HBM's differential pressure measurement solution
Precision rotating platforms For UHV analysis requiring extra mobility, eucentric motion about the mounting flange axis is n o w possible with Vacuum G e n e r a t o r s ; n e w RP100 series rotating platforms. Designed specifically for UHV equipment, such as cryostats and sample manipulators, these rotating platforms allow 360 ° continuous c o n c e n t r i c polar rotation and have a clear bore of 102 ram. The RP100 series provide primary rotation for a range of c o m p o n e n t s in mix and m a t c h applications. Used in pairs, the RP makes an ideal seal for rotation of UHV chambers, for example around incoming s y n c h r o t r o n beams. Other applications include
sample imaging (XPS, AES or SIMS), structural and i o n / n e u t r a l / a t o m scattering experiments.

New magnetic bearing turbodrag pump With low installation costs and virtually maintenance free operation, HBM claims that their n e w PDE300 differential pressure instrument offers an economical solution for sealing tests a n d level m e a s u r e m e n t , particularly on e n c l o s e d pressurised containers. The instrument can also be used in c o n j u n c t i o n with an orifice plate for flow measurement. The PDE300 comes with a c h o i c e of ten ranges covering full scale values b e t w e e n 100 mbar and 2 bar. It can be supplied for battery operation or for use w i t h t w o - w i r e a n d three-wire techniques (4 mA to 20 mA).

achieve an ultimate vacuum of < 10 m mbar and handle high gas throughputs at high inlet pressures with a backing pressure of up to 12 mbar. An optional temperature management systems prevents the condensation of c o r r o s i v e gases in t h e pump. Where process byproducts are deposited on the rotor the active magnetic bearing system is automatically balanced by the Digital Magnetic Bearing Controller. The p u m p c a n be installed in an orientation allowing versatile integration into a process system.
