Products Editor’s Choice Preventing road tunnel fires Flexible, lightweight and precise
Based on the SICK LMS511 laser sensor with the TIC 102 profiling system and integrated with thermal imaging cam- eras, the new SICK Hot Spot Detector detects potentially dangerous situations in free-flow traffic so a suspect vehicle can be diverted before entering a tunnel. Developed by SICK’s Swiss subsidiary ECTN AG, the new Hot Spot Detector is able to detect potentially dangerous over- heating on chassis or cargo in virtually any type of vehicle - from buses and low load- ers to high sided trucks and tankers. Every vehicle greater than 7.5 tonnes is guided into the lane where the Hot Spot detector is sited before entering the tunnel.
Here, while the vehicle is moving freely, the laser sensor measures it in 3D and the thermal imaging cameras create a thermal profile of it. The combined 3D thermal image is assessed against one of 28 categories, which each have the approved thermal thresholds for specific parts in locations appropriate to that class, including exhaust system, load,
brakes, wheel bearings,
engine etc. Any significant deviation from a normal temperature will alert the tunnel police who can pull the vehicle over and implement a thorough inspection. The SICK Hot Spot Detector is an all weather IP66 protected system offering assurance against fire hazards in all weath- ers from -25°C to 55°C. As many road tun- nels are found in mountainous regions, or close to rivers and estuaries, resistance to environmental conditions is also important. SICK

Mounting frames available in plastic HARTING has introduced plastic versions of its
connector mounting frames for the Han-Port(R) front panel interface system. The new option pro- vides a lightweight solution for users who need to connect external devices to controls and sys- tems in control cabinets or machine enclosures for diagnostics or maintenance purposes. The mounting frames are available as single and double versions and users can choose between transparent and metallic finishes for the covers. A 3mm double-bit closure is available for locking the cover. The use of plastics and an IP65 degree of protection (with closed
cover) allows the new plastic mounting frames to be deployed in harsh industrial environments.
The mounting frames feature a spring mechanism that lifts the unlocked cover upward by 30°, allowing users to easily detect whether the cover is closed. The plug sockets and/or data modules are inserted and snapped into place in the new Han-Port(R) mounting frames. HARTING

Relay system suited to US market out any limitations.
Phoenix Contact’s Rifline industrial relay system has now received CSA certification and has been approved as a UL com- patible component.
This means it conforms to the standards and guidelines of the US and Canadian mar- kets and can be deployed in these immediately and with-

The modules of the relay system range from a slim 6.2mm coupling relay to small contac- tor replacement. The most pow- erful relay can switch voltages up to 400V. Universally plug- gable components ensure high machine and system availability due to fast replacement during maintenance. The relays are offered as a complete module for all common input voltages. The modular system also enables the implementation of custom solutions. Phoenix Contact

Well suited for accurately controlling the temperature to ±1K in small enclosures, providing 100W of both heat- ing and cooling, Rittal’s ther- moelectric cooling unit is compact, light weight and has low vibration operation. It is also well suited for com- mand panels and support arm systems.
The unit may be fitted either externally or, if space around the enclo- sure is at a premium, internally, leaving only 55mm protruding outside. Rittal’s cooler may be installed either horizontally or vertically on the wall or door of the cabinet, and the optional master/slave adap- tor can be used to connect multiple units, providing a scalable, mod- ular solution.
Peltier technology requires no refrigerant or chilled water to func- tion - an electrical power supply is all that is needed. The range con- sists of only two units - a DC and an AC variant - which accept 24V DC and 100-230V AC power supplies respectively. The only moving parts of Rittal’s thermoelectric cooler are fans moving air across either side of the solid state element which reduce the risk of component failure and maintenance requirements as well as less vibration and noise - both acoustic and electrical.

Enter 218 UPS for next gen data centres
Power management company Eaton has launched a new range of uninterruptible power supplies (UPSs) designed to meet the needs of next generation data centres by bridging the gap between energy effi- ciency and scalability. Energy efficiency is rising up the prior- ity list for data centre operators as energy prices continue to rise and energy sup- plies become more unreliable. The new Eaton 93PM units, in power ratings from 30-200kW,
are designed with these
needs in mind. Using Eaton technologies including Energy Saver System (ESS) and HotSync, Eaton UPSs adjust to power conditions and demand to maintain the best level of efficiency in any situation. The flexibility of the new 93PM UPSs is
a result of the units’ modular design. This makes it simple to scale the system as load demands change without increasing the footprint, enabling users to reduce capital expenditure and adopt a ‘pay as you grow’ approach. The inclusion of Eaton’s patented Hot Sync wireless paral- leling technology also means a system can be designed, or is scalable, up to a power rating of 800kW, maximising avail- ability without compromising resilience and reliability. Total Cost of Ownership is low as the UPSs enable users to take full advantage of the operational efficiency provided by Energy Saver System (ESS) mode. ESS automatically and continuously matches the operation of the UPS to the incoming power quality allowing an efficiency of 99% to be achieved. When required, ESS

transitions the UPS seamlessly to double conversion mode in less than two mil- liseconds and delivers an unmatched efficiency of up to 97% whilst at the same time removing any abnormalities in the utility power. The new 93PM UPSs also have a power factor of 1.0 and so enable users
to further improve their Power Usage Effectiveness (PUE).
The new UPSs incorporate a web inter- face that allows them to be managed and monitored remotely, and to be easily inte- grated with facilities management sys- tems. Eaton’s Intelligent Power Manger (IPM) software is also supplied as stan- dard with the new UPSs. Eaton
