STA MSB PT 1

Magnetic Suspension Balance – Ultra High Vacuum up to 150 bar

Description

On point

With the magnetic suspension balance LINSEIS MSB PT 1, gravimetric measurements in a wide temperature and pressure range and under aggressive media can be done. Such a magnetic suspension balance consist of a balance for recording the measurement values, a suspension coupling which carries the weight of the sample, a sensor for the position measurement of the levitation part and a control unit to control the suspension coupling.

The contact-less transmission of the sample weight is realized with a levitation magnet and a holding magnet. The levitation magnet consists of a permanent magnet and the holding magnet consists of an electromagnet hanging on the balance. The position sensor delivers the actual position of the levitation magnet and the PID controller makes a stable levitation position with the electromagnetic force as the actuating variable.

Through the magnetic coupling a micro balance can be set up at environmental condition. Therefore the balance is protected from high temperatures, pressure and aggressive media.

STA MSB Measuring system

Density

With the Archimedes´ principle the density can also be analyzed with the magnetic suspension balance. A mass with known volume will be weighed. With the buoyancy of the sample the density will be calculated. With a compact construction of the magnetic suspension balance the density can be analysed in a large temperature and pressure range.

STA MSB Temperature Control

With the magnetic suspension balance dimensions like

  • sorption,
  • diffusion,
  • surface tension,
  • and density can be measured easily.

Furthermore chemical reactions e.g.

  • corrosion,
  • decomposition,
  • and combustion will be recorded
  • and production processes can be simulated (coating, polymerisation, dehydration, etc.).

Glass version

For the measurements with highly corrosive media, the glass version will be used. Sensitive parts in the measurement cell – for example the levitation magnet and the iron core for the position sensor – are fused-in glass. The functions of the magnetic coupling and of the automatic decoupling correlate with the metal version. The possible temperature is up to 900°C and the pressure range is up to 1.3 bar.

Software

All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a STA measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.
