modules are pre-calibrated so they can be replaced at any time by
a replacement sensing module
• The sensing module will identify itself when plugged into the sensor housing
and auto configuration will take place
• All Sentro sensing modules have two output alarm signals for General alarm
and High alarm. Default values are entered during manufacture and these can
be changed to preferred values
• The two alarm signals can be set to illuminate built-in flashing LED indicators
• Two auxiliary analogue output signals (4 to 20 mA) to drive a local audio visual
alarm unit, if required

3. Installation
3.1 Tools andTest Equipment
Required
No special tools are required:
• Metric spanner set
• Metric hexagon key set
• Standard electrical test meter
Trolex recommends that the Sentro Wireless
Gas Detector is positioned a minimum of
6 m (20 ft) and no more than 245 m
(800 ft) from a Strata CommTrac C node for
the Sentro Wireless Gas Detector to work
effectively.
Checkpoint
Where the process cannot be interrupted
to remove the Sentro Vortex Wireless
from a pipeline, an isolating ball valve
may be fitted to the process connection
at the installation. This is also useful
in installations that have a high level
of contamination or moisture in the air
stream. Build up of debris or water vapour
will cause deterioration of the output
signal.
3.2 Siting Recommendations
3.2.1 Fitting in Pipes and Ducts
To attain the best accuracy of response,
select a position that is at least twenty pipe
diameters down-stream from bends or
obstructions, and approximately five pipe
diameters from down-stream intrusions.
Similarly, the sensor should be mounted
www.trolex.com

TX5952 User Manual
TX5952-UM-EN-01a 15
at least fifteen pipe diameters from a pipe
reducer and fifty pipe diameters from valves.
If this is not possible then the installation
of a standard flow straightener will improve
performance.
Fit a corresponding threaded boss or flange
at the monitoring point and install the sensor,
ensuring a air tight seal.
Checkpoint
High pressure versions, above 2 bar, will be
supplied with a welded bush or flange and
will require dedicated process fittings.
Release the clamping ring on the mounting
bush or flange.
The centre of the flow path of the sensing
head should be positioned as shown.
Checkpoint
Ensure that pressurised systems have
been completely vented before installation
or removal of the sensor.
Position the sensing head with the smaller
opening facing the flow, within a rotational
deviation of no more than 12.5° from the
axis of flow. Tighten the clamping ring with
moderate force.
Avoid fitting the sensor at low points
in pipework structures to prevent the
sensing head from being affected by large
accumulations of moisture.

3.2.2 Fitting in Roadways and
Tunnels
To attain the best accuracy of response,
select a position away from adjacent
structures with a clearance of at least 200
mm.
The version with a side projecting sensor can
be mounted on to a suitable support using
the mounting holes.
Alternatively use a standard mounting bush
or flange for fitting to a suitable bracket.

3.3 Connections
The Sentro Vortex Wireless is battery
powered and has wireless communications,
therefore no wiring is required to install it.
However, there are two analogue output
signals. These can be used to connect to
local audio visual alarms, if required.
If you decide to use local audio visual alarms
you will need to wire them to the Sentro
Vortex Wireless. Connections are as follows:
1. Alarm output 1
2. 0 V
3. Alarm output 2
4. Battery + V (no user connection)
5. 0 V Battery - V (no user connection)
6. Reserved for future use (no user
connection)
The terminals are located behind the front
cover. Use a cross head screwdriver to
remove the four screws securing the front
cover and move it out of the way.
