Rittal and the IEC 61439 Standard D
High-reliability
outdoor cabinets and shelters
A ll-weather, application-specific field protection
solutions based on standard designs are available from Intertec - the composite GRP material expert. Intertec has developed special fabrication techniques for creating tough and durable cabinets and shelters for harsh outdoor operating environments. We employ composite sandwich constructions with inner and outer GRP skins enclosing cores of insulating PU foam (or mineral wool if long fire resistance times are required).
This construction technique combines strength and rigidity with a high degree of environmental protection. Three standard forms of cabinet and shelter provide platforms for a very broad range of outdoor equipment needs. Our heritage has allowed us to develop the complete service for designers and users of remote and outdoor-based equipment including: * all-weather enclosures, cabinets and shelters * a
huge range of accessory options (heaters, ventilation, mounting...) * design and manufacturing support to enable application-specific solutions

esign engineers should be aware that the the IEC 61439 switchgear and controlgear systems standard will take effect from November 2014. This standard also applies to wall mounted control panels as well as floor standing power distribution assemblies. For the smaller control panels with current ratings of below 630A, the ratings of the busbar system and controlgear components must be de-rated in line with the standard. A key feature of the standard is the calculation of the maximum internal temperature of enclosure. To assist the design engineer Rittal can supply Therm software that will calculate internal temperature and Power Engineering software that can design the panel layout in line with the standards. For further information regarding Rittal solutions and assistance with compliance to IEC 61439, please contact Mark Guest

New Combustion Dynamics Instrumentation Brochure P
brochure
CB Piezotronics has released a new Combustion Dynamics Instrumentation
highlighting application-specific
solutions for monitoring gas turbines. It features sensor placement illustrations and is designed to help gas turbine operators select the optimal pressure sensors and accessories for monitoring gas turbines. With the trend toward increased fuel efficiency and low NOx emissions, today's gas turbines operate more efficiently but have to be closely monitored and controlled to avoid combustion instability. This can damage components in the combustion chamber such as nozzles, baskets and transition pieces, as well as downstream components such as blades, resulting in avoidable downtime and revenue loss.

LOW-COST,LOW PROFILE TEMPERATURE TRANSMITTER
The Labfacility 300TXLP is a compact ,low-profile 4-20mA temperature transmitter with an overall height of only 23mm. It can be housed in low profile enclosures or in a DIN block ter- minal head. There is a choice of ranges for Pt100 and thermo- couple types J,K,N,T,R & S.
A key feature of the transmitter is the minimal-interaction span and zero calibration potentiometer action which is time saving and convenient when scaling or offsetting; an exceptionally

wide range of adjustment is provided by the potentiometers to allow for easy re-calibration of the 4-20mA temperature range.
The 4-20mA loop powered transmitter provides an accuracy of ±0.2% of span for thermocouples type J,K & N and ±0.1% for Pt100 sensors. The output is directly proportional to the mV input signal for thermocouples and to the temperature input for Pt100 sensors.
The 300TXLP is CE and RoHS compliant and is guaranteed for 2 years.
