Magnetic Suspension Balance – Ultra High Vacuum up to 150 bar


On points

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

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.



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 of this instrument offers a broad range of applications. It enables measurements in conditions spanning from ultra-high vacuum to pressures of up to 150 bar and operates within a temperature range from -196°C to 2400°C. Additionally, it accommodates the handling of corrosive and toxic media through the use of specialized coatings applied to the metal measurement cell. This versatility makes it suitable for a wide array of challenging environments and substances.

Glass version

When working with highly corrosive media, the glass version of the instrument is recommended. The glass version incorporates fused-in glass components for sensitive parts within the measurement cell, such as the levitation magnet and the iron core used for the position sensor. The magnetic coupling and automatic decoupling functions are analogous to those of the metal version.

The glass version offers a temperature range of up to 900°C and is suitable for operating within a pressure range of up to 1.3 bar. This configuration ensures reliable measurements while safeguarding sensitive components from the corrosive nature of the media being studied.
