Representative sampling is of decisive importance for in- and on-line particle size analysis. Sympatec provides a family of representative samplers, which can be used in in- or on-line applications with current pipe diameters from 35 mm to 660 mm.
For representative sampling all areas of the cross-section of the process pipe has to be sampled equally weighted. TWISTER scans the pipe diameter on a spiral line with constant path velocity, starting in a shielded parking position at the wall, moving to the centre and continuing to the parking position at the wall, without intermediate stop in the centre.
TWISTER 50For pipe diameter of 35 mm to 80 mm in standard, GMP and ATEX applications. |
TWISTER 100For pipe diameters of 100 mm, expanded to 150mm, for standard and ATEX applications, suitable for use with in-line MYTOS. |
TWISTER 50 ATEX/GMP with drive unit |
TWISTER 100 with pipe reduction to 80 mm |
TWISTER 150/200For pipe diameters of 150 mm, expanded to 200mm, for standard and ATEX applications, suitable for use with in-line MYTOS. |
TWISTER 660For pipe diameters of 300 mm to 800 mm, for standard and ATEX applications, suitable for use with on-line MYTOS. |
