Gas measurement without sampling systems
Extronics’ iLEL100 Zone 1 Gas Detector for the measurement of inline gas applications without sampling systems
Congleton, UK, 21st
April 2009: Extronics, a leading supplier and
manufacturer of intrinsically safe and explosion-proof electrical
and electronic equipment, has launched the iLEL100 Probe to monitor
the flammability (Lower Explosive Limit, %LEL) of a gas or solvent
vapour by direct insertion into a process or extraction exhaust
duct or alternatively to monitor for a range of Toxic
Gases.
Extronics iLEL100 direct process insertion probe has been designed on the basis of reducing high installation and commissioning costs as well as substantial maintenance costs.
"One of the main extractive system operator concerns is system blockage, if the sample has the potential to condense within the extraction system; the question that arises is how long will it operate for before it finally fails? The result of a blockage means expensive down time until the problem is resolved" said Paul Lazor, Sales and Marketing Director for Extronics.
To address this problem Extronics designed the iLEL100 probe for simplicity with no pumps, no aspirators, no filters, no narrow bore tubing and long sample lines, no heated line, no coolers or condensate vessels.
Narrow
bore pipe work was replaced with pipe diameters between 10mm and
40mm, the entire probe assembly is manufactured from
stainless steel and is positioned in situ hence the sample path is
extremely short and the probe is maintained at the process
temperature eliminating the need for heated lines or condensate
devices, as well as reducing response time to an absolute minimum,
which for safety applications is critical.
Extractive systems often require remote panels or enclosures to house the conditioning systems and analysers or sensors and if the area outside of the process is deemed to be "Hazardous" in accordance with the ATEX Directive then the panels or enclosures may have to be located a long distance away in a safe area. Extronics iLEL100 was designed in accordance with the ATEX Directive and is certified for use in a Zone 1 environment.
Maintenance
is labour intensive costly and time consuming requiring careful
scrutiny of any couplings, glands and seals, removal and
examination of pumps or the cleaning of aspirators as well as
changing of filters, all of which present a major maintenance
programme for the operator. The simplicity
of the iLEL100 probe is such that installation requires only the
fitting of a flange at the process analysis point and wiring back
to a panel, a calibration nipple on the iLEL100 probe assembly
allows gas to be passed across the head of the sensor on a
bi-annual basis to check the probe, (depending upon the
application) which concludes the extent of the maintenance
programme.
