CARLO GAVAZZI

A range of environmental sensors to measure variables such as CO2, humidity and airflow has been launched by Carlo Gavazzi. The CO2 sensors use non-dispersive infrared technology to measure in the ranges 0-2000 or 0-5000ppm. The sensors automatically recalibrate to compensate for drift caused by ageing. The humidity sensors use a thin-film polymer. The material’s dielectric properties vary according to ambient humidity. The sensors are claimed to be accurate within +/-3% in the range of 10% to 90% RH. The air velocity sensors, based on thin-film anemometry, is claimed to be accurate up to flow rates of 20m/s. The temperature sensors are said to be accurate to within +/-0.3C at 20C.

TITAN

Two BACnet-enabled controls have been launched by Titan Products. The CCI-2X485 is a Modbus to BACnet gateway designed to enable third-party products using the data transfer protocol to interface with the BACnet control networking protocol. The firm has also launched the CCI-2242, which is a BACnet controller that can be used to monitor and control building services plant. The unit is available with a built-in display that incorporates an RS485 port to drive or monitor slave devices. Both units are available with 24V AC/DC, 115V AC or 230V AC supplies.

KINGFISHER

The Intelux lighting control system from Kingfisher Lighting allows users to switch or dim highintensity discharge lighting systems and wire-wound control gear. The system works by reducing the power fed to the lighting circuits. Depending on the lamp type, lighting levels can be reduced by up to 30%. As the system is installed between the incoming electrical supply and the lighting circuit, existing systems can be adapted with minimum intrusion. The lighting circuit can be programmed to switch on or off, or to dim to a predetermined level in a particular time schedule.

PHILIPS DYNALITE

The operator interface of the Philips Dynalite MapView lighting control system management has been simplified. The graphical user interface provides a pictorial representation of the space and enables operators to configure and monitor all devices on the network with the click of a mouse. The system enables operators to program complex lighting tasks into the automated macros, make manual changes easily, implement timed events, access performance data and do lighting tests. When used with the DLight III server, the PC-based system provides a scalable, simple-to-use software application to enable facility-wide lighting control, programming and energy management.

SONTAY

Two new wall-mounted sensors from Sontay have an extended range and field of view to drive energy efficiency in commercial and public buildings. The LL-W-V is a light level transmitter which uses a photo diode to detect light in the 10–2000 lux range. It provides a linear 0-10V DC output. The OC-W-LV is a passive infra-red detector for monitoring room occupancy. It has a time delay adjustable between 10 seconds and 30 minutes. The curved design makes it less obtrusive.
