TGA MSB PT 1 - Magnetic Suspension Balance

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
• a control unit to control the suspension coupling

Specifications

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.

Metal version

The metal version can be used for a wide application area. Measurements from ultra high vacuum up to 150 bar and a temperature range from -196 to 2400 °C are possible. Furthermore corrosive and toxic media are insertable. This will be possible with special coatings of the metal measurement cell.

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.
