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 and Test 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

14

TX5952-UM-EN-01a

www.trolex.com

www.trolex.com

TX5952 User Manual
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.
TX5952-UM-EN-01a 15

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.
