Equipment-level Sensors and Controls
Finalists in the Equipment-level Sensors and Controls category for the 2012 Product of the Year competition
Remote control portal
The tool from Synex Controls provides a private portal for remote Web-based access to a facility’s boiler room controls. In conjunction with the ModSync sequencing system, users can access real-time system status, make adjustments, monitor maintenance schedules, receive e-mail and text-message alerts, and review systems reports. The user-friendly, full-color, icon-based interface is available for multiple administrators using Web browsers, Web-enabled phones, and an iPhone app. The system can be retrofitted and customized, and its features include response to outdoor temperature, setback scheduling, system interface flexibility, multiple setpoint modes, trending and performance monitoring, alarm status and history, and building integration.
GE’s Limitamp AR arc-resistant medium-voltage motor control delivers increased safety, reliability, and ease of maintenance for industries like petrochemicals and gas, meeting the IEEE C37.20.7 standard and providing Type 2B protection. Arc flash energy is contained and exhaust gases redirected up through vent flaps at the top of the enclosure and away from the system through a plenum. Features include heavy-duty, reinforced 0.12 thick steel side panels and a fully isolated low-voltage compartment in the front door. This control is available for one- and two-high full-voltage nonreversing 400 A, NEMA 1, 50 kA motor starters, rated for 2.4 to 7.2 kV.
Arc flash relay
The Littelfuse PGR-8800 arc-flash relay protects personnel and equipment by rapidly detecting developing arc-flash incidents and tripping the circuit before significant damage occurs. This relay can detect an arc flash in less than 1 msec, and it detects both current and light to minimize nuisance trips and to provide overcurrent protection. The compact, stand-alone unit features up to 24 light sensors, including optional fiber-optic cable sensors that can protect difficult-to-reach compartments. The relay offers adjustable light level and wide-angle detection, built-in LED to indicate local sensor health or trip state, and application tool s to help determine sensor placement and maintenance schedules.
Variable frequency drive
Cooper Crouse-Hinds’ ACE Series explosion-proof variable frequency drive (VFD) can be safely and reliably installed in Class I, Division 1 or 2 hazardous areas. Currently available up to 60 hp, this drive features a NEMA 7 enclosure with active cooling technology that allows the VFD to be housed inside the classified enclosure without the risk of overheating and failing while operating in ambient temperatures up to 50 C. In addition to installation savings, this drive provides soft start capabilities and built-in, real-time diagnostics. It can lower energy consumption by allowing a motor’s power level to be adjusted exactly to performance needs with an explosion-proof keypad and window.
