Confidently Detect Leaks and Monitor LNG Assets with Sensornet’s SIL2 Leak Detection System
In conformance with IEC 61508 guidelines for functional safety, Sensornet’s SIL2 rated and ATEX certified leak detection system offers an intrinsic de-risking of cryogenic assets like LNG and LPG facilities with a ready-for-use instrumentation is achieved. This Sensornet solution takes the burden of proof off the mind of the operator, while offering cost savings on installations and industry acclaimed reliability.
A distributed fibre-optic leak detection system capable of measuring temperatures from -196 deg C to 300 deg C, it has at its core the ATEX certified Sentinel™ Distributed Temperature Sensor (DTS), with a range of 45km, and temperature resolution as fine as 0.004deg C suitable for both linear assets like pipelines, storage tanks and vessels. In conjunction with the DTS is the patented Automatic Trip Testing System (ATTS), to achieve a Risk Reduction Factor (RRF) of 1,000 to 100 and Probability of Failure on Demand (PFD) of 10-3 to 10-2 in a single instrument package.
The onboard logic solver validates SIL2 service levels by creating random temperature events on the sensing fibre. Alarms reset only when confirmed as a test event, thus ensuring that the system is actively monitoring for leaks.

Twenty years of Being First in DTS
Sensornet celebrates 20 years of being first in the Distributed temperature sensing industry in July providing valuable monitoring tools into Multiple industries.
Sensornet – Pioneers in DTS technology
We began life on 14 July 1997 as a Spin off from Kings College London. Initially set up as a consulting business to develop Distributed Temperature sensing for the Oil Well Monitoring area we quickly moved on to manufacture and full production being backed by Shell Technology Ventures.
Now part of the Nova Metrix group, Sensornet continues working closely with our customers consistently at the forefront of DTS instrumentation.
These partnerships have allowed Sensornet to be the world’s first in the following areas
- First to reach a range of 30Km in Multimode fibres in 2004
- First to provide a class leading temperature resolution of 0.04C in an oil well in 2006
- First to provide a portable DTS (Oryx+) for extreme conditions from -40C to +65C in 2007
- First DTS installation for LNG in 2008
- First DTS installed on an Offshore windfarm in 2010
- First Combined DTS and DAS system on a gas pipeline in 2012
- First DTS with ATTS unit for continuous self-testing and long term validation in 2013
- First SIL-2 rated DTS system in 2016
With over 600 proven installations in Oil& Gas, LNG, Power, Environmental and Geotechnical areas
Sensornet continue to put our customers’ needs first most recently upgrading to ISO 2009:2015 revision. This together with our strong platform of continual product development and innovation ensures we are very well placed to stay at the forefront of technology in order to meet our customer’s ever evolving needs in the diverse global industries we serve.
Sensornet First again putting the customer first!
Our priority at Sensornet is putting the customer at the heart of everything we do to ensure we continue to be at the forefront of our industry. With this in mind our most recent major project was updating our quality management system based on ISO 9001:2008 to meet the Quality demands of the next ten years and beyond by implementing the latest issue ISO 9001:2015.
The challenges faced by business today are continually changing and ISO 9001 has been updated to take this new environment into account. For example, increased globalization has changed the way we do business and we operate more complex supply chains than in the past. In addition, there are increased expectations from all our customers and other interested parties based on more access to information. The latest ISO 9001:2015 meets these changing Global business and social needs.
Sensornet achieved implementation of the ISO 9001:2015 revision successfully by working closely with our ISO consulting partners QTP .
Key benefits of the latest ISO 9001:2015 revision Include: –
An increased importance given to risk based thinking, moving away from classical corrective/preventative action, this helps address organizational risks and opportunities in a structured manner. While this has always been part of the standard, the new version gives it increased prominence.
More effective communication, driven through a communications strategy this already included regularly speaking to our customers and suppliers to gain suggested improvements and feedback on our services and future products.
Continuously reviewing our Systems, Policies and Procedures to make them work for you.
Training our staff to ensure we solve any potential problems and find opportunities for improving before issues occur and putting greater emphasis on leadership engagement.
Finally, the ISO 9001:2015 revision helps integrate all the above to make sure Sensornet works as a team across departments to meet your changing needs quickly and effectively.

Sensornet launches longest range for DTS
In response to customer demands Sensornet has extended the range of the leading Sentinel DTS system. A single channel with multi-mode fibre now extends to 45km. Using a multiplexer this allows monitoring of 90km along a single pipeline. When used with a 16 Channel Multiplexer it is possible to monitor a total of 720km.
The extended range DTS-XXR 45km offers the same temperature resolution of 0.1C in the field and the fastest measurement speed available. The whole range of Sentinel products are CE marked and meet ATEX standards.
Sensornet System achieves SIL 2
The Sensornet fibre sensing solution, Site Integrity Level DTS, has been awarded SIL2 certification. Used in critical safety environments such as LNG and Ammonia the system incorporates SentinelTM and the patented ATTS, Automatic Trip Testing System. The ATTS creates temperature events on the sensing cable which must be detected and acknowledged by the integral PLC controller. The tests are pseudo random and provide confidence that the leak detection system is actively monitoring these hazardous environments. The Sentinel offers the longest range and quickest measurement times which ensures that leaks are quickly reported to the site DCS.
The solution is provided in a cabinet set up compatible with all control room environments. The SIL2 rating allows users to meet Health and Safety requirements for their complete system, a first for fibre leak detection.
