SENTRO GAS SENSOR/TRANSMITTER<br />
sentro modules...<br />
There is a wide choice of sensing modules and each one stores all the<br />
necessary data about its type identification, sensing range and specific<br />
calibration. This data is automatically recognised by SENTRO when the<br />
eModule is plugged in.<br />
4000 points of date-stamped measurements are also logged and can be<br />
reviewed by connecting the module to a USB port of a standard PC.<br />
The service history of the module and the condition of the sensing<br />
element are also recorded.<br />
The eModules are pre-calibrated so can be substituted at any time by a<br />
replacement module – usually of the same type, but an alternative may<br />
be inserted if required.<br />
Security coding can be used to ensure that the same type of SENTRO<br />
eModule is always used.<br />

TOXIC GASES • ELECTROCHEMICAL CELLS<br />
SENTRO eModule for monitoring toxic <strong>gas</strong>es present in the environment using<br />
electrochemical cells, combining good sensitivity at low <strong>gas</strong> concentrations with<br />
high range capability and excellent stability.<br />
The cells have a natural life of about two years, dependent upon monitoring<br />
conditions and the module can be quickly replaced and serviced at the end of its<br />
working life.<br />
Toxic <strong>gas</strong> SENTRO eModules have very low power consumption so enabling the<br />
4...20mA two wire, line powered version of SENTRO (TX6352) to be used when<br />
preferred.<br />

SENTRO eModule<br />
FLAMMABLE GASES • POISON RESISTANT CATALYTIC SENSOR<br />
SENTRO eModule utilising a poison resistant catalytic combustion <strong>sensor</strong> to<br />
monitor flammable <strong>gas</strong>es present in the atmosphere. The <strong>sensor</strong> will respond to<br />
most flammable <strong>gas</strong>es and vapours to varying degrees; it is normally calibrated<br />
to methane in terms of %LEL or %volume. Very good sensitivity at low levels of<br />
concentration but not suitable for use above the LEL level. Calibration for other<br />
flammable <strong>gas</strong>es can also be provided.<br />
The relatively large mass of the sensing element assures a long and reliable<br />
operating life with exceptional stability, even in conditions of high vibration.<br />
The natural life of the <strong>sensor</strong> is about five years depending upon the monitoring<br />
conditions and the module can be quickly replaced and serviced at the end of its<br />
operating life.<br />
TX6350.240 Methane 0...100% LEL<br />
Can also be calibrated for other flammable <strong>gas</strong>es to specification<br />
eg. LPG, Propane, Butane, etc.<br />
SENTRO eModule<br />
CARBON DIOXIDE/ METHANE GASES • INFRARED SENSOR<br />
SENTRO eModules with an infrared <strong>sensor</strong> are used for monitoring environmental<br />
concentrations of either carbon dioxide or methane <strong>gas</strong>es.<br />
This <strong>sensor</strong> is highly specific to the selected <strong>gas</strong> and exhibits consistent sensing<br />
accuracy with superior long term stability; so minimising calibration and<br />
maintenance.<br />
The essentially linear response and high sensitivity of the <strong>sensor</strong> means that it<br />
can be calibrated equally well for low <strong>gas</strong> concentrations and high<br />
concentrations up to 100% by volume.<br />
TX6353.242 Methane 0...100% v/v<br />
TX6353.243 Methane 0...100% LEL<br />
TX6353.253 Carbon dioxide 0...2000ppm<br />
GAS SENSING MODULE SETTINGS<br />
Gas sensing modules are normally supplied with preset function data and no<br />
further setting-up will be necessary – SENTRO will immediately recognise the<br />
module and its settings when it is loaded.<br />
Module parameters can also be setup to individual requirements when requested.<br />
Scaling, duty text and setpoint alarm values are pre-programmed.<br />

convenient and rapid calibration...<br />
A <strong>gas</strong> <strong>sensor</strong> will not protect lives and plant equipment if it is out of<br />
service, waiting for a complex calibration procedure by a specialist<br />
technician – so swift and simple re-calibration, at the point of use, is<br />
crucial to efficient performance and safety.<br />
SENTRO achieves this in a choice of<br />
three uniquely simple ways:<br />

• False alarms will be automatically inhibited during change-out.<br />
• The SENTRO cover stays anchored in place, ready for 'quick' replacement.<br />

• The same thing can be done<br />

SENTRO GAS SENSOR/TRANSMITTER<br />
efficient maintenance...<br />
Service and maintenance can be a high cost factor in supporting an<br />
efficient and safe <strong>gas</strong> monitoring programme.<br />
One of the main objectives of SENTRO was to move on from<br />
traditional methods and produce a <strong>sensor</strong> that could be easily<br />
maintained by Plant Engineers without the need for intervention by<br />
qualified specialists.<br />
Whatever service needs to be carried out, it is simple and quick –<br />
engendering confidence in the product so ensuring a greater level<br />
of plant safety.<br />

choice of power and output options...<br />
One of the most important characteristics of a <strong>sensor</strong> is its ability to<br />
integrate directly in a trouble-free way, with other plant equipment<br />
and monitoring devices. SENTRO has no equal in its choice of direct<br />
power-up options and a range of fully conditioned output signals to<br />
satisfy most plant preferences – just forget about additional<br />
power-packs or signal interface devices; they won't be needed.<br />
