Enclosure range fits analytical bill
PS Analytical needed an enclosure manufacturer that could provide products for numerous applications while maintaining a corporate style for a range of products, particularly for process applications.
PS Analytical of Orpington, Kent was looking for an enclosure manufacturer that could provide products for numerous applications but at the same time the company wanted to have a corporate style for its range of products, particularly for process applications For over 20 years PS Analytical has been producing instruments for automating the laboratory

Recently the company has extended its applications scope to detecting mercury emissions from coal-fired utility stacks and monitoring mercury in the petrochemical industry.
When exhaust stack emissions are monitored a probe is located at the top of the stack and samples sent to analysers that can be located almost anywhere at ground level.
The samples are conditioned in PS Analytical's proprietary system and then the sample transferred to the measurement spectrometer.

Versatility, cost effectiveness, maximum security and scope for expansion are the perfect features offered by Rittal's new TS8 enclosure system.
Rittal launches new climate controlled cabinets
With the launch of Rittal's new TS8 enclosure system, a full range of adapted climate control products is immediately available.
Data are then transferred to the control room where the results are continually monitored and checked.
Using a combination of Rittal enclosures, chosen for their complementary design appearance, the analysers were built into three Rittal Vario Module enclosures that could be linked together and used on a desk or built into a Rittal floor-standing PC enclosure.
The connections for mains and signal connectors are housed in another enclosure that is built into the side of the PC enclosure.
The new Top Therm cooling unit is installed because many of the units will be used in countries where the ambient temperature is higher than the maximum operating temperature of the equipment and therefore refrigerated air must be used.
When the analysers are built into the PC enclosure they are easier to move around and make a portable unit.
The stack gas analysers are located at electric utilities coal-fired stacks and this places constraints on the overall size due to the fact that the units must be moved around the stack and the physical size of the lift housings is limited.
The lift space is typically 1550mm high, whereas the normal enclosure height is 1800mm.
PS Analytical put this problem to Rittal which was able to produce a unit which could carry 21U of equipment with an overall height of 1500m, and so would fit in the lift.
The problem was compounded by PS Analytical having to complete the installation in less than six weeks.
Despite the enclosure being a special build Rittal was able to deliver ready for the equipment to be installed and delivered in the time frame allowed.
Dr Peter Stockwell of PS Analytical said: "We have worked with Rittal on several projects and on each occasion they have been able to meet our service levels and the products have been delivered on time with the same corporate appearance.
Technology transfer is all about people and those people who have interfaced to PS Analytical have responded well, to our mutual benefits". Request a free brochure from Rittal ...
