On the output side, the TTA has an analogue (4-20mA/0-±10V) output which can be linearised to suit the application, as well as two SPDT change over contacts rated to 3A at 250V.

The TTA has a wide power supply range of 18-264 VAC/DC which means that it is compatible with most standard power sources.

Features of the connector include:

• Tested to 750 plugging cycles.
• Can be re-terminated up to five times without any loss of functionality.
• Full metal connector passed through shielding from cable.
• Snag-less constructions means plastic lugs don’t get broken off.
• Able to be used in Profinet networks.
• 50 microns of gold plating on the contacts, standard domestic/commercial connectors come with <10 microns.  This in conjunction with larger flatter pins means that the connector is much more durable and resistant to vibration.

Hadar Lighting have announced that their innovative LED HDL106 floodlights for Zone 1 Hazardous Areas have received third party certification through SIRA for both ATEX and IEC Ex applications.

Hadar Lighting’s Engineering Director, Barry Thompson, commented, “It is a wonderful start to the year for us as we’ve been showing the units to customers, several of whom had them on trial, for over 6 months now whilst we awaited for the necessary exhaustive certification tests to be completed.

“The benefits of LED technology are now well known and established in that they produce purer light, use far less energy, weigh less and last far longer than traditional sodium or halogen equivalents. For Zone 1 Hazardous Area applications, however, there were very few products on the market that could deliver these benefits within the very strict requirements of a Zone 1 certified fitting.”
“In addition, Zones 1 and 2 applications, by their very nature, tend to be in places difficult to service – derrick lights on oil rigs, or floodlights in petro-chemical plants, for example – which might also involve downtime whilst lighting is renewed. Traditional lighting options, which take a while to warm up, have a limited lifespan ranging from 22,000 hours for high pressure sodium down to as little as 3,000 hours for halogens with many companies exchanging bulbs en masse at half life stage during regular maintenance operations. The HDL106, which requires no warm up, has a lifespan of at least 10 years without any maintenance in line with industry’s preferred ‘fit and forget’ requirements.”

Power consumption of the new floodlights is approximately 40% of traditional equivalent, with adjustable beam dispersal patterns of between 5 degrees and 120 degrees meaning the light goes where it’s designed to go rather than being wasted.

Hadar Lighting Divisional Director, Bob Scott, continued, “Due to the LED technology, the lights are initially more expensive than traditional counterparts, but very quickly pay for themselves through low maintenance and power requirements. They really have very few adverse features – they are easy to fit, cheap to run, very rugged, give off a fantastic white light, are instantly on or off with no warm up period and last, but not least, they are environmentally friendly to dispose as they don’t contain mercury or other hazardous materials. We see the new technology as the way forward with the HDL106 becoming our flagship product – we’re currently dealing with enquiries from all over the world, particularly from the Oil, Gas & Petrochemical sectors.”

Client Requirements

The two ammonia vessels at Yara Sluiskil operate at high temperatures. The vessels are internally insulated to prevent the shell from overheating. Constant monitoring of the skin temperature (approximately 110 to 150°C) is required to detect the location of any cracks in the internal insulation, allowing any hotspots to be identified and managed from an early stage. Monitoring was previously achieved by using an electrical resistivity system. This system became outdated and was no longer supported by the original supplier. The temperature of the vessel can rise up to 350°C when a hotspot occurs. These hotspots create great stress on the vessel and repairs are needed to be completed during a turn-around.

Application

Two ammonia vessels were installed with monitoring cables in 2008 and 2009. The initial installation on Vessel 1 was conducted during a scheduled maintenance shutdown. The Sensornet team worked around the clock along with other service companies to ensure the installation was completed within schedule. The sensing cable on Vessel 2 was installed at the manufacturer’s facility in The Netherlands before the vessel was relocated to the Yara site. Final connection and commissioning was then conducted in a matter of days. Both projects utilized the Halo DTS complete with the integrated multiplexer for bidirectional testing. These were deployed in local control rooms and communicated with the site SCADA system via OPC tags.

The existing electrical resistivity monitoring solution became outdated and was not supported anymore by the original supplier. Temperature readings were presented as percentile figures based on maximum and minimum values which was not ideal. Temperature readings were also taken with infra red thermometers. Although these provided valuable data they could not be deployed on a permanent basis and would not provide a fully distributed temperature profile of the vessel

The Sensornet Solution

Substantial Benefits

The Sensornet vessel monitoring solution provides a complete temperature profile of the reactor vessel with near real-time refresh rates. Monitoring the entire vessel online enables the process to be managed to ensure that the vessel performs within its operational tolerances. This results in longer runs times between cleaning and maintenance periods. Moreover the operator can be safe in the knowledge that the vessel is operating safely.

Measurable Performance

The Sensornet range of DTS offers the most advanced performance available today. Measurement times of down to 10 seconds and temperature changes of better than 0.01°C can be detected by the sensing cable. For each of these vessels a total of 1km of sensing cable was deployed directly onto the skin. This gives a total of 1000 measurement points and provides the client with comprehensive thermal modelling of the reactor vessel.
