BLM magnetostrictive level transmitter WIKA

Description

BLM is a magnetostrictive level converter for Bypass level converters used in for continuous measurement of liquid levels , based on the determination of the position of the magnetic float according to the magnetostrictive principle.

It is mounted on the outside of the Level Converter Bypass.

The measurement is triggered by a current pulse. This flow ucreates a circular magnetic field along a wire made of magnetostrictive material, which is live in the sensor tube. At the measurement point ( fluidlevel ) is a cylindrical float with permanent magnets, which they are such as converter position and of which Polish lines are under I say cat at impulse Magnetic field.

The magnetic field of the float strains the wire. The superposition of these two magnetic fields triggers a mechanical ripple in the wire. This is finally wires in the housing Sensor s piezoceramic receiver convert v electrical signal.

Measured delay Spread facilitated by very precise determination Initial points mechanical Torsion waves and s here position float.
