SENYA FINLAND High Volume Air Sampler SNOW WHITE SENYA FINLAND High Volume Air Sampler SNOW WHITE 2 JL-900 SNOW WHITE is a high volume air sampler. It´s ment for hard, continuous outdoor use. The baseframe structure is so strong that whole unit can easily be installed even on four rocks if neccessary. For installation just connect the mains cord and start sampling. SNOW WHITE is very easy to use and in the designing work users opinions were listened carefully. Pump control can be made with frequency converter thus giving possibility for changing volume flow. Panel meters are microprocessor based and they do all neccessary calculations that you need; total volume and total time. Air volume is calculated from pressure difference over calibrated orifice, also in carbon line. Carbon line is equipped with valve, so it can be closed totally. Pressure drop when using Whatman GF/A glass fiber filter is c.10.000 Pascals. Pumps maximum efficiency is 20.000 Pascals so there is lots of reserve power to hold volume flow stable even when filter gets filled. Filter cassette, which is made of aluminium, can be loaded already in laboratory thus avoiding problems with rain and wind outside. Pipes and supporting frames are made of stainless steel which is electrochemically polished after fabrication. GRP, glass reinforced plastic covers are thick enough to withstand even small flying stones or hammering. GM-probes can be installed to measure radiation concentration on filter.They can be used for emergency preparedness purposes; early warning system.

SNOW WHITE does not neccessary need any platform for installation. However if she is installed on the ground it is a good thing to cast a concrete platform fro installation. This platform should be wide enough so that station operator can work on it when changing filters or doing service work. JL-900 SNOW WHITE is normally placed on a concrete platform, 10-15 cm thick. Normally customer leads electricity and data cables to sampler,under ground for safety reasons. For that purpose there should be placed pipes, tubes for them before laying the concrete. Cables should run c. 50 cm apart from each other. Electricity cable: for pump UNIT, 3- phases, 1,2,3+0+PE, depending on distance, 9kW. for measuring unit: 1-phase, 1+0+PE from stations UPS, 250W. Data cable: We will provide when we know the needed length. SENYA 9G/Lumikki/Man/preinstallation FINLAND SNOW WHITE 7 SENYA SNOW WHITE 1. Take OFF the lock springs 2. Pull OUT the shafts 3.

Pneumatic tubes are connected on both sides of Pressure difference orifice. Orifice is situated In the intake tube under filter. 2. Penumatic tubes are connected to Pressure Difference Transmitter ( PDT ). PDT transforms pressure difference to 4 - 20 mA message. 3. This 4 - 20 mA message is routed via panel meter and data logger ( QLC50 ). 4. Panel meter calculates and store this message into air flow ( m3/h ) and total volume ( m3 ). 5. Data logger calculates also this message into air flow and total volume. 6. Into data logger there has been connected also Static pressure sensor, which measures static pressure of air before the measuring orifice. 7. There is also connected a temperature sensor to measure air temperature, before the orifice. 8. With all this information a correction calculation is done to convert the air flow into air flow in Standard Temperature and Pressure ( STP ) which is demanded by CTBTO. 9 After all measurements and calculation the data string is produced into RS232 and RS 485 ports. 10. In RS485 port the data string is in a form of CTBTO specifications. 11. If properly connected to PC, you can ask for this data string by writing <POLL> ENTER 12. Same out put is done automatically every time, when sampler is START or STOPPED. Also when either of two tamper swithces is activated the same data string is sent automatically. 13.
