TGA MSB PT 1
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.
