The Matsushima Microwave Barrier Switches from HMA INSTRUMENTATION provide for excellent performance, even in demanding environments. These switches detect when materials have reached the upper and lower limits set in advance for each silo, hopper, or any other kind of container.

The reception sensitivity can be adjusted easily, as the level of microwaves received is indicated in real-time on the receiver display. Microwaves can be transmitted within a maximum range of 100 m. Four different frequencies are available so as to prevent interference between nearby switches. An explosion-proof barrier switch can be used in hazardous areas (Zone 1 and 2) for a range of applications.
