Level Transmitters & Gauges


AT200 Magnetostrictive transmitters

The AT200 is a magnetostrictive transmitter (see AT100) that is mounted on the outside of a magnetic level gauge. The magnets inside the level gauge float activate the transmitter through the wall of the chamber. The transmitter is therefore completely non-contact and can be mounted at the top or bottom of the chamber.

The transmitter can be left inside any chamber lagging or heat tracing and for high temperature applications we can add a 90° bend in the rod to remote mount the electronics.
